Looking at the source, there are at least 4 codecs: SBC (mandatory), MP3 (MPEG12), AAC (MPEG24) and Sony's ATRAC. ./android/external/bluetooth/bluez/audio/a2dp.h: #define A2DP_CODEC_SBC 0x00 #define A2DP_CODEC_MPEG12 0x01 #define A2DP_CODEC_MPEG24 0x02 #define A2DP_CODEC_ATRAC 0x03 The underlying software is linux' "bluez" ...

I was searching for a fix to this exact problem and came across your post. I just found this. I remembered your thread and thought i would come back to share this with you. The guide says to: Open Bluetooth Launch and scroll down to “Voice Search”. Tap on it to expand it out, then select: “com.google.android.voicesearch.RecognitionActivity” but i found ...

Go into settings -> apps and click all. Then find voice dialer and disable it. That should disable the voice dialer app and Google Now should come up when you press the call button. If that doesn't work you can always reenable voice dialer.

The Advanced Audio Distribution Profile (A2DP) is a source/sink configuration. In an normal scenario, you have a source (for example, and Android phone) and a sink (Bluetooth headset/speakers). But in your case, the Android phone would have to act as a sink to the dumbphone source. This is not currently supported, even though the phone supports the A2DP ...

You can accomplish this by disconnecting the stereo audio (A2DP) profile from your headset. This still keeps your headset paired with the hands-free profile. You can do this by opening Bluetooth settings, long-pressing your attached device and unchecking Stereo audio.

On my Cyanogen 10.1 phone (AOSP 4.2.2), it is possible to enable a capture of bluetooth traffic. You can then load this capture into Wireshark and look at the negotiation phase to determine which codecs the paired audio output device supports. Not sure what OSes support this: when I first ran across this method it claimed support only from 4.4 onward, but ...

From the Samsung tech support, they say that: when the AUX cable is plugged in, Blue-tooth audio is dead. However, from the ICS Options during a call: During a call, you can also use buttons near the bottom of the screen to: Switch to the dialer, for example to enter a code. Controls the audio output as follows: If a Bluetooth ...

Try an app named SoundAbout. It can let you configure this to work.

I've released an app called SoundAbout on the Google Play store that may help.

The feature uses Bluetooth AVRCP, the Audio Video Remote Control Profile. It's used for controlling the app from the receiver (e.g. play/pause buttons on a BT headset). AVRCP level 1.3 is possible since ICS and improved in Jelly Bean; it allows all of 1.0 (play, pause, next,...) plus metadata information on the track itself (artist, track name, etc.). It ...

I can think of 2 ways you could do this. Bluetooth audio adapter, like the Antec BXR100. These are generally used for headphones, but should be able to simply connect into your amp. -Pros : Simple, cheap -Cons : Bluetooth, limited range, A2DP appears to have issues on Android 4.2, possibly non-optimal audio quality DLNA renderer (mini computer ...

I'm not sure if this is true for other phones listed above, but for The Galaxy Note II, I had to make sure S-Voice was disabled (it says Voice Dialer on the first post). Also, if you have downloaded bluetooth launcher you probably already tried: "Google Search" and then selected "com.google.android.googlequicksearchbox.VoiceSearchActivity" and was still ...

The reason for the Bluetooth icon being disabled is that you haven't paired the phone with a device that supports the Headset profile. Bluetooth uses profiles to categorize which services a device supports, and Macs don't support acting as a headset, only connecting to a headset (see list of supported profiles). To use this functionality, you'd need ...

There's a Bluetooth connect & Play app that can intercept the incoming "play" command. While it was originally designed to let you start a specific music app playing when a specific Bluetooth device connects, you can instead select "STOP music from playing" to keep any app from starting when the car connects.

This is pretty hard to do with software, since there are delays in the audio stream. The transmission from you phone's BT to the headset can take up to 200ms, and the same for the reverse. Therefore before sending the audio from the mic to the recipient, up to 400ms of audio would have to be sampled and cancelled, assuming that the BT connection is stable. ...

Unfortunately A2DP supports only stereo audio, it doesn't support two-way audio, i.e. your mic woud be useless if the calls were routed over A2DP. You'll have to enable HSP for call functionality.

If you want a specific app to react to bluetooth commands, you have to set it to high priority. I know PowerAmp has such a setting. Check the spotify settings for a high priority option.

Its not only your device's issue, but also in most of the devices. Android 4.2 has this issue. And Google officially confirmed it . Look above link "We have fixed the a2dp streaming stutter problem on N7. The next release should have the fix.Sorry about the problem." Android 4.2.2 fixed Bluetooth audio problems on Nexus phones and tablets. You just try ...

Solved: The android system is likely connected to the headset for phone calls, and some other device for A2DP (media). Some other device is still using the audio connection, even though the sound comes from android's speaker! What this means is that if you have any other A2DP devices that you've paired your android with (laptop/stereo/etc) then you will ...

AVRCP is not supported in most players. Mostly in the stock players and CM,s Apollo, unfortunately the stock players are crap and unusable in terms of sound quality. Double Twist player has partial support, song title shows but not album title.

SOUNDABOUT from Google Play Store SEEMS TO HAVE FIXED THE PROBLEM FOR A LOT OF PEOPLE - SEE USER COMMENT BELOW Samsung Galaxy S3 Developer has worked continuously to make this app work better. It solved my major issue of allowing my SGSIII to play music through the headset jack to my vehicle and answer phone calls on my OEM bluetooth. Before this app to get ...

I don't think that base android supports avrcp beyond version 1.0. A lot of the community created ROMs have added support for the other levels into their custom systems. However the stock version doesn't have it.

Try Hint2Search. I helped beta test and it works wonderfully! Simply connect your Bluetooth headset, press the button on the headset, select this app as the default to open on your phone and select always. Now just press your Bluetooth headset button and boom! Google now opens! Should work with cars as well if given the choice to select "default action" on ...

See my answer to a similar question - the problem is that within the Bluetooth AD2P profile (for stereo quality audio) Android phones aren't designed to be a "sink" (a receiver of media) only a source. You're right in that this is a limitation of the Bluetooth stack on your phone, but so far the info I've found says that trying to alter the stack comes with ...
