I'm no longer able to get audio though HDMI when upgrading to 21.2.2. I have resolved this by rolling back to the WHQL 20.11.2 drivers as a temporary fix. I tried rolling back to the previous Optional version of the drivers (21.1.1) but the issue persists.
I've tried cleaning up with the AMD Cleanup tool in Safe Mode. I've uninstalled with DDU.
Restarting the system I have audio again. Installing the drivers I still have audio. Doing the necessary restart following the installation results in the system not detecting the HDMI audio cable as being plugged in.
I have tried upgrading the display driver only by extracting it from 21.2.2 and directly installing following the complete clean installation of 20.11.2. This again breaks the audio output. I have tried manually updating the audio drivers only and this doesn't resolve the issue.
When trying to troubleshoot the audio issue I have several AMD HDMI devices to try and troubleshoot/select with the Windows Troubleshooter. I believe the issue may lie in that on re-installing the new drivers, a new audio device is created. I can't figure out a way to remove the historical devices. Device Manager doesn't show up these multiple entries. I believe this may be a reason that rolling back to the previous Optional Driver version is not possible
Any help would be greatly appreciated.
