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

Reboot

----

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
