[Q] Acid Audio or similar - Nexus 4 Q&A, Help & Troubleshooting

I've been using Acid Audio with all my CM ROMS from when I had an HTC Sensation to my current Nexus 4.
The sound improvements have always been amazing.
My only issue is I've never been able to get the music lockscreen to appear when I have my headphones plugged in. They're present without headphones. This was an issue on my Sensation as well as my Nexus 4. I assume it might be a CM issue?
Has anyone else experienced this? I've flashed all the appropriate attachments as well as followed all corrects steps. I've asked this in the Acid Audio thread in Q&A and main thread a couple months ago but never get a reply so I did not want to clog up the board beyond my initial post.
Does anyone have experience with flashing them onto CM roms on the Nexus 4 and have everything working properly?
If this is a known issue (which I was unable to determine from scouring threads and doing searches), is there a recommended Audio enhancing mod for the Nexus 4 that gives similar results?
TIA

Audio enhancer thread

Hello. I am interested in violation the audio on my 7, and saw the thread about the beats audio driver. I already have that driver installed, but not the other drivers that go along with it. I'm running stock rom, and wanted to know if I could install it even though I already have the Beats driver installed.
Also, after reading several posts, it seems that this hack has more problems than most. I'm happy with the stock jelly bean rom, but am not happy with the audio, but I also don't want to create problems that I have to deal with.
Any suggestions, or insight into whether I should try this or not?

you could try a customer kernel like trinity and try using a USB audio DAC.. i have a USB Dac on its way to me over the next week or so, really looking forward to trying it out. You have to boot the nexus 7 with the DAC plugged in.. but apparently it works.. looking forward to listening to FLAC files through the DAC on my ie80s'

Look around for it. Dev has free on his site or pay on play store.

Extremely low microphone volume during calls

Callers at the other end have difficulty hearing me, and I've never been able to find a solution. At first, I thought it's the ROM I was using, but after flashing the stock rooted ROM, same problem. I'm using the correct baseband. I'll do a test tomorrow, returning the phone to factory condition with the latest images from Google.
Has anybody gotten this problem and was able to fix it?
Update: Back to factory condition. Issue still isn't fixed.
Newer update: Called Google Play Store via this number 1-855-836-3987. They'll be sending a replacement.
Bump. No one else has had this issue?
Bump.. Same issue here.. Stock unrooted

While i am not stock, I did notice this one time with my phone... like extremely LOW to the point i was pressing the phone HARD against my ear to hear.
Solution? I went ahead and flashed Paranoid Android 3.56 and flash the Louder volume MOD in the themes and apps section. That fixed my issue, I also know that not all of you will want to root, and that this SUCKS. but try to restart the phone.
Just root guys, this phone was made for that

Oh actually the issue I'm talking about is different. The ear piece volume is fine, but whenever I talk to someone on the phone, they can barely hear me unless I use speaker phone. I was actually using Paranoid Android, and I was being told I can barely be heard. So I flashed back to factory to see if it was a ROM issue. Sadly it wasn't.. On factory ROM I can still barely be heard.

I'm having the same problem as well. Just received my Nexus 4 last week. They especially can't hear me if I'm speaking to them through my car speakers (3.5mm connection, not bluetooth). Wasn't a problem at all in the same vehicle with my Galaxy Nexus. Please let us know if the replacement worked better.

I am also having the same problem...my girl keeps shouting that she can not hear me..at first i thought some problem with network but than some of ma friends said same thing...whats the option now..?? i am from india and i imported it from US so cnt send back there..is anyone found any solution..??
I tried using headsets and the results were pretty much better..
Wish I could help. Just had to RMA mine today. Completely stock, no mic. Works when plugged in, sometimes, but for the most part no audio. When it is plugged in, the wife says I sound like I'm trapped in a bottle lol echo and static.
I had the same problem when I was running full stock. It was really annoying to hear "I can't hear you..." every other sentence.
This won't help if you do not want to root or run custom ROMs but since I switched to PA 3.56 and Matr1x kernel the people on the other end of the line haven't been complaining. I imagine for whatever reason it was fixed would apply to most custom ROMs and Kernels. I'll actually test this out this weekend and edit my post afterwards.
Edit: I made some calls to friends on PA/Matr1x/Radio .48 and everything seemed fine. I flashed full stock and called back the same people and only one person said they heard a noticeable decrease in the quality. That person also knew I was testing different settings on my phone so maybe they were messing with me.

