With this card I can mute/unmute the headphones, but I'd like to be able to adjust the volume level on the headphones.

Obviously, the headphone volume control only makes sense when pluging the headphones doesn't mute the speakers. > > From what I have seen that could be done using the softvol plugin but I guess that it needs a specific pcm device for the headphones, which I don't seem to have.

Playing a bit with it I see that with Node 0x14 I can mute the speakers. But I don't know what to do with this...
