I think I suffer on the same issue, the only way for me to get sound is to open the terminal and to execute this:

sudo alsa force-reload

afterwards I get the sound, Everything is working than correctly, only the internal microphone volume have to be adjusted.

Skpe is than also working correctly with the the pulse audio mixer.

Is there a way to have script with the command at start-up after pulse is loaded? It will fix here the issue with detecting Alsa correctly.

It looks to me that Pulse does not detect the Alsa correctly

Thx for checking

BTW my output after the asla force-reload command was:
