The title says it all. After a clean install of Intrepid the VIA 82C686A/B rev40 onboard sound card isn't producing any sounds at all. Here's some info:

I've made sure all the volume levels are at 100% in alsamixer and the sound card is enabled in the bios. Any ideas anyone? This worked fine when it was running Hardy.
