Hi,
i have Galaxy S with I9000XWJM5 and have some strange problem when listening to music in my car. I connect phone with AUX cable to my car radio.
The problem is that playback have glitches every few seconds, it's 4-6 glitches per minute of playback. I don't know how to exactly explain that glitch. It looks like you quickly disconnect/connect jack to phone. I've had iPhone, Samsung Wave and several other mp3 players connected that way in my car and none of them had these kind of problems. I've also checked jack and cable and everything is fine. Connection to phone is also fine during testing. Do you think it's because software? Or maybe it's bad checking for AUX signal in the phone?
I'd say most likely software, but I'd be guessing.. There isn't really any way of knowing.. Is this with FLAC?
I'll try change something in my car audio. I think it might be caused by changes of inpedancy.
I don't get glitches in my car AUX unless the files themselves glitch and stutter (which they do with FLAC files). I would check to see if you have any EQ settings in your car stereo on, that is the culprit sometimes.
How is your playback with headphones/earphones? If you don't have same problems with them then it's likely something with the mini cable or the car stereo. If not, then likely something with the phone hardware/software.
Playback with headphones is 100% good (sometimes excluding FLAC playback as you said). I'll try changing EQ in car and if this don't help i'll try changing inpedance and write here what happened.
have you considered using bluetooth in car to stream audio from the phone instead of AUX cable?

I was thinking about it but my car radio don't have bluetooth and I won't change it because it's pretty high end Blaupunkt and I love how it sounds.
Second thing is that a2dp has lower quality that regular aux.

I would also make sure it's not the data/phone connection somehow getting in the way of music playback. Try it on the airplane mode and see if you are getting the same glitches.

i think i know what you mean.
you are refering to those annoying sounds when a call is about to coming, or when a data transfer is in progress, or whenever your phone switches from one tower to another tower
you get the ddddddd...d.d.d.d.dd..ddd.d.d.d.d.d.d.dddd... sound on the speakers, if your phone is connected to the stereo via 3.5
that's one of the reason why i switched to BT in the car.
I've checked line out with amplifier in my house and it's working 100% fine. So i have to check AUX in my car.

Hello,i want to change my wired earphones to wireless ones, so ive been searching for a bluetooth headphone that would be good not only to listen music but also good at watching movies and i couldnt find any that dosnt have few secs off delay . So anyone knows any bluetooth headphones without the delay?
I've got some dell BH200 bluetooth headphones. They work great; no delay at all.
LOL delay! a Few seconds! Who the hell would buy them?
I been using the much whined about S9(9) motorolla stereo bluetooth headset for almost a year. Got a call in to radio shack now to replace them, (volume is all that dont work- dont leave them in your glove box in 140 degree heat lolz!!)
Ive never experienced any sort of (noticeable) delay with my bluetooth, i use them for everything. Movies of all different formats even.
Im not sure if your implying that after reading the specs you think theres seconds worth the delay, or youve personally experienced it. But This kid never has.
We're talking milli-seconds not full seconds.
Do it the right way like i did, and turn in your 120 dollar receipt at work.

A2DP is designed to have no delay, so no A2DP set should have one... I have one set of BT headphones, an adapter plugged on my hifi set, and a 3rd one on portable speakers, and none have a delay. I'm also using A2DP between my laptop and desktop PC (so that the sound of the laptop goes out on the 5.1 set connected to the desktop) and there's no delay either.
So if you did experience delay, you must have stumbled upon THE rare crappy model.
Did you check the video for delay?

Some video if not properly encoded the audio will be out of sync and will get worse as it progresses into the video. You should compare the same video with the wired and wireless to verify the delay.

