Hello,

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?

cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.21.
