The ivtvctl tool can do that:
ivtvctl -c audio=0xe9 for 48 kHz, 0xe8 for 44.1 kHz and 0xea for 32 kHz.
But note: I no longer support ivtv-0.7 and if you can I would strongly
recommend upgrading to kernel 2.6.18 or up, that way I can help you
debug better.

They're the same.

No idea.

Someone (must be MythTV) is still messing with the audio frequency.

Again I *strongly* recommend upgrading to 2.6.18/ivtv-0.10.x! This will
almost certainly solve your problems, and if you still have problems,
then I can help debug them.
