I have onboard sound, it's been working perfectly fine in Arch. The other day I took apart my computer to move it into a new case, dropped a screwdriver on the motherboard a couple of times, straightened a pin that I noticed was bent on the front panel audio connector (which I wasn't using), and when I hooked everything back up and turned the system on, I no longer heard sound. I didn't get any error messages from the sound system, and when I play something in, say, Amarok, everything looks normal, except for the fact that no sound is coming out of my speakers. So I suspect I physically damaged the part of the motherboard responsible for playing sound.
lspci still returns the name of the onboard device, though, and dmesg doesn't report anything different from what it normally reports about the device. Is there anything else I might try to see if there's a software solution to this?
I'd like to fix the onboard sound, but I thought that might not be possible, so I put in a cheap PCI sound card. lspci detects this too, but when I plug my speakers into that card's line out I also get no sound, although again everything on the software end seems to be fine. I tried disabling the onboard sound in the bios but the system still doesn't seem to detect that I want to use that card.
So, if anyone has any thoughts on what I'm doing wrong with the PCI sound card or (preferably) a way to try to fix the onboard sound, please post.

Have you run "alsaconf"? It could be your PCI sound-card isn't configured in ALSA yet.
Have you checked whether the line-out is muted? You could for example by "alsamixer" adjust sound levels.
If the on-board sound-card is disabled, there shouldn't be any other card for ALSA to pick up. Otherwise you need to check in /etc/rc.conf which card is picked up as default, in other words which module is put first in line.
Dropping screwdrivers on the motherboard isn't a very good idea. Even static electricity could severely damage components.

Use index=0 to specify the default card - see wiki article.
