Bluetooth crackling w/my JVC Car Stereo [SOLVED]

My JVC worked fine with all my other phones.
But with the S3, I get lots of crackling sound whenever I use bluetooth from the SIII. I still get the music, there is just crackling that goes along with it.
I've tried stock ROM and several other ROM's & kernels, including AOKP and CM9. No change in the problem at all.
Gonna take the SIII to AT&T tomorrow to have them replace it, unless someone else has a better suggestion.

I've owned 3 different android phones and have experienced crackling in high frequencies with every single bluetooth device I've tested. Headphones, car audio docks, portable a2dp receivers... all complete sh1t. This is due to A2DP audio compression codec which producers these artifacts when audio stream becomes too complex for it to handle. No worries tho, as SGS3 now supports aptX A2DP codec so I'd suggest you start looking into bluetooth receivers that support aptX... or, just stick with good old analog audio over the 3.5mm audio cable. Many years of fighting A2DP and always come back to this rock solid solution.

Thanks, guys.
All my other phones were also Android.
If the replacement phone has the same problem then I'll try a newer car stereo and look for one with aptX support.

Also having issues
I have the same issue with my S3 and both my JVC car receiver and my Rocketfish headphones. Any other options besides upgrading receiving devices (my car receiver is very new)? Any possibility of changing the codec that is being used?

DIscussion on best APT-X headset/earphone for Galaxy S3

Hi Guys,
I know that the Galaxy S3 has APT-X enabled with Wolfson DAC. Can we discuss on some good headsets that will sound great with GS3??
What about external DAC like E17 USB DAC?? Will that make much difference in sound quality?

Thanks for your reply. Have you tried using sennheiser earphones? Many of them in XDA saying its wonderful.

Please share your thoughts and experience so that we can keep this thread live.
What about the external amplifiers like fiio e17?

thanks Venkatesh. Can you tell me where can i get this kernal?

Can anyone tell me whether my apt-X compatible Bluetooth headset will be able to make use of the apt-X functionality of the phone if I'm on an AOSP rom instead of a touchwiz-rom? Or is it kernel-specific?

[Q] Music volume is so low!!! Help?

So from November 2012 when I got my phone I have tried any thing came to my mind to solve this problem but nothing worked for me!!!
I'm very sensitive about music quality and I really can't stand this anymore!!! My volume is very low even when I crank it to the max!!! I mostly use my Dr Dre Studio headphones and sometimes my Beats Tours... I've tried several other headphones and didn't get any result
When I connect my Studio headphones to my laptop and I listen to the same track that I have on my phone it's super load like if I turn up the volume to the max I really go deaf!!! So I'm pretty sure it's not from my headphones... I know that the phone's amplifier is not as powerful as my laptop but still ... I think it is not normal, I also notice some other people have the same problem as me!!!
So these are the things I have tried already:
1. Using other mp3 player apps such as PlayerPro, PowerAMP, Winamp and .... none of them made any difference and the equalizer simply just mess up the quality of the track...
2. I have used all the mods like Beats Xlouder and such and they also just lowered the quality
3. All of my tracks are MP3 320kbps/flac audio format... still I tried to increase the audio using Audacity by amplifying the dB... It helped but not really noticeable.
Currently I don't have root access but if something can really help I'd be willing to root my device... like kernel or something! Please help

A ) There's something wrong with your ear.
or
B ) You have a defective unit. My headphones are waaaayyyy too loud even at half volume. If it's really that bad, ask for an exchange unit. If you're adventurous, root and custom rom it. Might see a change.

Google Nexus 4 Volume low you can probably see people having the same problem I you think I'm lying
If you think you can help please give me a solution to my problem...