Bumping an old thread ...
So my gf started complaining that she could barely hear me when I was using my Klipsch S4A headphones to talk--while in the car and in a quiet room. I was on CM10.1 at the time and I had read complaints from others with the same/similar issue on other ROMs, even stock/unrooted. I chalked it up to 4.2 and hoped 4.3 would fix it.
It appears that isn't the case. I just sacrificed root so I could flash a clean install of 4.3 (new bootloader and radio included) hoping it would at least mean I could have normal conversations with my gf again while the devs cook up CM10.2. How bummed am I to find out that the issue persists. I just called her from my office with my headset on and she said I "still sound far away." This is really frustrating. I never had this issue on my GNex.

I wish someone comes up with a solution for this.. I was hoping 4.3 would solve this issue also. Some say its cause of the noise reduction, isn't there anyway we could disable noise reduction?! I remembered I had that option on CM10 my i9300 but not on nexus 4 build.. This is really an issue for me since i always use headset for phone calls.. I was wondering if the original Nexus 4 headset would solve this issue.

Hi guys,
i found 2 "solutions" which didnt work for Nexus 4:
1: typing *#*#3646633#*#* into the phone to enter the engineering mode. "Should" work for all Android, does not for Nexus 4
2: the App "MobileUncle". Does only work for MTK Chipsets (Nexus 4 has another one)
my question: is there something like the Engineering mode for the Nexus 4 ?
Same issue on Nexus 5
FYI, the nexus 5 has the low input volume gain when using 3.5mm headphones with inline mics. I don't understand what LGs problem is with 3.5mm connections or why it was never tested.
started a discussion on in here
Any solution yet???
I have the exact same Issue, Android 4.4.2 and the issue is not fixed weird that only Nexus 4 has it. I am like you trying to find an app or a way to work around the issue, tried to install other ROM using rom manager and phone when SLOW as heck so no idea how to fix it yet, loud speaker to every single call is not the way to go

Occasional Audio Stuttering in KitKat

Hi Everyone! So I've been presented with this problem as soon as I flashed the factory image of Kitkat 4.4 on my Nexus 4.
Audio stutters momentarily on random occasions, whether its audio or video playback.
So to solve this, I flashed GNOME II PAEK 1.1 ROM which is based on KitKat 4.4.2, still the same problem.
This never happened on 4.2.2 or 4.3, we did have deadlocks on 4.3 but never audio problems.
Lately, I've noticed the audio stuttering when I'm surfing the web using built in Chrome and the other time I noticed when I turned on the WiFi using the toggle in quick settings.
Some fine mess the user is in these days. I wonder what google has been thinking lately, don't they test the software properly before the release anymore?
I would like to hear your opinion, has anyone else noticed those slight stutters?
Regards.
P.S I've searched over the internet and many people with different android devices are having this problem on KitKat.
I guess it is part of the "DSP Tunneling" feature that puts more parts of audio processing into the DSP instead of the CPU.
It might cause some issues right now, but in the big picture Google is making Audio processing more battery friendly.
So i personally support it and hope they do not just revert it back to the old way. It could need some improvements, no doubt they will come time after time.

If its battery friendly, it could be good, but the users needs a fix soon.
Mainly because not everyone has the time to root their device and flash previous Android version after the update and those who choose not to update, they're stuck with annoying update reminder(talking about the general users here).
I'm all for the improvements but not at the cost of broken features. Besides, I've been monitoring the battery drain manually on stock and custom ROMS and I didn't notice much noticeable change. Lets see what happens in the future.
Pretty sure audio tunnelling is Nexus 5 only

Bluetooth audio quality sounds distorted/fuzzy! [4.2.2 Stock Firmware]

