Sound device not producing any sound


After some problems with my computer, my onboard sound seems to be acting up. After rebooting into my newly working system (the Heatsink was not seated correctly and was overheating the chip) I wanted to play some music so I started xfMedia and there was no output. At that point I checked the levels via xfMixer and then alsamixer to ensure that neither the Master or PCM sliders were muted or down too low to be heard. Neither of them were (both at about 80% and unmuted). I have also installed another soundcard, but that one doesn't work well in linux either (doesn't boot up with a Master or PCM slider.) The chip is a SiS SI-7012, which uses the snd-intel8x0 driver.

Some possibly related information:

lsmod (only showing related entries):
Code:
snd_intel8x0           28316  2

(if you don't know - lshwd is a tool created for Arch that lists all hardware and their suggested drivers)

Anything else anyone needs, I will be more than happy to post - and thank you for taking the time to read this.

Check if /dev/dsp is present and active.

/dev/dsp is a symlink to /dev/sound/dsp, which looks 'active' - if by active you mean owned by root and accessible to those in the audio group, and permissions of 666.
