Hi there, In Control Center, you need to open the Terminal, and type: alsaconfig. then just follow the prompts. Next open your mixer and you will see a drop down for settings. It should then show your VIA Chip. I have a Realtek ALC889A, and I get the same issue that your having until i complete these steps. You want to open ..preferences in the mixer. So,...Control Center>System> Terminal> alsaconfig and then ..preferences in your mixer. find your VIA, check or dot it, and you should be good to go.
