That was one of the things I've tried, but i get the errors along the
lines of pcm_dev_open : no such device 51to20.
I've looked into the sink source, but it's too alsa-specific, i have no
clue as per what's going on there...
btw, my alsa is self-compiled (ubuntu's version has some bugs to it),
could that be causing any trouble?
