any update on audio for videos?

Can someone recommend USB Audio Card with Optical or Coaxial output what will work with Raspberry Pi on Raspbmc ?

Currently I have sound issues. Pi is connected to old Sony TV via HDMI and then receiver. Sound quality is bad due to old sony tv.

I would like to connect Pi directly to receiver.

I bought this http://www.ebay.it/itm/Turtle-Beach-Audi...dd5c#rpdId and works like a charm.

It's proving a bit difficult at the moment. On the bright side I managed to make AudioEngine/external usb sound cards support configurable. Need a bit more testing and if stable you could see it merged into Release.

Got some ways with this guide, no sound yet, though.
Cambridge DacMagic works nicely off laptop running ubuntu 12.04.
It also seems to get detected on the Raspi, pactl gets me the output below.

s7mx1, you mentioned to harmenzon that sound card might be muted, since it has no mute function in itself, and it works off another computer, would the muting be in the software somewhere, and if so, how do control it?

Code:

keep ourselves posted! I'm looking forward to watching movies on the rasbpi!
