high pitch noise - Galaxy Tab 10.1 General

Does anybody else notice a high pitch noise during the browser changing pages, like the noise you get from an old crt tv...or is it just my spidey hearing...

Have notice that sound to.
It comes from time to time, not always in the browser. Can be on homescreen/appdrawer
Sent from my GT-P7510 using XDA Premium App

I hear it as well

its really high frequency not many can hear it.....

I've heard it as well. It might be related to the display and the color transitions on each pixel. Either way I dont see it getting fixed so I would practice the art of "tuning it out"....also wildly successful with loud children and parents..

This is WIDE-spread audio defect in the Samsung Galaxy Tab 10 units. Might be a hardware defect unfortunately. I personally believe ALL units are defective since I have yet too see one without this defect.
Search "Samsung Galaxy Tab 10 Tablet widespread audio defect" on youtube and you will see a video of this defect.
I already exchanged it once and the replacement is the same.
This is an audio playback issue. For example, when you touch an icon or launch an app the tablet plays the Audible Selection sound ("tap/click" sound). After the sound plays the unit emits a high frequency whine from the speakers for a few seconds until the hardware amplifier is powered off by the system. Lowering the volume all the way on the tablet does not stop the noise. The strange thing is when using headphones the high pitch noise stops.
Its EXTREMELY annoying when you're in a quiet room since it happens every time you make a selection on the tablet.
I spend an hour trying to figure out if there was a way around it and almost decided to return my unit and ditch this model completely until I found that disabling Audible Selection in the Sound settings disables the "tap/click" selection sound when you touch the screen. This removes most of the situations where you get this noise from the speakers although it still DOES occur often when playing music or videos. Remember though with Audible Selection disabled you get no tap/click sounds when you use the keyboard or when selecting apps or buttons.
Edit: Im now convinced that this noise occurs when the audio amp is powered on but has no audio to play. For example the Audible Selection "tap/click" sound plays, once played the audio amp is still powered on for a few seconds and with no audio to process it emits this high pitched noise for some reason. You can notice this occasionally when playing other audio and videos w/ audio. For example, I launch a video which has delayed audio, the high pitched noise occurs until the audio starts to play.
Someone needs to fix this as its unacceptable IMO.

that's a teribble sound and lasts 2-3 seconds every click?

Yup, every single click lol. Its ridiculous and it drove me crazy.
I cant imagine how samsung engineers designed it like this and thought to themselves "Yes, this is good...." Its ridiculous and blows my mind how they can find something like this acceptable.

Sound Quality

Anyone having issues with sound quality on their focus. Everytime a sound is played a pronounced hiss and distortion comes through my headphones. When listening to podcasts this hiss is very apparent. I wanted this phone to replace my ipod touch, which does not have this issue. Feedback please, thanks.
I do not have feedback or hiss in any music or app so far. My headset works well too. Not sure but something is up. Have you tried a hard reset and a new set of headphones?
I do notice low overall volume out of the stereo port though...compared to the Tilt 2 my car stereo needs to be turned up about 25% louder to be equivalent.
i think the sound is amazing, especially the external speakers.
As for headphones, have you put the headphones all the way in? It could be that or either worn-out wiring on the headphone cable.
My complaint about the sound is the alarm. When u test a sound for alarm is its very loud. When u set an alarm to go off it seems 1/2 as loud.
Ok, I have done a hard reset and tried with several headphones. The pronounced hiss is still there with some crackling when I change a song. My best guess is the audio output is not working properly. I did test the headphones on my ipod touch with no distortion coming through. Will be taking a trip to the att store for an exchange. While there I will test the floor model to confirm a problem with my device. I hope they are in stock because I took the last one two days ago. I love the phone and with clean audio output I will love it even more.

what became of the at&t store test?
I've had my Focus now for 10 days and I am completely satisfied with it. I have never had any sounds like you describe. Just clean, clear and much better reception than I had on my 2+ year old Fuze that I dearly loved. It was hard to switch to Samsung for me, but I think I made the right choice. So far I really like my Focus and the display is nothing short of fantastic!
I'm having a similiar hissing issue with my Focus as there seems to be a noticeable hiss at low volumes. The sound quality does not appear to be as good as my iPhone 3GS or Zune 80GB.
I'm still within my return window so I'm debating returning the phone and exchanging it for a new Focus.
is there any update on this? i'm really cutting it close to my 30 day warranty period, and i'm not sure if i should return the phone or not.
my issue is that when playing music in zune, you can hear a very faint hiss. if you pause the music, you can hear it for a half second before it stops outputting audio.

