[Q] Cyanogen mod Bt handsfree and bt audio features don’t work if Music player paused

What caused issue: newest cyanogen mod update
After updating from CM 7.1.0-RC1 to CM 7.1.0 my Bluetooth stereo in my 2011 toyota camry (when connected) only plays the mp3 (Music) player on my EVO. If the mp3 player is paused, no audio will come through from anything on my phone. All other applications, be it handsfree phone features, streaming apps, Pandora, youtube, google maps don’t come through the stereo. If the audio player is being played, other apps’ audio can come through.
Now I know the Cyanogen team messed with the Bluetooth stereo because my car stereo now displays the mp3 track names and it never did before the update. I would gladly forgo that feature to return Bluetooth audio normalcy to the rest of the phone. Even stranger, on my dad’s 2010 Lexus es, which has an older version of Bluetooth stereo, EVERYTHING works just fine! This makes me think that this is an issue related to newer bt stereo models.
It could be a while before the Prime comes to Sprint, also could be a while until CM gets ICS working on Evo supersonic.
Please help.

I am experiencing the same problems exactly as you described with my 2010 Toyota Camry. I have only been able to get the "stock" ROM with the "stock" kernel to give me full functionality. Even with the stock rom, if I upgrade just the kernel, I get the same problem. Did you ever find a solution? I have been researching on the various forums and the internet and have not found a solution yet.

[Q] Music over Bluetooth to car stereo?

Is it possible to play my HTC One X music over bluetooth to my car stereo?
I have seen evidence in other HTC forums that it might be but I cant seem to make it work, when I pair my phone with my stereo i can make calls through it but when I play music it comes out of the phones speaker instead - any ideas?
If not i'l just use the audio jack cable aux input like i did with my old HD2...

I find it rather hit and miss with me. It does work, but sometimes I have to reboot the phone before it will connect to media audio. Other times it just connects to phone audio, which is very annoying!
Wonder if its a bug?

It's a Bluetooth receiver that plugs into the 3.5mm aux. Simply connect to the One X to the BT Receiver and play your music
EDIT: One thing to bare in mind is that is does require power. You would need to purchase a 12v adapter to plug into the cigarette lighter.

The phone will output to your stereo via bluetooth, set mine up yesterday and it was working fine, not used it enough to see any problems but it definitely works assuming your stereo is compatible.
there is an option in the ics music player to pick what output you want it to play to, menu/select player, and your bt stereo should be listed if its paired correctly.
Should display artist track info on your stereos display and allow you to skip tracks etc, didn't actually try that yesterday but my HD2 could do it so will be a bit miffed if the One X can't.

That will only work it the stereo supports A2DP

My DHD working with my Kenwood headunit but I cant get this phone to play via bluetooth anymore, when i select the stereo in the music player nothing happens!

Sorry, but HD2 has a AVRCP 1.3 but all of HTC Android series has AVRCP 1.0 version... Soo, not artist or track info transmit to device.. It's android related thing, not HTC's fault...
But, Samsung Android phones has AVRCP 1.3 (SGS II, Note..)... It seems, Samsung make different bluetooth stack instead of stock android one...

connected my one x to my car yesterday (normal VW golf audio system) via bluetooth.
calls AND sound both work fine, without any problemes. Like it did with my DHD
greetings

jabra bt3030 is another alternative, it connects to phone via bluetooth and then you can plugin a 3.5mm headphone cable to your head unit - only thing is , a2dp sucks compared to simply plugging in the phone, its quieter and the quality isn't as good.

Exactly my thought. The only reason to have BT in such a scenario is to let people in the back seats control the music. In all other cases, if you have to use an extension cord anyway, why not plug it directly in the phone? The only BT "dongle" that makes sense (in that eliminates the need for a cord) is the HTC one that plugs directly in the aux jack socket of the car stereo (IMHO, and excluding sound quality from the equation).

Does anyone know of a way to actually STOP it automatically playing music over bluetooth?
I have a Ford Mondeo and had the same irritant with HTC Desire in that once connected, it will automatically start playing music over bluetooth. All well and good apart from when I want to put a film on for the kids in the back and have the audio over the stereo.
All I want is a way of telling the in built music player to not start!

Well that sucks, im sure some roms will have it given time though

Bluetooth Audio One Sided

When I connect to media audio via bluetooth in my car, I can only get audio out of the left side speakers. This is repeatable on different apps that play music. When I play a radio station in my car I get sound out of both sides.
What can I check to help diagnose this problem and hopefully fix it?
Thanks.

Does anybody else have this problem?

Does your car audio system support A2DP stereo Bluetooth profile ? Probably it does, otherwise I don’t think you can stream audio with just the Hands-free (HFP) profile (which is a low quality link meant only for calls). Mine works fine in stereo with my car’s audio system. Try deleting all the BT settings from your car and initialize everything from the beginning.

