I updated the Dektop Video drivers to 10.7 and suddely had no more system audio.
(Windows 10 pro x64, Analog XLR Out 1+2 -> Mixing Console -> Speakers).
Audio only worked in Media Composer and Adobe Premiere but not in Firefox, VLC, iTunes, etc.
Uninstalled and reinstalled several time, tried every possible config, but nothing worked...
I reverted back to Dektop Video 10.5.4 and everything works fine again.
Anyone else with this problem? Seems to be a bug.
Please look into this issue. Thanks!
