I can't seem to be able to play any sound. The sound device is recognized but neither headphones nor speakers will produce anything and there's an error when trying the speaker properties advanced test sound button.

I have the latest driver from https://www.asus.com/Notebooks_Ultra..._T100/#support (freaking annoying non-URL scripted website) - I have the 220 bios, assuming installation completed. https://www.asus.com/support/Article/563/ is facepalmingly useless in this case and I can't find the spot that tells me the BIOS version. I also installed the latest direct x redistributable.

Anybody else having this problem?
