Can I use the card to capture the raw SPDIF data on the Raspberry Pi?
I know that the Raspberry Pi is not powerful enough to do any DTS or AC3 decoding of 5.1 audio streams in software (according to the manual), but I would like to use the Raspberry Pi to capture the compressed DTS or AC3 stream in a file.
Example command line(*1):
arecord -Dspdif -f dat -t raw | spdifextract > /tmp/file.ac3
Thanks in advance!
(*1) spdifextract can be downloaded from http://forums.gentoo.org/viewtopic-p-4472816.html#4472816
