OK :-( So I made another ac3 files recording Pro-7 and using ds.jar: ./ac3dec -6 -R /video2/esa1.ac3 2.0 Mode 48.0 KHz 448 kbps Complete Main Audio Service Using PCM device 'iec958:AES0=0x0,AES1=0x82,AES2=0x0,AES3=0x2' And I can hear in only in stereo... maybe the -6 option is not the right one? So I take a DVD with which I am really sure have 5.1, with ds.jar I demux it and with -R I can hear, but only stereo and with the other option I can't??? > the spdif device is hw:0,2. > i guess ther is an option in mplayer to specify the pcm name for > ALSA. use "spdif" there instead of "hw:0,2". Well: mplayer -vo null -ao alsa9:spdif -abs 1 -channels 2 gives me: Cache fill: 0.00% (0 bytes) MPEG-PS file format detected.
