The first thing I'd check out is alsamixer, as all the modules appear to be loaded. There is a typo on your 3rd step. Module should be snd-via82xx, not snd-via-82xx. That aside, open alsamixer as user, as below, and check for sliders that may be down at zero, or may be muted since the updates. Typical controls are, Master, PCM, Front, CD. "M" key toggles the mute/unmute. alsamixer -D hw:0 All the best.
