Is there a way to transcode CD PCM streams into
DTS so that they can be played without having to
upconvert the signal to 48kHz?

A CD PCM stream converted to DTS would produce a 44.1khz DTS frame,
which of course would also not play on 48K-only hardware.
The sound playing application should be doing the resampling. I have
added support for this into xine. So, if it detects a sound card that
can only do 48Khz, xine uses high quality resamplers instead and then
outputs to alsa at 48Khz.
