[PATCH] ALSA: HDA: Enable internal speaker on Dell M101z

[David Henningsson]

BugLink: http://launchpad.net/bugs/640254

In some cases a magic processing coefficient is needed to enable
the internal speaker on Dell M101z. According to Realtek, this
processing coefficient is only present on ALC269vb.
