Q7: Will PCM sound output through S/PDIF be just 2 channels even with
different analog output channels?
Answer:
The S/PDIF protocol specification (IEC-60958) can only carry 2-channel PCM
data or non-PCM AC3/DTS data. So, when a user selects PCM output for
S/PDIF, the Xonar sound card will always deliver 2 channel PCM data through
the S/PDIF output port. For attaining 5.1 channel surround sounds, you can
select Dolby Digital Live encoding output from the S/PDIF out menu, which will
allow the Xonar Essence STX to deliver 5.1 surround sound for DVD movies,
and even stereo music.
