Volume Control Doesn't Work

If you are unable to control or mute your volume, you can try this solution:

Edit the alsa-base config file in the /etc/modprobe.d directory

 dcerouter_1:~# vi /etc/modprobe.d/alsa-base

Add the following code to the bottom of the file.

 options snd-intel8x0 ac97_quirk=hp_only


AC97 Quirk Option


The ac97_quirk option is used to enable/override the workaround for specific devices on drivers for on-board AC'97 controllers like snd-intel8x0. Some hardware have swapped output pins between Master and Headphone, or Surround (thanks to confusion of AC'97 specifications from version to version :-)

The driver provides the auto-detection of known problematic devices, but some might be unknown or wrongly detected. In such a case, pass the proper value with this option.

The following strings are accepted:

   default   Don't override the default setting
   none   Disable the quirk
   hp_only   Bind Master and Headphone controls as a single control
   swap_hp   Swap headphone and master controls
   swap_surround  Swap master and surround controls
   ad_sharing  For AD1985, turn on OMS bit and use headphone
   alc_jack   For ALC65x, turn on the jack sense mode
   inv_eapd   Inverted EAPD implementation
   mute_led   Bind EAPD bit for turning on/off mute LED

For backward compatibility, the corresponding integer value -1, 0, ... are accepted, too.

For example, if "Master" volume control has no effect on your device but only "Headphone" does, pass ac97_quirk=hp_only module option
