Hi, Running fairly uptodate Sid. In the past (most recently, several months ago?) I've successfully used a bluetooth headset; it no longer works. The headset connects (it shows as connected in the Gnome bluetooth applet, and I hear the various tones / beeps from the headset that it uses to signal a connection), but the audio process trying to send it sound just hangs, and no sound comes from the headset. It remains connected until I kill the process.
Details and logs: The headset is a Plantronics Voyager 510, and the bluetooth adapter uses a Broadcom chip, supported by the kernel. From lsusb: Bus 002 Device 002: ID 0a5c:2121 Broadcom Corp. BCM2210 Bluetooth My .asoundrc: pcm.bluetooth { type bluetooth device 00:19:7F:40:06:2D profile auto } [I've tried both with and without the 'profile auto' line, and I've also tried a plug / slave
