It may work well enough for you, but it may only partially work and you
may lack volume control for some sources because pcm is and input level
and the volume controls should really control the output level.

Take a look at the mixer(8) channels available and see if you have an
"ogain" mixer. If so, this is Output Gain and does exactly what Volume
does on other hardware. It is a master output level and control volume
over all.
