Strange soundbug with headphones (N7 3G) - Nexus 7 Q&A, Help & Troubleshooting

Hey guys
I already stated my problem in the slimbean ROM thread:
IchStelleDummeFragen said:
Sound works fine from the speakers, but via headphones it sounds like only a few "layers" of the song are played, dont know how do describe it. In some songs you cant hear the voices or instruments are missing. Tried different players (stock, gmusic, poweramp) and headphones, problem is still existing. Not sure if its because of the Rom but i cant see any other thing causing something like this.

I'll try to describe the problem more detailed:
First of all the sound via headphones is pretty quiet and sounds strange, especially in music with electronic elements.
Its like some "layers" aren't played. Result is some instruments or the voices are not existent or so quiet you can't even hear them.
As already stated I tried several headphones and players, nothing is working....
The same music files are working perfectly on my sgs 1 or my PC, so they can't be the problem.
Im not using any further mods except SMS/MMS.
Could it be a hardware defect?

Went to this ROM, problem is still there
help me please.

Now on paranoid android without any mods, did a full wipe and everything, still this bug...
Hardware defect?!

back to stock - working perfectly fine
seriously - wtf?
no idea what went wrong, maybe a fail while flashing or something...
this just sucks because i want a custom rom...

I was going to say thew headphone output on the N7 is pretty good aside from the annoying noises in quiet passages caused by CPU scaling (?). I even run no eq with my TDK BA100s, unlike my HOX which sounds like a crappy transistor radio. Damn you, hTC...

Strange problem with MP3 playback - missing vocal

Hi.
I have a strange problem with MP3 playback with some songs; when listen on headphones, everything is fine, but when I listen on speaker, some songs are missing vocals; you can hear just instruments, and veeerrryyy faintly vocals; like they are in other room. But when I connect headphones, that same song sounds OK. And I have that issue with just few songs; others sound OK on speaker and headphones, and they work fine on computer.
I have tried with stock player and winamp, but i got same problem on both of them.
Wow. You have a one of a kind karaoke phone ! Sell it to someone in Japan and buy 10 new phones. Other then that I have no idea except install a different Rom to rule out software problem

Hehe; it would be nice if there was a switch to turn this on or off and if it will work on all songs Then it will be nice feature
I didn't change my firmware, so I still have 2.1 stock JM1. And this problem was present from first day, but I didn't care about it, because it was present only on two songs that I have.

Sound too quiet, try this.

Hi all,
I've always felt that when playing music on my DHD that it's too quiet, when I've listened to music through my headphones I would say it's acceptable however when I've plugged my DHD into a HiFi or into my stereo in my car I could crank the volume to full control without it been deafening. I happen to find a fix yesterday by accident, I had my DHD plugged into my car stereo and the phone rang, I pulled the audio cable out and answered the phone, when I was done I put the cable back in and immediately I was like WTF just happened now, the music was much louder than what it was before I answered the phone, I would say it was about 30% louder.
I tested my theory by stopping the music and unplugging the cable, plugged the cable back in and started the music, while it was playing I opened the phone and simply dialled any random number and ended the call immediately, when it went back to the music it was most certainly much louder. I've tried it several times now and every time it makes it much louder than what it was before I make a call, I can now no longer turn the stereo full blast as it is simply too loud, just by turning it up to half way I would say it's the equivalent of what it was before when I had it turned up to the maximum.
I'm using Poweramp and I don't know if it's got anything to do with that, I will test it with the built in music player and see what it does. I originally downloaded Poweramp as I thought that the built in music player may be the problem.
i'll repet what you do and post some results... really want a louder volumen in headphones. I plugged my headphone in a Wildfire and it's incredible louder, no talking about an ipod! last week in a party i was ashamed when my friend put off his $50 cell phone and i plugged mine on stereo, so low volume....
wtf, that's true.. really don't understand what the phone turns on!! probably the same thing that volume boost turns on!!
Aha that actually works

Good news, it must be a software bug with the volume control.
works here too.. atleast on poweramp and soundcloud, didnt hear any difference on spotify

let's hope someone let this bug permanently turned on, with no call trick...
Haha! Tried it myself, and it works! Awesome!
I found using shazzam or sound hound while music was playing caused it to go louder. Seems to be when the mic is initialised. Noticed this two days ago

Interesting find.
I've noticed a couple of ROMS which suggest better audio volume by 20%.
For example this one. (Speaker Boost +20%)
So somehow, somewhere the bug or issue has been fixed or improved.

