For alsa, use ... uhh.. forgot it. "asset" or "sset" or something.
For OSS, use "setmixer", also "aumix" can be used from command line.
However, OSS-compatible mixers can not completely control ALSA, so if you
use the latter, it's better to use ALSA-specific mixer.

Yes, at least aumix and that "sset" (or something) allows doing that, not
sure about setmixer.

>c.) Is it possible to record a TV show without hearing the audio?

It depends on your sound card: can it record sound without outputting it to
the speakers? Or maybe you can just unplug the speakers. I think it should
be possible with most soundcards.

Or if it is BT878-based card, you might succeed using btaudio module (ie.
capture sound directly from TV-card and not via soundcard, but at least
with my TV card it doesn't work).

man v4lctl. Or use xawtv interactively.
