Reading all day to find sollution.
Simptoms:
- in nvidia control panel -> change resolution -> philips hdmi enabled audio- listed and active, but in windows audio playback devices not listed so not able to set TV as default audio device
Soluton (as for me) :
- dovnload and instal latest Nvidia drivers (explanatio: on HDMI port graphic card is giving sound)
- go to control panel ->programs and features -> uninstal nvidia HD audio driver
- connect TV and laptop with HDMI cable
- go to device manager -> other devices -> audio device on high definition audio bus, here multiple devices with triangle listed
- right click on some of listed HD devices and chose update driver, navigate to automatic nvidia extraction folder (example: C:\NVIDIA\DisplayDriver\331.82\Win8_WinVista_Win7_64\International\HDAudio)
- instal for all HD audio devices listed
- tada, your sound is working!
