>Description:
My Sound Blaster Audigy 2 ZS works quite well but volume controls are completely non-functional.  Setting outputs.master, inputs.dac, outputs.master.mute, inputs.dac.mute in mixerctl is useless.  The values will change and stay where they have been set but they do not change the actual output at all.

emuxki0 at pci4 dev 7 function 0: Creative Labs SB Audigy EMU 10000 (audio multimedia, revision 0x04)
emuxki0: interrupting at ioapic0 pin 17 (irq 7)
emuxki0: ac97: SigmaTel STAC9721/23 codec; 18 bit DAC, 18 bit ADC, SigmaTel 3D
emuxki0: ac97: ext id 200<AMAP>
audio0 at emuxki0: full duplex, mmap, independent

>How-To-Repeat:
Install SB Audigy 2 ZS.  Try to change dac/output volume using mixerctl.
>Fix:
No idea.

 I have a ZS and see this problem too.  I don't think that there's an easy
 fix -- emuxki(4) uses ac97 mixers only; apparently, the ZS doesn't
 use them.  Proper Audigy support would require porting of FreeBSD's
 snd_emu10kx...