Try switching it for a new one while you're still in your window.
Make the switch... before the deadline. No harm no foul and really it is a legitimate complaint.

Headphones - Hissing Noise

Guys,
Another day, another observation. When you plug in the headphones, do you guys hear a hissing/static/white noise for a couple of seconds initially. I am able to reproduce this every time I plug in my headphones (tried three different sets). I am not too bothered by it because the noise dies after 2-3 seconds. I also witness the same behavior when I pause a song.
I guess I am raising the topic here because am not sure if this is common across all WP7 devices (thereby making this a WP7 issue), if it is only my phone, or if it is common across all Venue Pros.
Thanks for any input.

I get the same noise, but mine is constant. Whenever a sound plays, the white noise/hissing in the background comes up and continues for 5-10 seconds after the sound is played and then goes out. Then when another sound happens, it does it again.
It almost makes using headphones unbearable.
I've tried multiple sets of headphones too, it does it on them all.
I think it may have something to do with the curved top of the phone and the fact that the plug doesn't go all the way into the device.
Anybody else have a similar experience?

I don't think it's that - if the curved surface was the culprit, the sound wouldn't vanish after a few seconds. It almost seems like a software issue.
Thanks for confirming the behavior!
I only hear the hissing sound for a few seconds after plugging it in to the jack...
Hearing a hissing on most smartphones is pretty common, in my experience. The better quality earphones you use the more you will notice it. The Nexus One did, the Venue Pro does, my N95 did a bit.
People I've called with the built in headphones/mic say the noise levels are so extreme they are unusable. Hopefully the free Bluetooth headset we're all getting will fix that issue...
Hello!
This is normal when companies use cheap DACs and amps for sound replication. The DAC turns on when you play sounds, and turns off when there's a period of no sound. If it's a cheap system, there's a noticeable base sound/noise that is added to your signal.
When you have music playing, that, of course, is drowned out by the music. Thus, you won't hear it unless you have really soft music, say, a few bars rest in your classical album or something.
The problem also is more noticeable with low impedance earphones (IEMs, for example).
A possible, easy way to fix this is to use an inline resistor/impedance cable on your headphones, since typically this noise does not vary with volume (in my experience). Then, you bump up the volume on your device... if it's powerful enough to do it. Otherwise, you'll have to inline resistor, a clean-sounding portable amplifier (powered by additional), and then your headphones. It gets pretty bulky...
Alternatively! Separate your music player and your phone. Unfortunately, the DVP has such a nice Zune interface. And still, with cheap music players you can hear the hiss if you're careful. I can hear this on iPods with my earphones still...
Sorry to hear about this! I was hoping that the sound quality would be decent. I might try to get an HD7 instead now...
Cheers!

Just to let you know, the HD7 does not have the hissing/static that the DVP does. I've tried the HD7, Samsung Focus and DVP and HD7 had the best sound quality in my opinion. The Focus sounds muffled compared to both HD7 and DVP.
I've got the same hissing noise on mine, but I think it's an issue with a crappy DAC as it's only there when there is sound. I was hoping to replace my Zune HD but there's no way that's gonna happen with this noise - it's AWFUL!
I'm really thinking about moving to a Samsung Focus. I loved this phone when I first got it, but over time I just uncover more and more I don't like.

