[mythtv-users] SPDIF and HDMI

[Mitch Gore]

yes you have to enable IEC958 in the mixer.

in terminal "alsamixer" use the arrow keys and move over to IEC958 and push
'm' to unmute them, there maybe a bunch of them or just one.  My sound card
have about 5 differant IEC's i just played with them until i heard sound.  A
good way to test is to let mplayer play something with digital audio in the
background to do this use...

mplayer -ac hwac3 filename

Now mess with the switches until you hear something.
