[mythtv-users] audio issue: difficult to hear voices over background sound (like audience clapping)

I'm having some sound issues with my MythTV. It is usually ok, but when
there is a lot of noise, like an audience clapping or something, it is
difficult to hear what people on screen are saying. It seems like the
background noise is overwhelming the speech. If I watch the live feed
(ie. not routed through Myth at all, coming straight from cable in the
wall) the sound is balanced much better.
I have tried messing around in kmix and alsamixer, but there are just so
many options and sliders. I have fiddled with various ones but the only
results I have seen so far is sound or no-sound, with no ability to
change anything except volume.
I have an nForce3 motherboard with onboard sound. I run a splitter
cable that plugs into the sound out on the motherboard and splits into a
Y with red and white audio plugs that go into the TV.
One strange thing to note: In order to get sound at all, I have to turn
on 4 or 6 channel audio in kmix. I thought that I had it plugged into
the wrong audio-out (like rear out) on the motherboard, but apparently
not. What color output should I plug into? I think there is red,
green, and purple. I can't remember just now which I'm plugged into,
but if I try any of the others, I get no sound.
Any help would be appreciated. Also, if you have an nForce3 alsactl
restore file, I would definitely try it out and see if it helped at all.
Fedora Core 5, 2.6.16 (I think...)
nForce3, all standard drivers
Fedora Core 5, 2.6.16 (again, not sure...)
