OK, I unexpectedly had a little time to work on Bino, and I implemented
this:
http://git.savannah.gnu.org/cgit/bino.git/commit/?id=7dc2939801a53b10b50333b5de14480a6c4a335c

You can select an audio device via command line or via
Preferences->Audio.

However, I cannot test it meaningfully since I don't have multiple
audio devices.

Please let me know if it works for you.