Imma be as descriptive as possible with my fix.
ROOT YOUR PHONE!
1. Install Trinity kernel. (Its the only kernel I've gotten this to work with)
2. Flash Misledz audio mod, keep up with the latest ones as in my opinion she really knows what she's doing and the quality gets better and better.
3. Once the mod is installed Titanium Backup / Rom Toolbox remove the 4 system apps installed by Misledz audio mod.
-Awesome beats, -Noozy Player, -Noozxoide, -Dolby Digital App.
4. Reboot wipe cache / dalvik in recovery, reboot.
5. Go to the market and download the latest Noozxoide, set up to your musical preference.
Now you can omit some parts such as keeping 3 of the apps, but I find awesome beats not to work at all, the libs in the mod does though. That's why I remove the apps. I listen to a lot of bass heavy music (rap / old school hip-hop). This method is a night and day difference in loudness and audio quality.
I genuinely hope this helps everyone.:good:

dude Awesome beats is the worst ... plus I'm not rooted any more
but I heard there is a kernel that increases the volume

Not awesome beats. Misleadz audio mod. Trinity kernel makes your audio louder naturally. With the audio mod trust me you'd give me an e-hug in gratitude (no homo). I had the same problem. This method I posted works.

I give it try thanks a lot

What type of earphones or headphones do you use anyway? I'm using the V-Moda LP2's and they sound fantastic. They do need an amp to get the total feel but with Poweramp's equalizer, I have been pretty impressed.

GE 4.3 Bluetooth impressions

For anyone wondering the sound quality for Bluetooth is 1000 times better on 4.3.
I tested this on 3 different stereo headsets with beats enabled and disabled. It is extremely noticeable how much HTC/Google improved Bluetooth quality on the latest update.
This makes me so glad as Bluetooth quality with 4.2.2 was extremely lacking.

Is it better than the bluetooth A2DP support in the sense version of 4.2? because I use that dialy in my car and have been waiting for them to improve the quality or mods to this effect since I got the phone. I would install 4.3 and give up zoe's just for this.

OK just got done doing a side by side comparison with a stock sense HTC one, and quality is about the same.
I did notice that enabling beats on a stock HTC one has more bass than my GE but not much.
On a clarity and volume level they are nearly identical.

How about info from Spotify, does that work for you?

I just noticed something a bit ago. I was cleaning out my garage and listening to some music using my Motorola S9 HD stereo headset, and took some garbage out to the road and the music was not cutting out. I left my phone in the garage and the road is about 100 feet away from where I took the garbage. I have never had this kind of range before.

and the scary process begins changing the mid is such a pain, i'm sweating right now. I'm gonna go with the OTA update with this one. the dumps at the xda are being reported for problems.

Can anyone confirm if the sound quality is comparable to using A2DP with aptX on Sense 5? I currently use the HTC Car A100 Bluetooth dongle for streaming music, and when I was on the stock Google 4.2.2 ROM it sounded horrible.

Can we finally use Dualshock 3 controllers???

I use a Belkin bluetooth audio adapter and the sound is comparable (4.3 GE vs 4.1.2 sense). Don't know about 4.2.2 sense though. I don't have a custom stereo but it is a decent stock system. Is there a way to see if you are running adp?

I think I'll go ahead and test it myself and report my findings. I can connect the HTC car adapter to a pair of headphones, which should give me a good comparison environment. My new car also has built-in Bluetooth with support for A2DP, but since I've had the HTC car adapter for longer, I figured I'd be better off using the HTC adapter instead.
For what it's worth, Sense 5 using either 4.1.2 or 4.2.2 has the same sound quality since aptX is present on both, but I think CSR's "CD quality" claim about aptX might be bogus. I spend most of my time streaming Google Music at 320kbps (a.k.a. high quality) in the car, so if the Google ROM can stream ~320kbps over A2DP without the need for the proprietary aptX, I should be fine.

The Bluetooth on 4.3 is still using SBC instead of aptX, and there is a noticeable drop in audio quality when doing to 4.3.
However, it isn't really a deal-breaker for me. I'll probably end up just running an aux cable to my phone instead.

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