unfortunately when i connect bluetooth to my car radio the music skips about every 15 sec. very annoying. Anyone else having the problem.
I have an iphone 3gs that doesnt skip and works great. I love the Evo but bugs are continually showing up.
Its your internet. Try updating your prl.
i did update the prl before i tried it.
still does it.
I have a bluetooth reciever for my AVR and I noticed some skipping as well. Not as frequent as you are saying but if I moved more than 10' away it would be rather bad. The Bluetooth range seems to be poor. In a car I can't imagine you having a problem. I have heard of some issues with factory bluetooth.
I had same problem till I decided to turn off my wifi.. and it started working fine.. it just doesn't have to do with Pandora, its will any Music that you stream over Bluetooth..
Just turn off your wifi and it will work fine.
Thanks
Or just place your phone somewhere else in your car. Bluetooth has very lousy range (isn't it like 10 feet in perfect conditions?), and as such moving it a foot or two somewhere else could make a world of difference.
Its definitely not the internet. I could be at home in wifi with phenominal internet it even laying it off of my SD card. If im in a vehicle or on a bus, its pretty solid and works really well. I walk out the bus and walk around either to m next bus or to work and it fails to play for more than 4 seconds without skipping. And its not like a short, nuisance of a skip. It often stays skipped for up to 3 seconds at a time. Completely unusable. Happens however i connect my phone to any a2dp device. Tried tweaking the /etc/Bluetooth/audio.conference file as suggested in a couple nexus one/s sites, but unfortunately seems to be specific to those phones. This is making me hate this phone. Every other phone I've had in the past two years does this just fine. Whyis it having such a hard time with such a simple task that others have done perfectly? Even other Roms work better but i like also better than sense anyday. Maybe its a kernel issue?. I really want this fixed. But it seems like no one is even trying to work towards a solution. Not on the surface anyway.
Did you try turning off your wifi and any other unneeded services? The only time I have had skipping over bluetooth is when I have my wifi on as well, other than that it streams smoothly through my car stero and computer over bluetooth.

This.
If that doesn't help, then if possible, you should use an aux in cable to prove it's only a bluetooth issue. If it still skips, I'd try a new rom and/or kernel. A2DP performance seems much improved in CM7 compared to Sense roms.. or at least it seems better to me.
I've had the same skipping problem with my bluetooth earphones and evo. The only slight solution that I've had was holding the phone in direct line of site with the bluetooth earphones. When I do that, it doesn't skip as much.
Streaming bluetooth audio to car stereo
Thanks Anku13, your fix works. Just installed a Clarion CZ501 bluetooth receiver in my car, experienced skipping audio every 15 - 30 seconds once my Leo connected/streaming. Killing WiFi was the trick. Love not having an AUX cable lying around in the cabin.
I'm able to connect my Atrix to my JVC double din in car stereo system via bluetooth and it connects and pairs just fine. The problem I have is that the music "skips" or loses sound every few 20 to 30 seconds. It plays the whole music file but seems to drop out here and there. My old tilt 2 played on this same jvc beautifully using bluetooth. But the Atrix cant keep up? It happens no matter if I play music files through the stock android music player, or Power Amp player. What gives?
I also have a JVC Kw-Avx810 with bluetooth adapter installed. I have the same problem, for calls it works perfectly but for music its a bitt frustrating to hear music skipping each 30 seconds. Sometimes I am able to hear the music without skipping and that happens when I first play the music on the phone and while the music is playing on the phone I turn on bluetooth on the phone and the after 10 seconds it begins to stream the music to the Jvc Unit without any problem. I do that every time that I wanna hear music on my Jvc unit. Havent had any more issues so far.
I use it for my ford sync and at times it will do strange things that my nokia n95 never did but for the most part it works well...

I had a similar problem when I had my streak. It was because I was pairing Audio with one device and bt phone with another. If you are doing this it will cause that. I use my Sony stereo just fine, will disconnect occasionally, but quality is great.
I use my atrix with my prius, and so far so good.I haven't had disconnect issues yet.
I think it's something JVC could probably fix with a firmware update. The atrix streams just fine to both my Sony and Kenwood headunits.
I have the same problem.

The key terms: "Usable but not stable" , although it was not tested with Atrix, it is evidenced on both HTC and Motorola phones.
Great move JVC .. you've made your product useless to me and tarnished your reputation at the same time. Couldn't get your guys to write a new firmware ... Cant get me to buy another one of your products.
The same looks very like it will be true with Motorola's Andriod phones. Both JVC and Motorola will soon be wiped off my present or future ownership map. Woooo
Mine drops out/ goes silent / loses bt connection about once every 8-12 minutes when connected to my sony head unit (mex-bt5100). I turn off bt then back on, then restart my streaming radio.

