I am having a problem streaming A2DP music. On some of my songs there is static when streaming to my sound system. When I used another phone (myTouch 3g, and iPhone) the sound quality is perfect without static.
Has anybody noticed static on some songs (mostly songs with a lot of guitar and voice going on at the same time)?
Is there anything I can do to edit the blue tooth and stop the static? Maybe a tweek/hack? Its not the worst static, but I am picky when it comes to music quality.
Thanks!
Install SRS WOW HD 121 and fiddle around with the settings. You have to search for the cab yourself. It will improve overal sound quality and maybe let you reduce static.
ive had that problem as well sometimes what i would do is turn the headset off and then back on 1 or 2 times and then its gone i think its just a bug
I installed the srs wow hd 121 and couldnt find the file to fun it. also, i would get an error when trying to enable bluetooth. because of this I uninstalled the program.
I reset my phone many times and it still didnt stop. the static seems to be getting worse. I cant even find a a2dp key in the registory.
do you have a cab by any chance for it?
Thanks
It could just be my phone, but has anyone noticed their music sounding like it have really really small breaks in the sound, almost like the music is crackling? I've even found this when listening to my Sirius Satellite Radio app.
Though I may have found a fix, at least for the music. Originally my music was 320bit and i had just copied a few songs to my GN. When I started to listen to the music i would get crackling like sound or where the music would have almost a stuttering factor. Well i was getting annoyed enough with the crackling I almost went back to my MP3 player. Though I decided to try it one last time but i wanted my entire playlist. Now my playlist was about 200 songs and across many directories so I wasn't going to try search the whole thing for individual songs. Using winamp I copied them all into one directory, unfortunately when Winamp does this it converts them all back down to wav files so I had to reconvert them.
My software for converting back to MP3 is older and only able to convert up to 256bit. I was thinking it was going to be just as annoying, but low and behold my music plays without a glitch, or crackle or break or what ever.
It's almost like the phone can't handle the higher quality of music. Now again this could just be me so I thought I would ask. Unfortunately my Sirius Satellite Radio app still crackles.
Anyone else find this?
also if u have used an app like volume+ to increase your speaker volume, or modify your volume that could be the issue
Good thought, though i never actually got around to installing the app so we can eliminate that as a cause.
Oh no, lossy to lossy transcoding! Those poor files.
I haven't had any issues playing 320kbps MP3 CBR or MP3 V0. If anything they sound better than on my old iPhone 3GS, especially with DSPManager.
Do they play without any distortion on your PC? Are you using the same headphones?
Perhaps playing around with the equaliser settings in DSPManager would improve the output.
Have had the same problem but only with one album so far, it is 320bit but I also have other albums at 320bits that play ok. Strangely the problem doesn't occur if the screen is on!
Give me to this weekend and let me hoot the phone up to my input on my PC maybe i can let you all hear what I hear.

I would agree too if I had actually installed volume+
I don't think it's to do with the bit rate as such but the encoder, or at least the encoding settings, that you used. Almost all my mp3 are in 320 kbps, CBR and VBR, and they all play fine.

the phone seems to clip a lot when the volume is at the top two levels. sounds bad. setting it to 3rd highest level or less makes it sound normal and smooth
Not sure if they fixed this with 4.0.3 yet, but it's a known issue that any SAMPLE RATE (not bit rate) other than 44.1KHz can cause stuttering when the phone is in screen-off low power mode. Some EQs that cause the cpu to work have been known to fix it. Also changing the buffer size in PowerAmp has also I think. There are a few threads about it. I have recreated it with another persons 48KHz sample rate mp3. All mine are 44.1KHz and I've never had a problem with any of them, they all sound fantastic.

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

Does this help with volume output?

