For some reason the setup_ad2p() did both the SBC and MPEG configuration. Adding a test for the mode solves the issue, probably there was a buffer overflow or something bad. playing with SBC and MPEG works fine now, meaning that the negotiation works well depending on the payload. but when I try to go back to PCM/SBC the second time I get the following assert in pulseaudio (see gst log below) E: module-bluetooth-device.c: Assertion 'u->write_memchunk.length == u->block_size' failed at modules/bluetooth/module-bluetooth-device.c:1519, function a2dp_process_render(). Aborting. I'll let you debug this one, should be easier :-) Other things I noticed: the volume is much higher in passthrough mode, maybe we need to find a way to set the volume on the headset to match the volume used for PCM. Also I heard some high-frequency modulations, typically coding noise, maybe there's still something fishy during the mp3 decode part. -Pierre [gst-plugins-good]$ gst-launch --gst-debug=pulsesink:5 filesrc location=~/AURAL/Audio/theTest-320.mp3 ! flump3dec ! pulsesink device=bluez_sink.00_0B_E4_94_31_9D Setting pipeline to PAUSED ...