Very true. Almost every phone I've used has this. It's more noticeable on some phones than others but it's nothing unique to the DVP.
Bringing this back to the top, I've observed something on my new model, though I could have sworn the one I sent back for a refund did not have this problem...and it only occurs with earbuds, and not ear phones (I have a big pair of medium to high quality full-size Creative earphones, the buzzing is not audible at all with them.
Since this phone seems reasonably crash-free, I'm reluctant to press Dell for a replacement, especially if, viola, all the DVPs have this problem. Mine seems particularly loud, but that may be a combination of the Zune Premium earbuds I'm using and other factors. As others said, it vanishes briefly if you pause a song (like the sound output is switching off to save electricity or whatever) but resumes immediately. I might be better off just going through various earphones and finding a brand that's of at least the quality of my current earbuds but minimizes the effect.
EDIT: Additionally, lowering the volume simply makes it much more noticeable.

[Q] Audio Jack Issues?

Just came across a disturbing report in a very recent Droid Life review of the Note 3 (from a list of N3 reviews posted on this forum) concerning "Audio Jack Issues". Anybody who treasures their hearing and uses their phablet for audio material (including movies, music, audiobooks, etc), especially using earbuds or headphones, might want to "listen up." The following is an excerpt from the review:
"...When listening to music through the 3.5mm jack, you are sometimes met with a very weak sound. It’s as if the sound of the music isn’t “full” or quite loud enough. Then, after a few minutes without touching anything while at full volume, the volume just explodes and you are left deafened by the surprise volume attack. Some people are pointing towards low-impedance headphones being the issue, but I have had the problem on multiple pairs of headphones, in-ear buds, through car decks, and everything else. It’s a very frustrating and reoccurring issue that I wish Samsung would find a cure for. Until then, I fear listening to music out of this device because I don’t want to go deaf. It might sound crazy, but it’s a very real issue that I experienced over the course of time I had the device."
I've had 3 Samsungs: a flip-phone a few years ago, a Fascinate 2 years ago, and currently Galaxy S3, and just preordered a Note 3. Of the three previous phones, two had infrequent but definitely-occurring audio issues where the volume changed unexpectedly. The flip phone blew out my ears once, and swore after that would never buy another Sammy (what a kidding-myself that turned out to be). What's unnerving is this seems to have appeared intermittently in multiple samsung phone models (the article reports yet another audio jack issue in the S4).
Chatted online with a VZW customer service rep. about this, who was really no help (wasn't her fault, i guess). She just regurgitated the company standard lines--14 days to return, restocking fee, can get a replacement if the problem occurs, etc. But she pretty much stated if there turns out to be a Note 3-specific issue, the customer is stuck with that model of phone; don't expect help from the carrier other than replacing with an identical unit might likely have the same problem; if you enjoy any kind of audio produced by the phone's audio jack, use it at your own risk. (Even more dicey is that it's intermittent--no guarantee you'll be able to demonstrate it to the carrier's service rep.)
Furthermore, i was one of those who got a free continuation of unlimited plan (thanks to the VZW ordering "system glitch" last weekend), which has been reported in the last day that VZW is going to honor contracts which show unlimited data. This rep completely contradicted that and claimed my data will be capped at 2gb at activation time. So with this diametrically-opposed chatter from VZW, what is one supposed to believe? Really suggests getting a satisfactory resolution from any carrier on a brand-specific phone problem like this to be wishful thinking.
Any thoughts or has anybody experienced thru-the-audio-jack sound issues with sammy phone products? My take is i'm not going to be on the bleeding edge of this one, too much of a hearing risk, cancelling preorder and wait for more reports on the N3 as time goes by.
For sure something is wrong with mine. (tmobile N3) The output levels are maybe half or less what my N2 can put out. I have carefully setup audio systems in my house and car, and it is unusable. Its also not USB compatible with the new Kenwood KMM 100u deck that plays FLAC files. It must be a glitch they can fix, i hope! The jack SQ sucks right now.
I hope mine won't have this problem.

