I am trying to isolate a 'lag' in my Thinkpad sound (kernel 2.6.7-1.494.2.2) in FC2. When I first boot, and atempt to play a sound, there is a 'lag' as if Alsa is attempting to start but having difficulty. I am getting the following error in the system log and am not sure if it is related, but I figured I have to start somewhere.
cs46xx: failure waiting for FIFO command to complete
If found
this guide that mentions adding the following to /etc/modules.d/alsa in Gentoo.
options snd-cs46xx thinkpad=1 index=0
The problem I am having I am having is that this file does not exist in FC2. Where would I put this option? I tried /etc/modprobe.conf and it did not fix the logged error or the problem. Any ideas?
