Hi,

there are some patches for alsa-lib (1.0.9rc2), we use them in Fedora 4. 
About mixer patch - some user had a problem with ICH6 and this patch helped.

Otherwise, we try to use dmix as the default pcm device in FC4, we have 
experimental ainit tool for run-time creation of ~/.asoundrc file with 
safely generated IPC keys for dmix/dsnoop/dshare plugins. Every feedback 
is welcome...

Ma.
