I know this is really a moc (music on console) question but thought I would try here anyway because the moc community is not that active. I got bluetooth all set up and connected to my headset. I can play music on them via strawberry music player but it will not work on moc. moc will play on the speakers though so it is not a case of moc not communicating at all but just with the bluetooth headphones.
It should be possible to redirect non-Pulseaudio-aware applications using padsp, e.g.
padsp moc
$ padsp -h
/usr/bin/padsp - redirect OSS audio devices to PulseAudio
/usr/bin/padsp [options] application [arguments]
options:
-h show brief help
-s <host>[:<port>] contact a specific PulseAudio server
-n <name> client name to report to the server
-m <name> stream name to report to the server
-M disable /dev/mixer emulation
-S disable /dev/sndstat emulation
-D disable /dev/dsp emulation
-d enable debug output
