interesting, because that explicitly both unmutes the audio and sets
the input.  there's really not much (if any) more that can be done
to enable audio from bktr(4).

hmmm, try adding '-H 0' as well, maybe it messing up /dev/dsp when
trying to detect what it is.

also try with 'asource=intern' instead of 'asource=tuner'.

if it doesn't work after trying the above, could you please post the
exact command and screen output?  I wrote the bktr and oss import
modules for transcode, and would be interested in fixing them if
needed.
