Well, the problem is that no such list exists right now, I didn't keep
track of whenever Function .1 can do audio or not in bttvs card database
because bttv doesn't care, it does video only ...

So we'll have to build a whitelist from scratch from user feedback, and
maybe add a insmod option so you can ask the driver to grab the device
even if not whitelisted for easy use.

I know it works with my wintv (0070:13eb), but thats it :-/
