Need to get audio working on Osprey 440 card.
http://www.viewcast.com/pages.asp?page=osprey-440
The card is bt878 based, and ViewCast says it is supported on linux
however not something they support. Audio is not detected by default, but
does how up when you do a modprobe snd-bt87x load-all(see below). However
I have not been able to pull audio from the card (only get high pitched
noise). Bid may require patching bt878.c if modprobe options don't work.
Only mono support is required.