I got that the first time you said it.
im experiencing this too with an AU Telstra Note 3.
ive tested it a bit and it seems like its 2 separate things to me, but I could be wrong.
firstly it seems like all EQs either crash or just lose their settings at random moments. this can be things like between track changes or when the 3G signal drops out. if you go back into the EQ panel it will kick in again, almost like it was off and you've launched it again.. very annoying. ive verified this with both the stock EQ and noozxoide. the difference in volume is minimal though, its more quality / bass / whatever EQ you use.
the second part with the volume dropping out completely only happens to me between track changes. if i pause the music for a couple of seconds then play it again, it will play at normal volume. fast forwarding between tracks is the most obvious since every other track will be minimal volume, and the ones in-between normal volume.
ive only tested this with google music. although my phone isnt stock now, the same behaviour was there out of the box. using etymotic earbuds with reasonably high impedance but i doubt thats the issue since pause/replay fixes it.
Doesn't happen to me on N7player or PlayerPro. (nor on videos in Dice, MX or VLC.)
Try not using stock apps if you have the issue. Might just be a stock problem.
I can't test Google music, I disabled that. Stock player itself is too annoying for me to try.

Got the same here. N9005 with Google Play Music. Sometimes it's also (it seems) input-triggered. Sometimes when I push Menu or Back button, volume goes down and when I open Browser volume goes up. I know this sounds like voodoo and I'm completely crazy but I got this situation some times now.
With original sound files this problem came very often but after installing sound mod, it became seldom but not solved.
Annoying!

I actually moved to the stock sammy app since it was irritating me so much. i have to say though, that if you can be bothered syncing a playlist to your phone that the sound is much better through that... hard to pick fault with.
i set up galaxy adaptive sound first, which is the one that plays high med low tones through left and right channels on your headphones independently and lets you tune it. found a much more balanced tone coming out after that, to which I then applied higher bass EQ settings from within the sammy music player and it sounds pretty good. some distortion on really heavy bass tracks at high volume, but very nice otherwise. MUCH BETTER than variable bass and audio volume on the google music player.
i think samsung neglected to test the standard music APIs and borked them, but their own proprietary ones work fine. the adaptive music filter doesnt work in any player apart from the sammy one I read.
since i cant cross-flash regional roms without voiding knox warranty i havent tried the updated EU roms, but maybe they fix it there?
Experiencing same problem on my AT&T note 3. Google Music tracks will randomly apply a shoddy EQ setting that is either too loud or too soft. Then the next track will be normal. It explodes my ear drums constantly. I have the EQ set off also, but that doesn't seem to matter. Also unplugging and re plugging the headphone jack "fixes" the issue as well. I'm pretty annoyed by this problem.

audio hiss after 4.4.2 update.

<<SOLVED>> The moto G Opamp is not very efficient. It struggles to go down to 2Ohm stable. This means average earbud type headphones rated at 16Ohms. will have hiss and other artifacts. Higher impedance headphones. 40-70Ohms have much better sq. Much above 70Ohms and I suspect the Moto G won't be powerful enough to drive them.... so, that's the sweet spot!
Hey,
Since I updated to kitkta4.4.2 I notice there is a significant background hiss listening with headphones.
As soon as you use an app that activates the audio jack the hiss kicks in, it is constant, not volume dependent. If you turn the volume down to zero, but the app keeps the sound output active the hiss remains.
when the app is closed, the hiss abruptly stops (presumably when the sound API deactivates the inbuilt opamp to save battery)
I'm about 90% sure this wasn't present under 4.3 or was far less noticeable.
I'm not being picky either, this is bad enough that it would make using the phone as a walkman at a low or moderate volume unpleasant. From experience I'd estimate the hiss at approx -20dB.. this is similar to the hiss you would hear from your average desktop PC fan at idle under your desk..
can anyone test this too, on 4.3 and 4.4.2?
Oh, and use earbud headphones or good closed cup ones. Open phones, unless you are somewhere very quiet won't give a good idea of the hiss..
thanks
Can confirm this on 4.4.2, too bad I didn't see your post before updating, as I don't really remember how it was on 4.3 :/
You don't actually have to use earphones, it's noticeable through the speaker, too (well I'm in my room alone and I put my ear close to it). However, I wouldn't say it's very significant - when using earphones I can hear it when muted, on the 1st bar after mute; on the 2nd you can't really say if you hear it or is it your imagination; and on the 3rd bar it's unnoticeable.
I can't notice any hiss in 4.3, even if I use a headphone amp. No clicking sounds either when the opamp turns on.

