I'm doing what I think you want -- default output from PulseAudio is bluetooth (name is a2dpd on my system). Although my ALSA default is still hw:0,0, but doesn't have to be. I'm appending my default.pa and .asoundrc files. (I'm not suggesting these as best practices...) Bluez-utils version 3.19, PulseAudio 0.9.6 (still haven't been able to get 0.9.7 to configure; I've been concentrating on bluez-utils.) Unfortunately for me, this setup hasn't been very successful, talking to a Motorola HT-820 headset sent from a Dell type 355 (Broadcom BCM2045) builtin HCI (Bluetooth 2.0). In the most recent test, about 70% of the music was just lost, as if the packets were trashed beyond the ability of the 2nd layer protocol to retransmit them. Maybe the neighbor was using the microwave oven :-) (not really, it's at least 30 meters to the nearest one), but it works almost perfectly minus PulseAudio, the player (xmms) writing directly on the ALSA device. Somehow I think the problem isn't trashed packets, it's problems sending them out. Since I've sort of figured out how to use bluez-utils-3.19 (just in time for 3.20 to come out), I'm going to be working on PulseAudio in the next few days. I'm really interested in news of other people's experience with PulseAudio and the current bluez-utils -- does it work for you? James F.
