[ALSA] emu10k1 - Fix inverted Analog/Digital mixer switch on Audigy2
On Audigy2 Platinum, the Analog/Digital mixer switch is inverted. https://bugzilla.novell.com/show_bug.cgi?id=396204 The patch adds a simple workaround. There might be another device requiring a similar fix, too (or fix for audigy2 generically), but right now I fix only the known broken one. Signed-off-by: Takashi Iwai <tiwai@suse.de>
