Hi Could you send me "bluetoothd" log? Thanks Chanyeol,Park -----Original Message----- From: linux-bluetooth-owner@xxxxxxxxxxxxxxx [mailto:linux-bluetooth- owner@xxxxxxxxxxxxxxx] On Behalf Of pl bossart Sent: Wednesday, September 08, 2010 10:35 AM To: linux-bluetooth@xxxxxxxxxxxxxxx Subject: MP3 over A2DP issue Hi, I have been doing some experiments to extend PulseAudio to support compressed data, so that the audio routing is simplified a great deal. I've already completed the work for AC3 passthrough over SPDIF/HDMI, works fine and the concept holds water. Now I am trying to send MP3 over A2DP through PulseAudio. I removed SBC encoding, detect mp3 frames and handle timings, now I am almost done and of course I am stuck with a stupid issue. I can't seem to open an MP3 connection to my Nokia BH-103 headset, for some reason the BT_OPEN request fails. Here's the log I am getting.

SBC connections work fine with gst-launch filesrc location=~/AURAL/Audio/viol-1mn.wav ! wavparse ! sbcenc ! a2dpsink device=00:0B:E4:94:31:9D So is there something wrong with this specific headset, am I doing anything wrong in the configuration? And what can I do in terms of instrumentation to find the issue? Or is it an issue with a bad seid reported by the device? When I use the SBC seid in the BT_OPEN request, the open works fine. As soon as I use the mpeg seid, things go south. Bear with me, I am far from my audio comfort zone here. Any pointers would be appreciated.
