After Kernel Update, Jittery Sound


I updated my kernel to (possibly) solve some problems with my Ethernet connection. So far it all seems to be working.... but now I am having audio problems.

Running built in ALSA drivers compiled as a module, running kernel 2.6.25-gentoo-r7.

The problem is, I used to have any 2.0 audio (i.e. music playback) duplicate across all channels; in my case 4. I made no changes to my kernel config, and after the update the audio sounds jittery when any other system activity happens. I found the problem to be in my .asoundrc which look(ed) like this:
Code:
pcm.!dmix {
   type dmix
   ipc_key 1024
   slave {
       pcm "hw:0,0"
       channels 4
       period_size 1024
       buffer_size 5120
   }
}
pcm.!default {
   type plug
   slave.pcm "dmix"
   slave.channels 4
   route_policy duplicate
}

I tried running
Code:
alsaconfig
again, but that didn't fix it. Removing my .asoundrc file fixed the problem, but now I no longer have the sound over all 4 channels. Under this configuration, I do still get 4.0 surround sound through VLC watching movies.

Now if I go into alsamixer and set it to duplicate the audio over all channels, I do indeed get audio from all channels. However, if I then go to watch a movie in VLC it does the same thing, duplicating all audio over all channels, so not really bing surround sound.


Any suggestions?

Thanks
Brandon
