17 with mplayer I used to use this command to get spdif output:
18 mplayer -afm hwac3 blah.avi
19
20 also, with the old (2.24?) gnome alsa mixer, I found I had to add the
21 spdif or IEC device (can't quite remember), and although it was a
22 slider, it only worked in an on or off fashion.
23
24 Not much help for you I know, but I can't run the same mixer anymore to
25 find out.
