ALSA: HDA: Enable internal speaker on Dell M101z
commit 145a902bfeb1f89a41165bd2d1e633ce070bcb73 upstream.
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.
