not sure how to answer your question.

so i created the ~/.asoundrc file with:
pcm.S9bluetoothraw {
   type bluetooth
   device 00:0D:FD:23:1A:DE
}
pcm.S9bluetooth {
    type plug
    slave {
        pcm S9bluetoothraw
    }
}

and then from audacious I tell it to use ALSA Output plugin for it's
audio system and set S9bluetooth as the audio device.

I use pulse audio at my home computer and it just works, no issues.
I created the asundrc file and issue the "pactl load-module
module-alsa-sink device=S9bluetooth" command every time I want to use
it and used pavucontrol the first time to configure it to use shared
outputs.

But on my work computer shared output won't work and if I start
sending audio out to the S9 and then another application (say Pidgin)
sends audio everything crashes. That's why I'm hoping to use just
audacious with ALSA.

Do you see any other solution I could try?
