ALSA: usb-audio: don't hardcode gain for output channel of Presonus Studio 



On the 1824c output channel 4 left/right is the S/PDIF output,
so this needs to be able to be set.

I'm guessing that for the 1810c since it has no output channel 4,
it does not matter what the gain value of this channel is set to.
