I'm experiencing crap sound preformance from my ALC 850/880 chipset.
I'm first wondering if their is a way to set the model other than the
/etc/modprobe.d/alsa-base.conf file? Can I try different models
without rebooting? So far I've tried the model 6stack, since that
sounds like what I have on my motherboard. Furthermore, does anybody
have any ideas on what else I can do so that my computer can sound at
least as good as my $20 coby mp3 player?
I've tried both driver version 1.0.21 and more recently 1.0.23, with
no improvment in sound.
Advanced Linux Sound Architecture Driver Version 1.0.23.
Compiled on Nov 26 2010 for kernel 2.6.32-5-amd64 (SMP).
Advanced Linux Sound Architecture Driver Version 1.0.21.
