Hi guys,
I've found a very interesting sound effect on my O2 XDA Mini (=Magician). I've been having the phone for a few days only, but right from the very first calls I noticed that the speaker creates a very high frequency continuous beep-sound, not loud of course, but crazy high, something like the well-known side effect of the old CRT TVs. At first I thought it is produced during a conversation. Then today, I held my phone to my ears without any calls, and guess what: the beep is there. :shock: It's produced always!
I started to look around, and had a hunch that the LCD backlight can be the problem. I played a little with the backlight setting and found that I was right, the sound is poduced only when the light is set to low. It's loudest at the first notch of the light slider, and gets more and more quiet as you set the backlight higher.
Now I wonder if it's a special problem with my phone (like some bad quality filtering somewhere in the power electronics of the backlight system) or if it is the same with your devices.
Please try it and post your comments. Listen closely! And try both ears (not kidding), the sound is very quiet and very high in frequency, so your ears may not be up to the task to pick it.
Have to be honest I can't get a quite second at the moment but I'm pretty sure I've noticed this noise before as well. Another noise which can be irritating is the GSM radio module and it's intermitting buzzing (a quiet version of what you hear when unshielded speakers pick up your signal).
So basically I'm not sure but I think it's a generic issue with the backlight
Hi,
I found that too....
it's quite irritating as it looks like an old TV turned on.
I hope that won't be a problem to our ear in the future

I recently bought an EM-ONE here in Japan and so far I am quite pleased with the device. It has a few shortcomings, but nothing too serious apart from one bug that is really annoying: When the device is turned on there is constant white and high frequency noise coming from the speaker. Even if I mute them the noise is still there and quite perceptible when the volume is tuned low. This turns out really bad when using the device's microphone as the noice gets recorded as well which puts a lot of static on the line. My question would be if there is anyone else sharing this problem (maybe on another device) and if there is anything I can do about it. Any help will be greatly appreciated!
Hi,
I'm new to this forum so please be kind
When I listen to MP3 I hear a high pitched whine as the player switches between songs. It only occurs for a second or two right before the music starts, is followed by some lower pitch crackling and then when the track is playing this high pitched noise is absent.
It's relative volume to the music is loud enough that it's pretty irritating.
Is this normal for the Xperia or should I be getting my handset replaced? It's an UK O2 xperia with the latest "leaked" rom loaded and using AKG k414p headphones
Thanks

First test it with different headphones. If it still occurs then, try another ROM.
This is not a generic bug, as I don't have the problem myself, nor have I seen anyone else post about it here (and trust me, if the problem arose more often, people would have).
So, test a few things and then come back to report =]
thanks
I've just checked with another set of headphones and I can still hear it
The problem occurs on both the original o2 rom and 1.03.931.8 which is the latest that i'm aware of.
I'll see if I can think of anything else to try.
Thanks
I think it is a general bug.
I know, my old SE W850i wasn't made by HTC, but it had the same issue.
It looks like a pink noise, and you don't hear it for very long, because after a few moments (1,5 sec or something) it just dies.. (Like a gate is fading it out)
Since it you can only hear it in a very quite place, it doesn't matter to me..
I'm not gonna use my X1 in places where I need high dynamics..
Have played about with it a bit more and found that the issue isn't as apparent at all when using the player on the Media Panel. I was previously using Pocket Player.
Hi!
Just to confirm: I Have that high pitched noise too. Just two seconds before next track starts.
No changes between R1AA and R2AA. Actually using Pocketplayer as SRSWOW HD disabled Windows Meadia Player Volume Control. Music on 8GB SDHC Card.

