so, you have a ps3 hooked up to your system via toslink (optical spdif). your ps3 is set to output audio in DTS format ... how do you decode it and play it back on the speakers?
NOTE: there are a few ways to do this, but this is the best one I can come up with:
arecord -D spdif -t raw -f S16_LE -r 48000 -c 2 | ffmpeg -f dts -i - -f s16le - | aplay -r 48000 -c 2 -f S16_LE
ffmpeg uses libdca (libdts is the older name of the library), unfortunately gstreamer is based on the old library and doesn't exactly work.
gstreamer pipeline would look something like this (I couldn't get this working) :
gst-launch alsasrc device=spdif ! audioconvert ! dtsdec ! audioconvert ! alsasink
