<DIV><FONT face=Arial size=2>A few months ago, I set up Myth on my machine
(2.4.x kernel on Gentoo) and had lots of issues with sound.
Ultimately, I fixed it by loading the tvmixer module. I don't know why
that fixed it, but as soon as I loaded the module and restarted mythfrontend,
everything sounded good.</FONT></DIV>

<DIV><FONT face=Arial size=2>I had to wipe my drive (don't ask) and am now
running a 2.6.6 kernel. The new kernel made it very easy to get ALSA
up-and-running and I'm using it in Xine, mplayer, XMMS, and other apps.
However, when I set Myth to use ALSA:default, I got choppy video (lots of
prebuffering messages) and audio that wasn't quite right. It sounds
clipped. I played with the mixer levels, and no matter how low I go, there
remains distortion. I switched to /dev/dsp and /dev/adsp, both of which
work, but both of which have the same audio distortion. In addition to
adjusting the levels with my soundcard, I also tried to adjust the TV-Card's
mixer, by doing alsamixer -c 1. I can only adjust the level attached to
"Capture" and changing it doesn't have any effect.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>ALSA gives me great sound in my other apps and I'm
fairly confident that I have it set up correctly. I don't know what I'm
missing in Myth. I'd be okay with using OSS with Myth, provided I can get
clean sound. Any ideas?</FONT></DIV>