this is what I was worried about. I didnt notice any hiss before either, and I had it connected to a car stereo so would amplify the issue (if it was there).
maybe something did change in the audio settings/drivers then. I have already tried dissablying all the dsp stuff with no luck, still the hiss and click when the opamp switches on/off.
Maybe it was there before though, and it's bad luck with the phone, rather than the OS version.
I have got UK Retail 4.4.2 and I have tried to replicate this. I have tried YouTube, Spotify Play Music and TuneIn. I do not experience a hiss!

Under 4.3 to save battery I disabled apps I wasn't using, including the Audio Effects app, and google play. When you disable them it forces you to 'uninstall updates' which I didnt realise at the time, but I think may have been specific to the moto g, as you cannot redownload them from playstore, or update them.
Would someone be so kind as to upload the FULL apk of their google play and and Sound Effects, from their stock 4.4.2 build?
Im pretty sure this is down to the software API that activates the opamp. (as it is very distinct), it even happens when you activate audio by using the rocker to increase the ringtone volume!?!?!???
It sounds like listening to a really cheap mp3 player with a low S/N ratio...
** edit I mean 'Play Music' not 'google play'
Hi,
I actually just registered to say this was very much present on my moto g on android 4.3 and is still the same on KitKat. It definitely sounds like a cheap mp3 player. Does anyone know of a fix?
Thanks

Now this is getting weird. I think I'll install the ota to see how mine behaves. The G's audio quality decent enough imo. Probably above Android smartphone average. But what I like the most is that it's 100% silent, regardless of the volume setting, headphones or the amp.
Having said that, I will still get a USB DAC solution for it, which luckily has native support on both stock ROMs.

I don't see how this is on-topic, but of course, you can download the update either on Wi-Fi or mobile data.
I don't know what you mean with "hiss", but since I updated mine (today - uk), i have started to notice some "clicks" in musics, that i didn't have before.
I was using PlayerPro, turned off the equalizer, uninstalled and reinstalled it again, and it was solved.
Google music, had no issues.

by hiss, I mean hiss. It is probably around 18KHz, and is similar tot he sound of RF interference on a stereo (alsmost like the snow screen sound on a tv).
It is not volume dependent so it is defenitely downstream from the DAC, and must be the opamp or downsteram from the opamp in the phone. It is most likely from a poor ground some where in the audio path (assuming the opamp isn't awful, anyone know the chip?). It could be due to the single board set up of the Moto G mainboard design. I'm guessing here, but if the PCB has the audio channel close to any of the ground of power channels, this would explain my hiss. If it is built to tight tollerance, this could also explain why some people have it, others don't.
In laymans terms, I'm saying the audio signal is 'dirty. If anyone has every used a PC with crappy audio on the motherboard, they will know exactly what this problem is like. When no program is using the audio driver, the board puts the audio to 'sleep', when you open a program that uses that audio driver, the audio wakes up and you get some hiss, noise through the audio and pc speakers. This is exactly what I experience with my moto G.
if im honest, it's unlistenable, however I'm a bit of an audiophile so I can appreciate for most people they won't see it as a problem..

I found 4.3 to already be noisy with the hiss when using my earphones, which have a low attenuation and so even low volumes sound loud on them. To get around this problem I bought an attenuator which connects between the phone and the earphones. Then I set the phone audio to maximum, and reduced the volume using the attenuator. Setting the phone audio to loud means the hiss volume is low compared to the volume of the sound coming out of the phone.
This is the attenuator I use:

this is a possibility, but its not ideal... sadly this is looking like a hardware issue not a software one though as if it was software, I'd expect it to be upstream of the opamp. The fact your attenuator solution works, is more evidence this is a downstream issue . (as implification induced noise increases with the square of the volume (assuming a logarithmic volume scale))
I'm on 4.4. I notice a slight hiss when music is coming out of the phones speaker, though its completely undetectable if the phone is at around half volume. No hiss when coming through headphones.

