Poor audio quality - EVO 4G Q&A, Help & Troubleshooting

Just a quick question...installed KINGS rom and loving it! However, I've noticed when playing any audio now, the quality is degraded. Has anyone else experienced this? I tried installing the newest version of Pandora, but it didn't seem to help. Checked the forums for answers, but couldn't find anything. What say you? Thanks!

You can try getting DSP Manager to boost your audio.

Sometimes I definitely notice that different kernels affect audio quality too. I think some of them have various audio tweaks built into them. Perhaps trying a different kernel may have some affect on it too. I tried that rom for a few hours, but donn't remember checking the audio quality on it.

Pandora - Is there a fix out there

Is there anyone else having issues with the sound of Pandora using new ROMS. I tried uninstalling it, reinstalling it, made sure high quality was set, tried to look for the media setting in the build prop and change it but that setting disappeared a few releases ago, and have searched through everything and still have a hard time listening to Pandora in the car because of the quality. I am not saying it is as poor as it was when 2.2 first came out but it is poor. The voices are tinny and turned way up is piercing to the ears. Base is great! But that is it. Any help would be greatly appreciated since I got rid of XM radio years ago and am strictly using Pandora.
Use the modded transparent unlimited skip version in the transparent market thread in theme section its in the opening post with a link all by its self at the bottom. Make sure you delete all Pandora data and cache as well as removing Pandora. Quality is perfect. I'd link it but I'm on xda app.
Also don't update it.

If your running CM look to see if you have DSP Manager, and make sure it's not compressing the audio, or the equalizer is on. I had compression somehow turned on one time by accident. Turned it off and it was worlds better.
I haven't had an issue with the sound quality...I agree with Mithos, perhaps your DSP settings are off?
I have had an issue with Pandora over Bluetooth dropping out, though. Happens only on first connect, if I turn Bluetooth off and on again it seems to resolve the issue...
Nope did not have compression on and I have DSP. I also download slacker and it does the same thing. I guess since it is just me maybe there is osme other program that is causing the issue. Have no clue which one since it is pretty much stock

Just want to let everyone know, a while back I was complaining about Pandora and Slaker. I decided to try a differnt ROM just to see if it was an issue with 7 and it appears that it is. I loaded Nils' Business Sense and it sounds great. To me there is a big change and I am not sure what it is. I did try multiple kernels. The thing is it sounds OK in a headset or listening it through a speaker on the phone but putting it on the car stereo where you amplify the music you can really hear some sound artifacts.

DSP Manager for ICS Not Working

Has anyone gotten DSP to work on ICS roms? I'm flashing the CM9 DSP Manager, and it installs fine.
Opening the application up I'm able to select presets, turn on bass boost, etc, but the sounds effects to not activate (no change in sound). They say they're enabled, but they're not.
I've tried on ROMChicago, Darkside, BulletROM. I've tried on a handful of music players to verify they were not overriding the settings.
Please don't refer me to PlayerPro or a different app to improve my sound-- I've purchased them all and tried them all, to my ears, there's no better sound than with DSP Manager setup properly.
Thanks,
TL
Works find here with beats audio mod. Only works with stock music player.

So you can turn on a song, then open the DSP Manager UI, enable and disable bass boost, and noticeably hear the difference immediately?

DSP manager dynamic range
Hi,
I installed Darkside Evolution3 v7 ROM and I noticed that dynamic range really gives good results.:good:
When I turn it ON it works fine for a second or two and then the sound gets really messy.
When the volume is changed works again and in a second it switches back to a messy sound.
To listen I have to keep pressing volume buttons up and down.
have ay idea about this?
cheers.
This may sound dumb, but did you try adjusting the effects strength. I thought dsp wasn't working for me either, then I realize that it was set on slight. After I moved it to extreme the sounds are way louder.

Ya Ive tried that. when I turn it to the extreme the effect is different but the same revert issue comes within 1 second ov volume change.
But if I go up use max volume (15) it stays that way but the bass is too draggy.

I was just browsing through and found you're post. It's funny because I am having the very same issue with the Darkside Evolution3 v8 ROM. You did a wonderful job explaining the problem I was trying to put it in words but that's exactly what its doing. Turn the volume up it sounds great and then a second later you can hardly hear it. Some things I noticed, it only seems to happen with an audio jack headphones plugged in. I dont notice it with my car blue tooth. Also have you noticed a difference if you just turn off DSP mgr? I forced closed it and it was fine but as soon as I started that process again it had the same effect. It's quite annoying.

I tried force closing it and then the sound effect is totally gone and it sounds like stock player. The issue is only with the dynamic range filter.
if its turned off the issue doesn't come up. I was hoping to upgrade to v8 due to this issue and it seems that there is no luck in that as well.

Hey,
Found a solution to the dreadful issue. Install tasker and add a action which changes media volume
continuously one up and down will not effect your listening experience but will keep the effects alive.
hook the tasks up with a profile and you can make it automatic when the headset is plugged in.
I waisted whole day trying different versions of dspmanager.
Most of the files floating around just repackaged versions sometimes wrongly of basically 4 different builds.
I got 2 different packages... one is working fine with Pandora and everything else but GoogleMusic, the second is working with GM but not with Pandora... rest of the versions give either bad distorted sound or do not work at all.
I am on stock ICS. Which dsp you want?

[Q] Bluetooth quality issues?