I have a jvc double din unit too. I don't experience any issues with audio... however the phone is a bit garbled when connected.
Have you tried moving the bluetooth dongle to the front USB port?
Sent from my MB860 using XDA Premium App
i Have a single DIN (AVX33), the bluetooth is built-in so there is no dongle.
I read quite a bit about this problem .. it is related to the phone hands free profile sending signals to the headunit in a way that the headunit cannot handle without disturbing audio. It is exasberhated by low signal strength (both bluetooth signal and GSM signal), and also by the fact some andriods will give equal transmit priority to these hands-free signals that it does streaming audio. This is why turning wifi off helps a little (reduces interference). The signals that are interfering with streaming audio are the ones about battery life, and GSM signal strength. As signal strength chagnes, the phone sends out a new value despite the headunit not needing to do anything with it. This is what interupts the audio consistently but irregularly
End result .. it can be fixed by software adjustment on the andriod (do not send updates when streaming audio .. unlikely with Atrix unless Moto gets their thumbs out of their asses), by software adjustment on the receiver (unlikely as JVC is a **** company that does not care about my woes), or by mitigating the problem as I appear to be forced to do. I do this by turning off the "phone" porition of the bluetooth. Or by starting the music and THEN connecting to bluetooth. Unacceptable to me but I have no other options.
I f**king hate how complex our electronics have become and how consumers are powerless to fix these problems DESPITE the fact some of them have a higher level understanding of what the problem actually is. (therefoer I will not be purchasing anything from JVC or Motorola ever again. They prevent me from solving problems and refuse to fix them for me.)
Is there any way to fix the bluetooth audio quality other than switching to a CM-based ROM?
My old phone over bluetooth sounds fine. My S4 via a wired connection sounds fine. My S4 over bluetooth sounds like everything was sampled at 32 kHz. All other equipment is the same, so I'm relatively sure it's a bluetooth-specific issue. My girlfriend's S4 does the same thing.
So, any fixes? I'd really like to avoid switching to an aftermarket ROM right now.

Random guess: Could this issue be caused by the adaptive sound feature? I'm not a true audiophile, but I haven't noticed a problem through my receiver in the car or at home.
Try playing something with cymbals and a lot of treble. Turn the volume up a bit higher than normal while still maintaining a reasonable level. The cymbals sound like someone is smacking a plastic grocery bag with a stick instead of being crisp and clean like they should be. I can then disconnect the S4, connect my old phone, and play the same mp3 without any sound distortion. Or I can play the same mp3 from the S4 via aux and it sounds fine.
Try it on both bluetooth and aux. If you truly don't notice a difference, I guess it must just be my phone. If it does do it however, you definitely don't need to be an audiophile to hear it.
My old phone had the exact same problem until I moved to JB on a CM build. The problem there is well-documented as existing on the S3 (try looking up bitpool settings), but I kind of figured they would have fixed it by now. I'm coming from the world of HTC, so I was hoping there is a fix for Samsung.
Sorry to revive this thread, but I have an update.
My car has built-in bluetooth for phone only, so no a2dp. I have a third-party bluetooth adapter that I'm using for music.
I've found that when both of these are connected, the audio quality (especially on trebles and guitars with distortion) is absolutely terrible. That was the point of my original post. Since then, I've determined that this happens ONLY when I am paired with both my car and my third-party bluetooth. I can actually pair and unpair from my car in real time and hear the audio quality immediately get better/worse. The quality gets worse immediately when it pairs, even if the car bluetooth is not in use (but still connected).
I've verified this is the case with both my phone and my girlfriend's S4. Can anyone with such a setup verify this does or does not happen for them? I'm thinking this is a bug with the bluetooth stack, and it'd be nice if it could be fixed. If anyone can try pairing to two different devices and confirm my problem, I'll start a bug report with Samsung. Otherwise I'll try another bluetooth adapter for a2dp.
Hi Guys.
I've seen a number of posts on this subject so here's my story and my experience thus far.
I've been using an iPhone 7 since it came out. I've been very happy playing music in my car (Fiesta with SYNC2 system) all this time. My significant other has been using an S8 for some time, and her music always sounded 'crackly' (for lack of a better word) in the car. I thought this was just her Spotify or something.
2 Days ago I bought my own S8 and I had exactly the same issue.
Now from some research I've been able to deduce that this is down to the Bluetooth Codec the phone uses. I changed mine to aptX yesterday and the music quality was great. Didn't sound like a 200KB MP3 downloaded in the early 2000's anymore.
However...
Last night I had to reboot my phone for reasons, and the developer options reset completely, which I believe is normal behavior. But now I can't set my Bluetooth Codec anymore? I change it, the moment I close the menu, it reverts back to SBC. I tried this with Bluetooth off, Bluetooth on and not connected, Bluetooth on and connected, no joy. It keeps reverting. Same goes for all the other Bluetooth settings (i.e bitrate).
So gentleman I ask you humbly, wtf? Why does the settings not stick and is this normal behavior? Is there a way I can force it to use AAC or aptX once more? I really have come to enjoy this phone but playing music in my car is a very very big factor and since AUX and USB (can't seem to play Apple Music/Google Music via USB) isn't an option, I'm stuck with Bluetooth.
Thanks in advance,
Have you made sure dual audio is disabled???
If not, go to Bluetooth, turn it on, hit the tripple dots in the top right and tap on "Dual Audio"
Make sure it's off and now try changing to AptX or whatever codec works best for you.
Disable / re-enable Buetooth and see if it sticks. (Try rebooting too)
Also, Bluetooth codecs will automatically change if the device you're connecting to doesn't support your choice of codec.
Keep me posted

