CX20549 (ctx5045) doesn't accept data on index 1 for output pins, as shown in the following hda-var transaction:
$ hda-verb /dev/snd/hwC0D0 0x10 set_amp_gain 0xb126 nid = 0x10, verb = 0x300, param = 0xb126 value = 0x0 $ hda-verb /dev/snd/hwC0D0 0x10 get_amp_gain 0x8001 nid = 0x10, verb = 0xb00, param = 0x8001 value = 0x0
