.Ar dev ,
1997-01-10 06:33:13 +00:00
the optional left and right channel settings of

.It +rec
adds
.Ar rdev
to possible recording devices
.It -rec
removes
.Ar rdev
from possible recording devices
.It =rec

The above commands work on an internal mask. After all the options
have been parsed, it will set then read the mask from the sound card.
This will let you see EXACTLY what the soundcard is using for the
recording device(s).
