the unmute command gave errors, but the set commands for pci and playback
did the trick.
I'm sorry to pester everyone with questions, but this is very helpful.
thank you everyone

That means that, in all probability, your sound card has already been
discovered and is already configured.

That's further evidence that the sound card is set up just fine. If it
then you'd have received an immediate error.

What you probably need to do is to unmute the relevant channels and turn up
their level controls. Assuming that you're using ALSA, give the following
commands a try (case is important):

   amixer set Master 90%
   amixer set Master unmute
   amixer set PCM 75%
   amixer set PCM unmute

Note that these are only example commands. The specifics on your system, or,
rather, with your sound card, may differ.
