AMD Radeon HD 6570 HDMI audio lost

Default AMD Radeon HD 6570 HDMI audio lost - 08-11-2017, 21:25 | posts: 1

I just updated my Radeon HD 6570 driver thru Auto Detect utility.
Previously had option to route audio to either desktop speakers via
AMD HDMI output from the Radeon card to Samsung HDMI input tv w audio.

Then when I selected "AMD HDMI Output" from playback devices I got window "The device is being used by another application. Please close any devices that are playing audio to this device and then try again". No other apps were open using audio/ AMD HDMI Output.
So thru control panel I uninstalled the driver which (obviously) killed displays on all three monitors- desktop vga & HDMI monitor & living room Samsung
HDMI input plasma.
Had a buddy connect w Team Viewer and install the original OEM disc driver
(my Safe Mode wouldn't allow installation). Now when I select playback devices window it shows "AMD High Definition Audio Device not plugged in".
... I unplugged/ plugged HDMI from the card to hub and both HDMI outputs
to both HDMI displays. Still playback devices window shows "AMD High Definition Audio Device not plugged in". I know the cables are good.

Downloaded 64bit driver but HD6570 may be 32 bit= Windows7 64 bit OS
may be in conflict? The oem driver is ver. 12-128(7/xp/vista) (8.93)(cat.12.1)

Afraid to try even a manual driver download again as since the Auto Select function installed wrong driver (no HDMI audio output) not sure which manual (older version?) DL would work to provide HDMI audio selection. I DO get HDMI VIDEO output to all displays but no audio.

Device manager next to the Radeon HD 6570 shows amber "! caution sign" indicating error? I just want to get the HDMI audio back. "It all worked flawlessly up to the driver update..." seems to be a common problem.

Suggestions? Thanks much.
