Using it with multichannel data is possible only by compressing the audio so that the compressed stream has the same bandwidth as an uncompressed stereo stream; the compression algorithm is either Dolby Digital or DTS. > Can this be done in linux and if so which alsa device and options should > I use? Run "arecord -l". There should be a separate device for the digital input, which should be available as "hw:D2,1". You have to pretend to record two channels, and the resulting file will not contain PCM audio but compressed data. I don't know you can decode it; probably with ffmpeg.
