I have a PC soundcard going into an amp/receiver (coax digital out
from the PC) how do I adjust the volume for optimal sound? Since the
PC and the receiver each have their own volume control?

Start out with control at about 2 o'clock, and adjust equally in order to
have desired maximum volume.

The sound card probably has two volume controls all by itself, one for wave
output (i.e., not MIDI or CD or Line In) and one master volume control. Same
basic idea follows - have both set proportionately the same and adjust
together for maximum desired output. Use the volume control on the receiver
for your main systemcontrol.


Similarly, if I have a powered sub (with it's own volume control) and
the receiver has a volume control for the subwoofer, how do I balance
the volumes for the best quality sound?

Same basic idea.

Do I turn the volume all the
way up on the sub itself and just use the volume control on the
receiver or vice-versa, or some combination of both?

Split the difference.

I've always wondered about this. Could anyone shed some light on this
topic?

One gets a snout full of this kind of thing doing live sound. If you try to
keep all controls at similar proportional settings, the system is just
easier to manage.