Hey,
I'm having annoying problems with the bluetooth audio. The audio sounds distorted/fuzzy and is very easy to hear in certain songs
when the chorus or similar kicks in. I used the same headset with my Xperia Z and there was no audio quality problems.
I have also tested other bluetooth devices and its the same stuff going on...
Here is the funny part - when I flash CM11 and try the bluetooth-sound, the quality is perfect!
So I'm pretty damn sure its an software releated issue... I could just use CM11 ofcourse but the problem is then I miss out on other stock features I like
One song that shows this audio problem very clear is: Papa Roach - Leader Of The Broken Hearts. Spotify link here!
I've also tried to mess around some with ViPER4Android but with no good results...
Anyone has any good ideas?
Nobody has nothing to say on this matter? :victory:
I agree. Stock Bluetooth was terrible. Been using Viper for a while now... It's very good, when it's working. Even as a system app, it's being stopped and then it restarts a couple seconds later. Enable aptx in terminal and see if that helps. My head unit is old, so it did nothing for me.

Still have this strange high-ends distortions with/without ViPER, and it crashes all the time as you say.
My LG G2 original box says phone has Aptx enabled? I don't know if it matters though, my Sony Smart Wireless headset Pro (MW1) doesn't have Aptx support. However MW1 sounded great on Xperia Z and other various phones so I blame LG for fu**ing up the bluetooth drivers xD
My best bet right now is hoping for the 4.4 update to fix this problem. If not - this is a dealbreaker (change phone) to me because I listen to music via bluetooth all the time!
Crashes is a pretty song word. I'd say it's being stopped by the os. I've been having better luck with Viper audio after changing some kernel settings. Interactive Gov, read ahead buffer to 2048, and min frequency at 628. Viper had an update last week also. I've read some irs convolver settings don't like being used as system app. Been using a thx convolver with good luck lately.

my bluetooth is flawless even without any tweaks (and judging by many threads here regarding it, it seems to be a compatibility issue rather than LG "screwing something up" ) but have you tried this:
enabling AptX codec:
1. adb shell
2. su
3. setprop persist.service.btui.use_aptx 1
check that property was changed:
4. getprop persist.service.btui.use_aptx
you should get "1"
reboot the phone and check bluetooth sound quality.
to eliminate Viper being killed by the system just make it a system app and make sure you followed the installation instructions (including the build.prop tweaks if necessary).

A compability issue IS something that LG screwed up. This is the first Android phone I have with such useless bluetooth sound quality
I have tried to enable Aptx and got the result 1 but since the headset only supports A2DP it will not matter I think. I got ViPER4Android to work as well but the sound is still bad... I mean some parts sounds really good and clear but some parts where the high ends are kicking in loud the sound gets distorted
Still haven't solved this, good thing CM11 works pretty decent. It lacks some awesome stock features but the audio is nice so I can live with it
"I have a similar issue in my 2011 Hyundai Genesis Coupe. The static is only present during loud levels on songs, not at all times during the track. Seems like it is most noticeable on the higher frequencies also. Please reply here if your issue is the same.
I did not have this problem on my HTC One X in the same car.
I have searched all over Android and Hyundai forums and found little to work with. What I have found is that this is not affecting everyone, otherwise it would be all over the forums. I appears to me that it is related to our cars bluetooth receivers and how they communicate with the phone.
I found some posts from a user CBaronne where he had what appeared to be the same issue on another phone and modified the "Bitpool" value with good results. He wanted to do the same on this phone but the variable is buried in a system file and modifying it was beyond his expertise.
I have also flashed several sound mods with no success, as well as different tricks to ensure that APT X is enabled. Nothing has helped.
I think until we get a developer with this phone and has this issue there will not be any attempt made to resolve. You can always just buy another car..."
I have been posting this comment in several threads to try an get some attention on it. This issue is not common enough for it to have consistent comments or investigation.

Reading other Android forums and Hyundai threads it DOES appear to be a compatibility issue, meaning that it is about the combination of two devices, it does not affect every G2 bluetooth connection. From the first link I posted it DOES appear that if we can adjust the bitpool values of the G2 we could improve the quality.
I have this same problem with my vw Jetta. My nexus 4 sounded amazing and now this g2 sounds like sh*t.

