Generally if you run into this problem, it's one of two things:

1. `alsamixer` hasn't been used to unmute the levels. After configuring
it, be sure to run 'alsactl store' as root and make sure the 'alsasound'
service is in the default run-level (`rc-update add alsasound default`
as root), or...
2. Try adding these to your user's ~/.asoundrc file:

defaults.ctl.card x;
defaults.pcm.card x;

Replace 'x' with the numeric index of your card (which you can view in
alsamixer using F6). If the order of your cards changes on boot, you'll
need to tell the module controlling your sound (snd_hda_intel is common)
to set its index in a file like /etc/modprobe.d/alsa-base.conf, with
lines like `options snd_hda_intel index=1` or something similar.

Others have done a far better job explaining this than me. Our own guide
on our wiki [0] and Arch's wiki [1] should be adequate to get you going
fairly quickly. Just Ctrl+F "default" to find what you need. Assuming
you don't have exotic hardware, this can be fixed in 15 minutes or less.

Hope this helps.
