1) ALSA seems not happy with the mixer

2) it looks like you have the HDMI port disabled (I don't know if this is relevant only for VIDEO out, though). If you use it as audio out, I remember somewhere having read that the audio is enabled ONLY if the video is; so, worth a check.

3) your sound levels seem to be 0 (zero, not 0dB)

Have you tried changing (and then reverting, eventually) some audio parameters? Just to see if the defaults, for some reason, are incompatible with your actual setup.

I'd first try the volume type => Software, then back => Fixed (0 dB). Maybe a reboot between the changes is necessary, cannot tell for sure, but it isn't hard to find out.

Hope this helps a little more.
