I have an oldie but goodie Radeon HD 5870 Vapor-x
I have installed the latest drivers, I think.
Display driver: Advanced Micro Devices, Inc. - 2/26/2016 - 15.301.1901.0 - Signer Microsoft
Audio driver: Advanced Micro Devices - 1/16/2016 - 10.0.0.2 - Signer AMD
Also, this morning my board mfg. [MSI] downloaded latest AMD chip drivers.
Both devices working properly per device mgr.
Windows 10 Home Version 2004 - Installed 7/26/20 OS build 19041.508 - Experience pack 120.2212.310
No problems w/video using displayport but my audio is the problem....
On boot audio returns to the onboard (that's not working either, lost it about a month ago, IDK why!).
In the audio selection, I only see the onboard Realtek HD audio, no AMD.
I look at device mgr. the AMD audio device is there and "working properly".
If I uninstall the AMD audio drivers, then rescan for new hardware,
then it becomes available again and works fine, till next reboot.
Any help will be greatly appreciated.