Please can you test something, with some sensitive in ear headphones (or in a quiet room if they are normal headphones.)
>Connect headphones to phone

>turn the phones ring volume to zero
>you should hear silence.(regardless of what headphone volume is)
>On the home screen, Press the Up volume rocker 3 times quite quickly.
>On my phone, the headphones go from silent to Hiss, then I hear the 'Beep'.....'Beep' of the volume increase on top of the hiss. Wait 2 seconds after the second beep and you hear the Hiss abruptly stop, and you are back to silent.
I have this problem with all audio activity on the phone, but the ringtone volume trick is the easiest way to demonstrate it.

Or even easier, just press the volume down or up button once in any direction with headphones plugged in. Regardless of what it was set to and becomes set to, you will hear a faint background hum/hiss be emitted through the headphones for a second. This is fairly normal on any phone and even most audio devices. I don't know what you expect really in a smart phone that costs £129 in the UK. It is a compact environment to build so much electronics into and will never be a hifi device.
I tested with 3 phones on my desk right now and they all have a hiss when you first do something to make audio come through the headphones like quickly play and then pause a track. In fact, one phone (Samsung Galaxy Ace Plus) has not only a hiss, but a screech/high pitched whine as well. All of these "noises" that are detectable, become undetectable when volume of anything is turned up past the first or second bar anyway.

This is a fair point, and I agree is not surprising given the phones price. I think the reason I have posed this question was to a) determine if it could be software related (4.3 vs 4.4.2) but It doesn't looks so. b) Is it universal, or could be a slight lottery and maybe my phone is worse than others. As some people say they definitely have no issue. (granted it could be subjective)
Also, I would say, although it is present in most devices to some degree, it is noticeably worse on this phone than any other I have had. Multiple sony erricsons, galaxy Ace, Nokias.. And my last phone Galaxy S2 had extremely clean audio production. (i compared directly with moto g).
I do concede I am an audio snob though, so don't like listening to poor quality. I never really expected to use the moto g for music, but would have been a nice to have.

Yeah, it seems to me too that you are a bit more on the audio than most people
By the way, I was wondering up to which levels can you really say that you hear the hiss? As I've said before, for me it's definite hiss when muted and 1st level, weird feeling on the 2nd and I can't hear it from the 3rd.

Depends on the music. pop music which has a lot of mids and highs, the hiss isnt noticible from notch 4 up maybe.
Quiet music, classical, R&B & hihop with a lot of bass beats but not many highs, you can hear the background his up to maybe 2 notches off max. But its acceptable from maybe half volume.
tbh it's more of a shame than an issue. I didn't expect this to replace a decent mp3 player, would just have been convenient is all.

Buzzing distortion sound through earphones when download of sth is in progress?

Hi,
I've been experiencing an issue since I've had this phone for a little more than 1 month.
If I'm wearing my wired earphones (don't have Bluetooth ones) and the phone makes use of the network (as when a video or a song starts to load) I can hear a buzzing distortion sound in the background as long as the download is in progress. In fact, I have a network speed meter on the status bar and when I'm not doing anything the phone jumps from OB/s to 1kB/s every once in a while (which is normal) also resulting in an audible hissing sound in the background through the earphones.
What the hell is this? It's pretty annoying especially when a YouTube video begins to play.
Nothing here
Yup, pretty normal when poor isolation of RF is done hardware-wise. There is probably nothing software that can be done about it except for better frequency filtering on hardware/driver side.
You pretty much have to live with it; back when I still had my Axon I barely noticed it and only when I was lying in bed right before sleep.
I doubt @front firing speakers does not have it on his phone.
You have to be in a very silent environment and set the volume to really really low to be able to notice it.
The Nexus 9 tablet is also very prominent in this regard, or the Nexus 7 2013 speakers (not headphones). A variety of devices have this issue.
What you could do to confirm it is hook up and oscilloscope to your 3.5mm input jack, play a video at exactly ZERO volume and look at the frequency of the signal you got there
