About the time this was committed, I haven't had audio output on either
of my Myth systems. Been busy with work and stuff lately so I haven't
had much time to look at it, but I have been troubleshooting it the last
couple of days.
Kevin, what kernel version and alsa version do you have this working
on? It may help me track down my problem. I am using kernel.org 2.6.7
with patches and alsa 1.0.3 that comes with FC2.
If I come up with a solution I will send a patch as a few others on the
users list have also report troubles with the 2.6 kernels.
