[mythtv-users] RE: nForce4 Audio on FC4, it plays some of the time...

Fri Nov 4 10:08:44 EST 2005

 Well I tried your start up script and your .asoundrc file and it didn't see
to work.
 I think I am missing something from the start up script. When KDE boots up
the optical port on the MOBO won't light up until I open gamixer and turn on
the IEC958 Playback button. After I check that box, the optical fires right
up. I just need to determine the setting that is changing and add it to the
start up script.
 So I tried booting into KDE without doing anything other then using the
scripts you provided and when I go into MythFrontEnd and set the device to
"ASLA:digital" and enable AC3 through the SPDIF, when I try MythMusic, It
can't open the device (See the log below). I get the same result with
enabling the IEC958 Playback button before going into the front end as well.
The "digital" device isn't found.
 I will have some time to play with it this weekend, so I might figure
something out, I am sure it is something silly. Silly yet frustrating..
