[clug] alsa config for MythTV (spdif)

In the last few months even after upgrading MythTV and Fedora (currnetly 
12), I have been getting these " WriteAudio: buffer underrun" messages 
in my Mythfrontend log which causes pauses during playback.

So I'm trying to review my ALSA setup which I admit I just copied from 
the Wiki, so if anyone has some advice I would be glad to hear it.

I'm using an on board nvidia sound card which I'm outputting my SPDIF to 
my AMP.

Note the current setup does produce sound and it seems good to me but 
perhaps if there is a way to optimise the buffers perhaps this might fix 
the issue I have with the buffer underrun.
