Subject: [PATCH] regression 2.6.35-rc1+ hda realtek missing beep 10ec0883

From: David Fries <david@...es.net>

The PC-Spekaer Beep control worked in 2.6.34, but not 2.6.35-rc1, this
is the patch that modified that behavior.
"ALSA: hda - Add parse customize define function for Realtek codecs"
regression in commit da00c24493bf6ae3772dfe7343dca033ebc75955.

My patch restores both the Beep volume and mute.  I'll let someone
else determine if this is the correct solution or not.
