So I was thinking of picking up a used small form factor PC to dedicate to a HTPC. Seems there's plenty of inexpensive options out there but then I noticed some, such as a Dell Optiplex 760, don't have digital audio output.
So question: is there a recommended inexpensive USB>spdif converter? I don't need a full sound card, just a converter. Are they all multi-channel dolby compatible or is that something I have to be careful about?
