Hdmi Audio Not Working. Anyone have any idea of what's going on here? The problem could be anywhere from your PC, the HDMI cable, to your monitor or TV.
Everything works with other devices, just not my PC. Is your HDMI device not showing in sound playback devices in Device Manager? The steps on how to change the audio output setting vary depending on your source device.
The movie was displayed in the TV but the audio was still coming through laptop's inbuilt speakers.

Check your device manual or contact the manufacturer for further assistance. Within NVIDI control panel > Set up digital audio > HDMI it shows only "No audio capable display available." Tried so far: Install drivers again through normal NVIDIA software flow Used DDU to completely uninstall all. * I have turned off/on audio devices in device manager - not working. Sometimes HDMI audio won't work due to your audio drivers.
