Yesterday the audio was working fine on my Windows 10 computer, turned it off for the night and back on this morning and no audio. The AMD HDMI Audio Driver doesn't show up in the playback devices list. I have tried different HDMI Cables and a different HDMI port on my receiver and TV. I have updated to the latest driver 17.4.3 and before restarting I did see the HMDI audio driver in the list of playback devices and the audio did work for a moment but after reboot it was gone again. I tried uninstalling and reinstalling the driver multiple times with no success.
Since the day before no changes had been made that could cause this I verified no windows updates were installed at that time either.
Please let me know any suggestions you may have.
