 * As of kernel 2.6.17, some users report a missing master volume control (e.g., with the T60p and Z60m), as described in this thread: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg17089.html
 : As of ALSA 1.0.13 the master volume has returned. Download the latest modules from your distrobution to fix this problem. Otherwise as a temporary fix add model=hp to the snd-hda-intel module option. This will return the master volume control to your control.
