"Ah, so assuming my sound card only supports 48KHz, that would explain
why the myth code is resampling the output. Is there some definitive way
I can see if my sound card (mb audio VT8233) supports output at the
44.1KHz sample rate? Seems like that's the what this is coming down to... "
You could try to ask the folks at Via. Yeah, like they'd ever answer.
Seriously, Via is well known for sound chips which support 48KHz only.
Despite what modinfo and their web-site documentation show, 48KHz is
pretty much it for them. Try googling "Via" and "bit perfect audio" to
see what I mean.
I spent weeks trying get a Via mobo (and sound chip) to feed 44.1 KHz
out the spdif. Finally threw in the towel and bought a Turtle Beach
Riviera for about $20 to $30. It "just works."
If you want your CD's to sound right, ie., not up-pitched about 10%,
then you will have to get a new sound card. To my knowledge, there is
no alsa, jack, mythtv, or other way around it.
PS: Just a side note, I think it's MythTV telling alsa to re-sample,
not MythTv re-sampling.
