I was thinking of this coming out soon, but didn't expect something so early. the CSR based headphones seem to work pretty good so far. We have some minor issues on the AVDTP protocol level, but they are fixable. The current big issue are the Broadcom based headphones. While CSR seems to be quite forgiving if you send data too fast (actually I think they use flow control in the baseband to slow us down), the Broadcom ones are not. We have to send the next SBC frame at the exact time slot. Otherwise the audio sounds too fast or frames are skipped. If you have any ideas on how we can improve pcm_bluetooth.c (yes, that handling is inside the ALSA plugin), I would like to know.
