After upgrading to windows 10 from 8.1 my msi gt70 notebook with gtx770m card is not passing audio through the hdmi. The sound preferences don't show the TV as a playback device. And it isn't showing up under audio hardware in the device manager. The gtx770 control panel has audio through hdmi enabled.
Opening up the device manager, the tv shows up as ageneric pnp monitor under displays and as lg webos tv under digital media devices. Under details for lg webos tv the status for No connect sound is <true>.
Any help would be greatly appreciated.
