Would you buy or use a stand-alone mixer where the only way to control
total output would be to change the setting for one output, then
rebalance all the others against it, and then iterate until the result
is correct?

Is this an intermediate step to the full functionality of a $29 Radio
Shack mixer, or a limitation of just one audio driver, or maybe the user
interface for ALSA is broken right now?

Is it planned to leave Linux audio in this state?