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.
Hi,
most of the time, I'm using my phone for listening to music, and since I own Galaxy S4 Mini (GT-I9195), I'm thinking about throwing my 320€ worth smartphone in trash. Mostly I'm listening to rock music where basses are very important. When I was using stock firmware, everytime I increased the bass level, the music volume diminished. It came so far, that when I was traveling from work to home by bus, I could hear what people around me were talking to, even though my volume level was on 100%. Then I somehow increased the volume of my phone (I found a thread how to do that here on xda), but then the next problem became annoying. Almost every time I skipped the song, the equalizer settings went back to default. So every time i had to press menu button --> settings --> equalizer, and then basses went back to normal. Sometimes equalizer doesn't work at all, until I reboot my phone.
So I tried with Cyanogenmod today, and I'm even more disappointed with music quality. Every time I try to turn on bass boost, the music starts to crackle, even though bass level is only on slight. I'm using 120€ worth Sony headphones, which work great on any other device, so the problem definitely isn't in headphones.
Does anyone deal with the same problem? I just don't know what to do anymore ...
Thanks in advance & sorry for bad English.

Hello there.
First off, if you are going to throw S4 mini into trash, you can instead send it to me and I'll pay for the delivery, as I simply love the phone.
Secondly, I think the problem is you and not the phone. I have S4 mini and I love listening to music. As anyone who loves music (proffesionaly or unproffesionaly) knows, basses ARE NOT THE ONLY (and most) important thing, even in rock music. And as far as basses goes S4 mini does a very good job, as it does in other spectrums of music playback. The volume decreases a bit if you set it to bass, because the equalizer decreases the treble value, thus you get the perception of decreased laudnes. Although I would recommend you get your hearing checked, as the laudness of S4 mini seems to be laud enough for others.
If you really like to listen to high quality music and are a true audiophile, than you wouln't be listening to the music on S4 mini on the first place, but would go for a high quality professional grade mp3 (or FLAC) player with an external amplifier.
Therefore I conclude that you are just a bass freak who wants to complain, but please feel free to prove me wrong.
My opinion and advice may not matter since I don't own a s4 mini (would love to have it)
But did you tried sound alive from Samsung?
Just increase the bass and some clarity then reverb and room size (if you like) then the bass is on a good level, wanting more bass than that would only get in the way of the guitars part!!
Or try viper4android if you're on a desperate situation...
Can I ask something here?? Is the smart volume feature any good??
@Shiningb
Firstly, thanks for your answer. I realized that everything works perfectly with stock Samsung Music app (which doesn't use build-in equalizer, but uses it's own one). The quality of sound is really great.
Only problem is that I prefer Google Play Music which is much clearer, easyer to navigate and overall has nicer interface. But there I deal with equalizer problem; the sound is great at the moment, the equalizer is set the way I want, basses are great, but then suddenly (without particual reason) equalizer just goes flat and the volume increases for about 30% rapidly which is a great way to go deaf. Then I have to restart equalizer app, and it starts working normally again for about next 10 minutes. Until I won't find the solution, I have to use stock music app, ok, i can get along with this
I googled about the issue and I found that it is quite common with S4 users. I heard about ViPER4Android today, and I'm going to try it right now, thaniks for your advice !
And sorry, I don't know if smart volume feature works good, I use mp3gain app on my PC which equalizes volumes of all tracks on the same level and works perfectly.

This happens with equalizer because the system kills it from the ram
So a great solution is to use viper...
But you need root and put the apk of viper into system/app set permissions to rw-r-r
Like this it won't be killed, because it will make part of the system app
By the way what kind of music do you hear??
I'm a sound freak with viper, I tunr things like crazy until I reach the perfect sound (for a time!)
I really wanted to know how the smart volume works since the I9070 won't have a official 4.2.2 update :'(
Thanks for fast answer.
I installed ViPER4Android, but everything I try to change, doesn't have any effect on sound. I don't know what is wrong ...
Could you help me with Viper? I know how to put a file in system/app and set permissions.
My phone is rooted I'm using CWM and stock android from Samsung.
My favorite artists are 30 Seconds to Mars, Billy Idol, Bring me the Horizon, Foo Fighters, HIM, Kings of Leon, Oasis, RHCP, etc.
Sry, probably really won't. I owned I9000 before I9195 and it was the best phone i ever had, even better with Cyanogenmod
Since the first time i connected my earphones, sound gets really low and at some times it goes full real sound but when i change song goes down again (its not the song since it also happens when i go back to the same song)
Already did a factory reset, enabled sound enhancer, used the equalizer.
It's like its stuck at the middle of the sound bar and wont go higher from there.
Apps i use: yt music, spotify, twitch, youtube, tik tok, instagram
While I haven't personally experienced any bad sound quality maybe these links will help to improve the quality.
