<font color='#000000'>I've answered my question from another post about whether the Audigy sound card can send multi-channel output digitally to the Yamaha. In a word, no. It will only send 2 channels digitially. They show up on the receiver as PCM at 48khz - apparently the Audigy up-converts my 44.1 khz WMA files to 48 khz.
Does the SPDIF spec allow for sending more than 2 PCM channels?</font>
