i have tried purge alsa-base , pulseaudio install again, reboot, still not working..

have tried blacklist module in /etc/modprobe.d/blacklist.conf, i've read in archlinux forum cause of similar problem, no luck

code:

# disable bluetooth  blacklist btusb    # possible soundcard bug  blacklist i82975x_edac

my sound card is

code:

is kernel problem? , how fix this?


btw somehow fglrx works worse fglrx-updates 12.10
fglrx works better fglrx-updates 12.04 --> sayin..

yea, kernel problem...what kind of update if didnt have deal ******** hardware not working anymore? have different hardware still same problem snd-hda-intel , although half-assed fix, if can roll 3.2 kernel holding shift when starting up, that'll fix audio (but knock stupid years old issue of suspend , randomly making hard drive slow death fixed in 3.5) in between 3.2 , 3.5