Iam verry sure that your audio car not support A2DP because in my car i can use for stereo...try to see the specification for your car audio bluetooth..
Sent from my HTC One X using xda app-developers app

It works fine when I use my Galaxy Nexus. This makes me believe it supports A2DP. This problem is unique to the One X for me. Did I get a bad phone?
Also, when I crank the balance over to the side that doesn't work I can hear it a little bit, but it's crackly and distorted.
EDIT: Problem solved. Re-seated the wiring in the sound system and everything is fine now.

Are you listening to streaming music while driving? Bluetooth or not...

Hello Everyone,
We here at iBOLT would love to find out what percentage of Samsung Galaxy S4 users are listening to streaming music from their handset while in the car. As your S4 has access to great music Apps like Pandora, Spotify, TuneIn, Slacker etc. it would be great to find out what percentage are driving a car equipped with car-stereo that features Bluetooth Audio Streaming (so called "A2DP" profile). If not, what kind of speaker do you have set up?

Don't have a car, but when I ride my motorbike I use the S4A to listen to music through my bluetooth headset in my helmet.
And if I were to buy a car, the ability to pair it with my phone (also for a2dp) is definitely important.

I stream both Internet content and content stored on my device. The content isn't what's important. What's important is the ability to stream the content through bluetooth to the radio.

my car has a Galaxy Tab 2 7" in my dash board so most of my music is played right off the 16GB MicroSD Card in the tablet, but when I do want to stream from my Subsonic server at home I do it through my phone. I do have a BT Headset (Samsung HS3000) which supports A2DP wired into my car speakers, but from my phone the volume is super low for some reason, so I usually just plug my phone into the 3.5mm headset plug I have also hooked up in my car.

I just use simple wired headphones because my bluetooth set fell off my head and shattered to tiny bits on the floor it's funny cause it still works but there's no way to get it back together again. I only use play music at the moment. I'd rather not stream because it bites into my data plan with sharp pointy teeth. That crap leaves marks!

Well I use my Plantronics Bluetooth headsets while I am in the car or on my bike...the music quality is superb and it just makes me to enjoy the track with driving though and its quite easy to answer the calls even so I just love my headsets they are pretty awesome one to use.....

I like listen to streaming music while driving, cause it can make me sober when drive.:laugh:

mainly using deezer for streaming with 3,5mm jack !

I do.

Is your car stereo a kenwood? I used to be an installer and a lot of kenwood bluetooth models have a default setting to play bluetooth audio through only one speaker. This had me stumped for a while, but what you need to do to change it is to put it in the "standby" source, and then access "detailed settings" and look for a setting I believe is labeled bluetooth HF audio or something, enter that setting and you can change it from "front/front only" to "all". It took a while for me to finally find it because you need to be on the standby source and access the settings. You'd think to be able to change it while in the bluetooth source. Hope that solves your issue.

anyone play music in their car with this and have it NOT suck?

Wondering if there's a secret. It's like everything below 200mhz has been removed, both through headphone jack and bluetooth.

Sound quality for me both on Bluetooth and headphones is great

Sounds good to me

Same here. Good quality in car whether i use my bt adapter or through audio jack.

Using Vanilla Player to play local mp3s sounds good on my headphones. Maybe a little "small" on my BT speaker, but its a small cheap speaker. Haven't noticed poor quality in my car.

I do use bluetooth pretty much exclusively in the car. I have a pair of headphones that sound really good with the phone. Dont use anything else to play music but I do sometimes have problems with the headphone jack when I move the cable around.

The sound quality when connected via cable to my car stereo or headphones seems to be fairly decent, though a bit noisier than the audio I get from my iPhone. I still have the problem of losing audio on calls after disconnecting from the audio jack (I can't hear callers on incoming calls and sometimes callers cannot hear me when I call them) and then having audio not re-routed back to the audio jack the next time I connect. Because this has happened on more than one Fire phone, I just use a cheap Bluetooth USB adapter connected to my stereo which does degrade the audio quality somewhat however.

Do you guys use any sound processing apps at all? I seriously have no bass coming out of my phone. I turn the bass up almost all the way on my car stereo, and in an EQ app for the phone (tried without the app too), and it's still not quite what a normal mp3 playing directly on my car receiver sounds like.
I'm on fire OS, are any of you on cm11?
Also this uses dolby or something doesn't it? I worry that something I've disabled has messed it up, but don't know what it would be.

No sound processing apps for me. I'm usually on Fire OS 4.6.3 rooted with no Google Play services. Now I'm on 4.6.5 unrooted (trying to resolve a GPS issue) and it sounds the same over BT.

Works fine for me too. Hardwired through AUX or with Bluetooth. Headphones/earbuds sound good too. I mainly use Amazon Music player, Google Music, and Pandora.

I've had no problems with BT connection from my Fire OS Fire Phone to my Sony receiver. Bass response is good whether or not I am running "Equalizer FX." I use Equalizer FX because the bass on the car stereo (and my headphones) rolls off below 60Hz.
I have learned from other phones that running the volume at max level can cause clipping and sound degredation.
