Hi João,

Your pulseaudio A2DP patches for “handling bluetooth source”
and “add discover of bluetooth sources” are present in
PulseAudio 0.9.16-test7.

Can you please describe how can I use this latest pulseaudio together with bluez-4.50 in order to stream A2DP sound to the computer?

Thank you,
Paul

Hello João,

I saw that you posted on 16 August some pulse-audio patches on the PA mailing list for A2DP source.
Are they enough for streaming sound from an A2DP source to a linux pc ?

Hi João,
Gustavo Padovan told me about your work.

I am willing to test audio streaming between my computer and other BT devices.

Congratulations for your great work!

Best Regards,

Alan

indeed! I’m fairly excited for this. I’ve been trying to get this implemented on my PS3 so I can stream music from my iPhone over my stereo system (or play games, which would be doubly awesome). I’ve been playing with the old bluetooth-alsa and btsco packages trying to register a A2SNK with sdptool, but the iPhone just isn’t playing along. I use the a2recv binary from the btsco package, pair my iPhone, and start playing music.. but nothing. Good to hear there is some work going on for this again, those mp3car audio folk will be ecstatic.

I’ve just implemented a pulseaudio client to handle the stream. It’s still not on pulseaudio upstream because there is some clock-synch improving to be done, and also automatic detection and loading of the bluetooth module into PA.

@Divya: With BlueZ 4.46 only, the only way to make sure is using hcidump, since no client handles the stream coming to bluez. BlueZ will disconnect after a few packets transmitted because of that fact.

@snicker: BlueZ receives the encoded stream through it’s air interface and make it available to the applications through it’s application interface (a bluetooth socket). A client has to connect to that socket, decode the audio, and use that stream somehow (play, record, etc).

Wow. I’ve been looking for something like this for a while now. So BlueZ will now support a2dp streams from other devices? But there’s no implementation for what to do with the stream?
