    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