Okey, so I finally got so pissed off about this - that I got an HTC One, coming with 4.2.2 pre-installed.
Funny thing is this phone had more or less the same bluetooth-audio problems in 4.2.2.
However when I did the update to 4.3 on the HTC One the sound quality became perfect! I also installed 4.4.2 recently on the HTC, but sound is still great whatsoever.
So if HTC didn't fix this in 4.3 by themselves, its probably a bluetooth-fix coming with 4.3+, which means ppl just have to sit tight for official 4.4.x or use CM11 meanwhile.
Offtopic: I don't really miss the LG G2 luckily, HTC One feels more premium in hand and the UI is very fast and well designed. The loss of better hardware specs is just some words on a paper. Hell, I would say the HTC One even feels snappier!
I bought a BT 'headset' type thingy from Amazon that has APT-x on it as my current one is old and it has always sounded terrible via BT compared to wired.
The list of all APT-x BT stereo headphones is here... APT-X Headphone list. I found another list, but, it linked back to each individual page on this list, lol.
The one I chose to buy, primarily based on price, but also on user reviews was this one... BlueAnt Ribbon
I didn't want a big 'Beats' type deal, so it had to be a small model. The only ones I could find to buy in the US at a 'reasonable' price of $24 was the BlueAnt Ribbon and the HTC bluetooth stereo headphones. The HTC cost about twice as much with shipping. Mainly because the product is not (yet?) available in the US and the HTC is shipped from Taiwan after buying on Ebay.
There is a really slick silver looking dealy, but, I don't have $120 to blow on something that will likely function in the same capacity, but, looks cooler. Maybe when I spend more time making money and less time trolling XDA forums I can buy them, lol.
i know this is dragging a old thread up a bit but im having the same issues with my sony car stereo, it sounds as if bitrate is low and when you hit a high point in song its distorted crackly and hissy
has anyone found any solutions to this on 4.4.2 or is cm still the only decent fix? i like the LG features but i think all the decent ones have been ported over
any help would be amazing

Extremely low in call volume. Files to edit?

I've been running OmniRom with PA full modular gapps for a while. Currently on 03/05 nightly w/Franco 203.
I use Viper4Android to adjust my headphones and speaker levels.
I have been having extremely low in call volume since 4.4 and I can't figure out why. No one seems to have an issue. I've played with adjustments in Franco's app as well as settings in Viper but it doesn't help. My music sounds great though and voice calls put on speaker are very loud and clear. It's just the handset speaker that's really low.
Previously on my Sensation, I could make edits TPA2051_CFG_XC.csv that would help. And in the Nexus 5 forums I see you can edit mixer_paths.xml to help as well but when I look at the Nexus 4's mixer_path, there isn't a line to adjust handset volume.
Is there a file I could edit to adjust my in call volume? Or any other way to fix this?
Edit: Forgot to include, I use hybrid radio 33-98 for LTE. I've tried other regular and hybrid radios as well and that hasn't helped.
I wonder how helpful this would be for you, but I faced problems with in-call earpiece volume. I had to connect my headphones, call a number, maximize the volume, remove headphones and re-test the volume without headphones. Apparently, I had noticed that it mixed settings of both the profiles - with headphones & without headphones.

Just tried it a few times. No go for me. Volumes for with and w/out headphones are at max. I tried lowering one and the other. Or raising them at different intervals. Still didn't help.
Thanks for trying though.
I actually have the same problem right now. I tired using a flash able zip. Which I have no idea where it is now but all it did was completely disable touch for me. I never tried ViperX but I'll keep snooping around and see what works for me and let you know

Nope. Sorry. I don't think many people are having issues. It might be hardware related but I haven't done a full format to test anything new out.
I update to the newest nightly like once a month and I don't make very many calls so it hasn't been detrimental to me yet.
I haven't seen anyone bring it up in the Omni thread though so I'm certain either a clean start should do the trick or it's hardware related and you'll need an RMA.
Hope you find a resolution for your issue! I'll definitely post something here if I ever figure it out on my end.
Same issue here. Occasionally I've fixed it between kernel or Rom flashing, but never found out what I did to fix and when I'd flash again it would go back to bad quality again. Sometimes I have to stick a finger in one ear and press the phone hard into the other ear to hear anybody

I'm a bit hesitant to flash something for the S3 onto the N4. Plus, the file in that zip you're referring to isn't one that's contained on the N4 in that directory.
Thanks for noting, though. Maybe I'll backup and try it to see.
