Surface Pro 3 audio problems w/ Win 10 10130

[Sunstorming]

Just installed Preview 130 on my SP3. Works great except one huge thing: No Sound! Netflix for example will not play movies because of this. Sound looks OK in the device manager.

Interesting note: Plug in headphones, sound is fine. docked to keyboard or as a tablet, no sound, again headphones work however. Any ideas?

I just restored the system to 8.1 ... which was painless and only took a few minutes, so kudos to the Win 10 team for that. Working like it should now.
