i have tried to purge alsa-base and pulseaudio then install again, reboot, but still not working..
i have tried to blacklist some module in /etc/modprobe.d/blacklist.conf, that i've read in archlinux forum is the cause of the similar problem, but no luck
Code:
# disable bluetooth
blacklist btusb
# possible soundcard bug
blacklist i82975x_edac
my sound card is
Code:
$ sudo lshw -c sound