Not really, i'm using that rom right now, and what it makes is improve SPEAKER volume, not from headphone. I made my tests in Android Revolution rom and can confirm that headphone is as quiet as stock rom, and it is improved by the "call trick"!
Thanks for sharing! I was experimenting a bit, and it seems like the simplest way to boost the volume is to make a call while music is already playing. The call MUST connect though, or the volume will revert to normal levels. Tested with Winamp.
Maybe have one of the dev's ask to look into this.
If this is different from the already increased speaker volume output, it probably is a bug that can be fixed / feature that can be 'un-featured'
works fine
I had similar experience with my laptop. When listening a mp3 file, the sound coming out from my laptop seems like no effects, standard sound without bass and treble effect. Have to play a movie file first together and stop the.movie make the song hear with the effect.
I believe this issue coming from my sound driver. Using another OS in same laptop. The sound play normally with no issue.
For our Android, it's about the sound driver too?
well well, i just noticed that in the Android Revolution 4 (leaked gingerbread based), the sound is improved by default, no needing the call workaround, looks like HTC fixed the strange bug for the next version...
i just wanted to share!
edit: if someone could try to confirm it, i'll appreciate! =o)

I had the same problem, go to the Market and download "Volume Ace".
MarkieSA, you're an accident hero.
I noticed sometimes my DHD volume suddenly were loud . If I restart the phone, it will go low . I couldn't find out how to make it loud again until reading your post. I'm using PowerAmp too . I think it plays a role in this case.
Thank you for this great finding.
Really useful little trick for 2.2 users, especially for peeps using stock ROM's without the 20% boost via custom kernels. I had tried some of the volume boost type apps before rooting but all they do is invert the phase of one of the stereo channels. All this does is give you a very tinny mono output which is no use to say the least.

[Q] Headphones problem

Has anyone noticed a problem with using headphones? I have tried 4 different pairs and only managed to get 1 pair working properly. The problem is that when you plug the headphones in the small headphones icon appears in the lower right hand side but when you play the music it comes through both the headphones and also the speaker. It seems to be the headphones are not seating properly.
same problem!!
yess i have the same problemm!!!
i realised that to fix this problem, you have to plug in the headphones while firstly playing any songs through the tablet speakers, then it detects there's headphone plugged in.
This is issue is really pissing me off!! i hope they fix it asap!
yes i had that problem and felt like an idiot when i finally realised that i was sharing my music with everyone on the bus!
very weird problem which has stopped me from listening to music on my a500 even though the audio quality is superior to my Sony Ericsson X10 and my HTC Sensation.
Thanks for the tip - I'll try it out tonight!

this trick works for me too, but only while the audio is playing through the specific app. if i stop music while doing this trick and change to video it out puts the video out of both speakers and headphones again.
It really has nothing to do with the jack seating, it has to do with the audio mixer and the jack detection.
it should be fixed eventually (hoping with ICS) but for now I have to take my headphones off and check the output like a weirdo anytime I want to switch apps using headphones.
Hi, I have also this problem but I noticed another strange thing : when you listen to a track using headphones the stereo image looks moved slightly to the right, it's not well centered. Is it only a problem of my A500 or is it general ?
Thanks

Are you guys using non-stock ROM or something? I am on stock 3.1 and I am not having any kinds of issues with it, headphones work just fine and the stereo image is as centered as it should. Or maybe it's your headphones, have you tried with other devices?
I'm on Taboonay 2.1 and i can't remember noticing it when i was using stock rom. I only noticed it because i felt the slight vibration coming from the speakers. I have got 1 Set of headphones that work really well with it and it only happens with my other headphones which weren't exactly cheap (typical) but they all work on everything else i plug them into, so i think it's more to do with the seating of the headphones rather than the rom because i've got a pair that work fine, although i now have some doubt so i'm going to try them all out again to make sure
Same problem here, with Taboney 2.1 and different head phones.
Hi, just upgraded to 3.2 original and now everything comes out in mono. No stereo from headphones. Anyone having the same prob? Wow, things are getting even worse....
Ramp
I had this same problem too on stock HC 3.1
The trick works for me; but is rather annoying trying to drive and play music at the same time
I have recently changed to Lightspeed ROM with Thor 3.7 (the rest) kernel and have not experienced any sound issue yet =]
I have some problems with the last Tabooney 3.2 ROM and headphones too.
Sound goes through headphone and tab speakers.
I noticed that if I unplug and plug headphones twice or three times I could only have sound into headphones and works well.
I never used OTA ROM so, can't say if it works well with it, but there is a prob with Taboonay's ROM.
I can't post in DEV thread (regard to my posts count).