Hi Corey,
Thanks for the response. Unfortunately, the above didn't work Dual audio was disabled, I enabled it and disabled it again. I tried changing the codec and bit rate but the result is the same, the moment I close the menu or turn on Bluetooth, it reverts back to SBC and Best Effort bitrate. I should mention that when I turn on the Bluetooth, it doesn't connect to anything, the only paired device at this point is my car.
Interestingly enough, if I don't close the menu but just hit the middle button, the settings will stay as is and the audio is great. What I haven't tried yet is closing the menu after a 'good' connection is made to the car. It may be that the setting sticks but the menu says otherwise. But I can definitely confirm that if I close the menu and then connect, the audio is garbage.
As for the compatibility of the car's Bluetooth, well it's a Ford SYNC2 system which from what I can see is actually quite basic. I am starting to this the problem isn't as much the codec, but rather the bitrate at which the phone is playing/sending music across the Bluetooth.

I'm not gonna' lie, I'm not very impressed by the Bluetooth on the S8... or Bluetooth in general.
It's lousy most of the time, mine always distorts and especially around emergency vehicles... (Could be interference from their coms???)
If possible, just stick to good 'ol copper wire
I can't imagine wireless audio not ever being interfered with and will always stay wired.
Also, try a music app called Poweramp.
It has many settings involving latency etc. It has a trial for 2 weeks and is worth EVERY penny if you decide to buy IMHO.
Try the build version first, if that doesn't have settings that you need, try the alpha version.
It has lots of latency settings etc
I'm guessing higher latency = better results as it has more time to be pushed over BT before the sound is reproduced.
I'm probably wrong though.
Can't beat lots of settings tho aye.

Morning Corey,
Yeah so my situation at the moment is to have my old iPhone in the car at all times as a glorified bluetooth player. I've also gone out and bought an auxiliary cable for when the iPhone's battery dies on me (happens more often than one would think). And to have a charger for the iPhone, charger for the Samsung and aux cable for the Samsung all plugged in becomes really messy.
It must be something to do with the Bluetooth 5 feature. I don't know what version the iPhone is (cba to check) but it works like a dream.
Wish we had some form of backwards compatibility or a feature to force an older version with Samsung. Just sucks buying a phone which is really not cheap in ZA just to have the music sound like a 300kb MP3 played on Winamp with the treble bars turned up all the way.
I'll try out the app you suggested mate, thanks!

No worries and if you are referring to a USB cigarette lighter charger/USB charger then try the multi-cables.

sorry to drag up an old thread, i have the same problem ( sync2 too) and it is same issues. I have noticed that even though its bad its tolerable bad. then i add my samsung watch and becomes awful.
did you ever figure the issue out? i feel its the sync2 causing some kind of problem
