Takashi Iwai 4d4e9bb339 ALSA: hda - Add digital beep playback switch for STAC/IDT codecs 
The digital beep widget may have no mute control, and always enabling
the beep is ofen pretty annoying, especially on laptops.

This patch adds a mixer control "PC Beep Playback Switch" when there
is no mixer amp mute is found, and controls it on software.