I got my xperia replaced and it would appear that my original handset was faulty. With the new one i can still hear a very quiet and very high pitched whine when it loads up the next track but this noise is in conspicous enough that i can live with it.
The original handset has a much louder high pitched pink noise and also noise like static, so if you're experiencing something like that you should get your handset replaced
looks like i spoke too soon.
This handset has also developed the popping static noise that the previous unit had looks like this could be a generic Xperia fault. It really is quite odd that it would work fine for a day and then develop the same fault as the previous unit.
I experience the same high pitched noise in my swedish X1. It seems to get a little less noticeable when using bigger headphones, but with IEMs it's pretty pronounced but yet acceptable. Another thing that is much more annoying is the cutting out in the beginning and end of songs. Is there a way to get gapless playback in TF3D mode (skinned wmp?) on the X1?
:-O
amazingly.... the file seek noise has been eliminated after I installed Touch-it v7!!!!
I'm happy with the x1 as a music player now but it does beg the question "why can't SE sort it out!!!" as it's evidently more likely a software issue rather than a hardware issue.
ok .. i like my x10
but i always ask about this issue is it hardwer or softwer
can any one help .. .
thx
software issue
When you say sound do you mean call sound and the Mic picking up lots of background noise? That seems to be a big thing for me and its quite bothersome
Sent from my X10i using XDA App
The sound on mine is horrible too. I really hope it is software but I have a hard time seeing that being true.
I always get told how bad it sounds when I talk to people on it, sounds fuzzy apparently and I always have a hard time hearing people some times.
Please be software!
i mean by sound of the x10
te general sound
for me i care about the headphone or when i use the phone aux with my car
and ply some music the sound is low .. to low
even when i walk around with earjaks .. i can hear everything around even if the level is the most ....
so i hope its softwer thing
Yeah that is also a bad feature of the phone. You'd think Sony would have tried to incorporate their Walkman expertise in this.. but yet Walkman isn't even a name anymore. Just forgotten.
Also if you put the volume too high it gets crackily.
The problem can be either software or hardware. If the DAC they have has terrible resolution or their algorithm for sound isn't up to the task the sound will be bad. Or even under-driving the speakers.
But anyway, I've noticed the in-call speaker for the x10 is very directional, meaning it doesn't let sound radiate out from what I can tell. This might sound silly, but it worked/works for me, just slide the phone around on your ear a bit until you find a "sweet spot" that maximizes the sound.
Mine was relatively low before but now I can hear pretty well. With that said the volume is still pretty low regardless.
EDIT: The x10 uses a separate speaker for audio while not in call, its located at the top left side of the phone. This speaker probably suffers from the same problem as the other one. Except this one is made to radiate.
HI there guys.
Brand new to this forum.
I've searched for days and I'm unable to find a solution.
I'm experiencing a crackling or a distortion on phone calls at certain volumes. I noticed it with certain pitches in peoples voices it would cause a vibration in the ear speaker and some distortion in the sound. Kind of like the speaker is being over driven or has too much power going to it. It usually goes away if I turn the volume almost all the way down, but this is obviously not a practical option since I'm not always making phone calls in a dead silent room. The speaker phone works fine. This only happens when I'm using the earpiece. Is this normal? Is it related to the camera autofocus sensor rattle? Are the sound vibrations from a person's voice enough to set off the rattle? It's really annoying as I tend to make phone calls a lot and I don't like using speaker phone or a headset. Does anyone else have this problem?
From what I can tell, it happened and was normal in the S4. (http://forum.xda-developers.com/showthread.php?t=2280930).
Please help. Im deciding if i need to return it.

It's too bad that you didn't describe it in more detail.. i.e. give us steps to replicate it. A recording of the distortion would have been helpful too. I haven't noticed what you describe but it sounds like the gain or auto gain is too high and your earpiece speaker is being overdriven.
There is a gain setting in the service mode menu but first you need to distinguish an app issue or possibly damaged speaker before messing around in the hidden settings. See if you can find an audio app that will give you a wider adjustment range for your system volume and gain.,

Thank you for the reply.
If you go into the service menu, the go into the low frequency test. At 100hz and 200 hz there is a little bit of buzz in the headset reciever unless you really push it against your face (which i assume kind of tightens the spaces in the plastic and prevents whatever vibration in the speaker is occuring).
Hmm.. the vibration is akin to as if you were speaking into some cellophane wrap; like some film (maybe for waterproofing) is covering the speaker.
Oh. It's also worth noting that I cannot replicate the issue on Skype or Viber. Those sound crystal clear.
Bump. Anyone?
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
