Surface Pro 4 - Internal microphone not working after Windows 10 Anniversary Update.

I have just installed the Anniversary Update on my Surface Pro 4. The internal microphone no longer works. I have uninstalled and reinstalled the Realtek High Definition Audio(SST) drivers, but that does not help. If I plug in the headset, the mic on the headset works fine. The internal mic array is set as the default.

The fast start option seems to be creating a lot of issues similar to this with the anniversary update.  I would try disabling fast start which is enabled by default in power settings.
