Enable the commented out part again in pci/ac97/ac97_patch.c:2043 ac97->flags |= /*AC97_HAS_NO_MASTER_VOL |*/ AC97_HAS_NO_PCM_VOL; to ac97->flags |= AC97_HAS_NO_MASTER_VOL | AC97_HAS_NO_PCM_VOL; The _only_ question is, whether the Master volume really does nothing, or has _any_ role. As mentioned, if it's really a dummy control, we should rather remove it to avoid confusion.