So, posting here was a last resort, but I've exhausted all my other options. I'll try to make this as concise as possible:
I just did a bluetooth/aux input retrofit for my car so I can stop using CDs for music. Aux sounds crystal clear, bluetooth with my 2nd generation iPod touch sounds crystal clear, bluetooth with my Optimus G Pro has static, crackling at certain frequencies. Doesn't sound compressed necessarily, just crackly.
What I've done:
1) Hard reset.
2) Tried both the original 4.1.2 and the new "value pack" update.
3) Actually sent my phone back to AT&T and got a refurbished one in the mail.
4) Sent my bluetooth retrofit unit back and got a new one in the mail.
5) Rooted the phone, installed freegee and twrp, and flashed the hkfriends kernel.
None of this fixed my issues. When playing the same exact song on my iPod and Android phone, the iPod wins every time.
P.S. My friend's Verizon phone (I think it's a Motorola Razr) has the same sound quality issues. Not sure of Android version, though.
Music is the absolute most important thing for me, and if I can't get this resolved I will have to switch back to Windows Phone/iPhone, despite how much I love Android. I have no knowledge or time to develop a new Rom for the G Pro and there's no telling when we'll get one that could fix my issues.
Is anyone else having these problems, or does anyone have any suggestions?
Thanks!
For some reason my phone decided to play music using "Phone Audio". I disabled phone audio for the device in bluetooth setting, then it connected as an AV signal, and quality improved drastically.

Thanks for the suggestion. Just tried it, unfortunately did not seem to make any noticeable difference for me. To clarify, the sound quality is fine for the most part, it's just at certain frequencies I hear crackling.
By the way, earlier I also edited the audio.conf file under /system/etc/bluetooth and changed the values of "SBCSources=1" and "MPEG12Sources=0" to 0 and 1 respectively, which I read should force better quality out of bluetooth. Additionally I changed the value "Master=false" to true, which I also read could improve quality. It might be my mind playing tricks on me but it does seem to sound better, however I still hear the crackling at times, so I'm definitely not where I want to be.
Highly disappointing. Any other suggestions?
Which music player are you using on your phone? And have you tried any of the equalizer apps from the market?
Sent from my LG-E980 using xda premium
I've tried both the Music app that LG includes, and Google's Play Music app, which I prefer. No difference. Have not tried any equalizers, but not quite sure what that would do aside from eliminating the frequencies that have issues through bluetooth but work fine through an aux input? I don't consider butchering the music as an acceptable solution, unfortunately.
try this, it might help

Just out of curiosity - how did you find out editing the audio.conf file? I'm looking for a way to boost the output volume for my bluetooth, did a quick search and saw your post and it made me curious...
Will this change boost the output volume at all or is there a separate line or file to be edited?
Thanks for your help.

audio skipping...anyone else have this problem?

I've searched the forums and found quite a bit of people saying they have experienced this, but I'm not sure if they were using notes or not.
For some reason, it doesnt matter what app I'm using, pandora, xm, or the stock players. They all studder just slightly, sometimes more so when the screen is off.
It's not a bluetooth specific thing, it happens over bluetooth as well as the speaker of the note3.
Is there a solution for this? It really drives me crazy and how can I host a party next weekend with this doing that
My girlfriend does not experience this on her nexus 5, is my problem specific to jellybean?
Thanks for your advice!

yep same problem.
i had it on nexus 4 - 4.3. but um, didn't start on my note 3 until after a few days of use. I'm not sure rebooting helps for long. i tried poweramp and jetaudio and stock player. Skips everywhere.
I tried setting decoder priority and buffer size to higher on Poweramp. Not sure if it'll help but we'll see.
I'm on N2 right now that has exact same problem, but BT only related. The micro pauses also differ between the receivers Sony Ericsson MW600 is so far the worst offender, the pauses last 1/2 second, on other receivers it's barely noticeable.
At least on N2 it's not related to the JB version, it was happening on 4.1.2 and 4.3. Changing kernel also doesn't affect the issue.
I suspect the cause is BT doesn't get enough priority and if lot's of apps running on the background it starts skipping. Usually I just reboot the phone then it works fine for a few hours, sometimes I use fast reboot app, that kills background processes it helps somewhat too.

Using PowerAmp I went to Huge buffer and Highest priority and it seems to have fixed the stuttering for me. I'm on rooted stock.
>Using PowerAmp I went to Huge buffer and Highest priority and it seems to have fixed the stuttering for me. I'm on rooted stock.
yup. same. now wish they'd add the same features to jetaudio+ and other players D:
I get this problem often. Odd.
I'm not sure if this is a solution but I noticed the problem went away when I was using different roms/kernel combinations.
Currently I've been using the compulsion kernel with some international roms and the problem hasn't come back!
Is it the kernel or rom I can't be sure. But either way it's fixed.
If someone experiencing problems with their rom wants to try the compulsion kernel and see if the problem still exists maybe it can help a lot of people.

[Q] Crackling audio with KitKat

I recently updated to the deodexed stock kitkat rom with kt747 kernel. Everything is running fine except audio files in every program but poweramp have major crackling/static issues. The audio files play fine on my computer, it happens both over headphones and through phone's speaker. I use poweramp for all of my music but am really missing being able to use pocketcasts. Audio in youtube app also works fine. I have tried a factory reset and am at a loss for what else I can try to fix the problem. If anyone has any advice or tips or is experiencing a similar problem I would be very grateful to hear from you.
I think that the DSP doesn't process it right with a KK kernel although I do not have issues on stock kk ......have you tried a different audio processor like DSP manager or viper4android etc....?
Tried both of those and it didn't seem to help. Oddly enough I had one podcast today that I was able to play through pocketcasts without audio issues, but all the rest of my podcasts were ****ed up.
Well try a different kernel.....I read reports that some kernels don't provide enough power to the DAC and so it can cause crackling
