Reinstalled Windows 7 - no sound working HDMI

Greetings. Windows 7, two monitors, one HDMI and I extend that one to a Samsung TV. Could get sound through HDMI monitor and the Pioneer AV receiver. Then tried to update to Windows 10. Worked for a week then quit. Called MS and they reinstalled Windows 7. Back in business except now I have no sound in the monitor OR the AV receiver. All driver software is up to date. Have tried switching between Realtek Digital Output and AMD HDMI Output as default, but get no sound. The Realtek will show sound moving the volume icon but the AMD doesn't show anything moving.

Another thing I noticed is that the Samsung TV used to show up in my display properties, but no longer does. Not sure if that's relevant or not. I use a Rocketfish HDMI interface to extend to the TV. I have changed nothing in the hardware set up/cabling etc. since the crash with Windows 10 and reinstall of Windows 7.

I sure would appreciate any help figuring this out. I've browsed everything I can find and none of the "fixes" I've tried works so far. Thank you.

Using AMD Radeon Graphics Processor (0x68B8) AMD Radeon HD 5700 Series - again, not sure if this is relevant, but the first time I tried a video after the reinstall, it wouldn't work based on the sound, not the video card. I can see video now, but no sound. Thanks.

Fixed it. I deleted the AMD and the Roktek drivers. Then rebooted and let windows auto install the windows drivers. Everything is working fine now. The AMD and Roktek drivers are no longer there.
