Currently ALC662 doesn't suport amp mute for AmpOut in nids 0x02, 0x03, 0x04 (see block diagram in ALC662 datasheet page 3, does M correspond to mute?). The result is that currently mute for "Front Playback Switch", "Surround Playback Switch", "Center Playback Switch" and "LFE Playback Switch" mixer items doesn't work (tested on Asus P5GC-MX motherboard with 3stack-6ch model).
The solution I found for this is to mute the proper inputs in 0x0c, 0x0d, 0x0e audio mixers.