Note 4 earphone jack question/problem. Help/advice wanted for troubleshooting/fixing.

Hi All.
Have not posted on here in a LONG WHILE, but here goes:
Recently I got my hands on a Note 4 (SM-N910S) (its one of those Korean models that have LTE-A X3)
and when I first got my hands on it it was fine and all, but after a while, whatever earphone I plugged in, it sounded weird, and the only solution was to bias the sound to the left (in PowerAmp, my music app of choice) which somehow centered the sound but it sounded like it was on Mono the whole time as I could not hear the whole range of speakers being used.
Last week I dropped by a repair center and asked for a jack replacement, they charged me 10$ for the part and about 20$ for the labor (I was busy so I said hell with it). After I received it back, There is still a problem
Now what happens is the sound appears to be very muddy, and if, for example I was listening to something with a large variety of sound, like heavy metal or EDM, it sounds really drowned and far away, and the bass seems non-existent at all, and the speakers which seem like they are there for bass and/or sound directed to sort of rear-way are not working at all, and the treble side of things seem very harsh. When I bias the sound to the left now, what happens is the volume seems to decrease!
So before I spend any money on this thing, I want to know if you guys think I still need the jack replaced (this time by me maybe) or if something else is wrong, because I use this phone heavily for music (nearly 30gb worth loaded on it, used very heavily, on the daily) as well as for entertainment purposes, so it is very important to me I get this thing on track.
Any advice is welcome, as I am also quite desperate to solve this issue.
Oh, and the phone is pretty much brand new, got it on christmas/januaryish, and has never been damaged or used hardly, its only been rooted, and is currently on 5.1.1
IF I did post this to the wrong section, mods I am sorry, please feel free to move it.
Thanks in advance to any help. :good:
Have you tried adjusting the sound settings on the music player app? Does this happen with other headsets?

Yes I have, as I said, ive tried multiple headsets, and ive tried all the settings and multiple apps. I can tell it is a hardware problem since when I send the sound to the left earphone, it only lowers the volume, but the sound doesn't move/bias.
Why not try a pair of bluetooth headphones. It will establish if there are problems with the sound DAC of the board or if it is a hardware fault pertaining to the headphone jack connectors. If its the sound DCA it might also go away with a reflash of the factory image through Odin.

aliexpress android 5.1.1 rkpx3 strange sound effet that only affect some apps

Good day everyone. I bought one of these receivers without too much research, not knowing there was a big community. This is a true no name...not a joying or Wilson but it looks like those brands.
Everything works find except for one fatal flaw that makes it unusable for me... hah!
Music through USB (flac,mp3,wav) or most apps (soundcloud,VLC) seem to have a "night mode" or "equal volume" effect on music like we would see on home theaters. Anytime two or more sounds play, the loudest sound(could be anything, like a cymbal) will play lower than it should and all the other sounds (voices, instruments) that were already playing before the loud sound will then sound much lower in volume until the loud sound goes away then the regular sounds play louder... It makes it impossible to listen to music.
The strange part is this doesn't happen through the radio nor through the CD (Different apps). I've tried a bunch of music apps and they all sound bad playing source form usb.
Somehow Netflix sounds fine though...
Music sounds bad through Bluetooth from my phone too accept if I stream them with my NAS's Qfile application... then it sounds fine somehow... I don't get it. Clearly software related.
Contacting the seller is no help.
Anyone else ever encounter this? Fix or suggestions?

See my development thread, I've become an expert on this thing.
Do a factory reset. Otherwise, you will have to wait till I port it over to Marshmellow.
Setting icon, then more settings, then back up reset.

Thanks, I've done that already(twice) with no affect.
I assume you mean the RKPX3 / Rock Pro / RK3188 / RADXA Android Car Head Unit - Master Thread ?
I'll have a look.

Any idea what is causing certain apps to get that strange processing but not others?
