Looking for updated or available HDMI audio driver

Question asked by pd1701fmv on Mar 14, 2020

System info: Desktop PC custom, HDTV Vizio E3D420VX 1920x1080 @ 60Hz

CPU: AMD Phenom II 965 .   Memory: 8 Gig    Motherboard: ASUS M4A89TD PRO USB3.   BIOS: 2001

(2) 1024 Meg ATI AMD Radeon HD5750 graphics cards. Catalyst 15.7.1

Antec TP650 power supply. Windows 10 PRO  64 bit Ver1909 upgraded from Windows 7 Ultimate.

RCA RT2911 Home Theater system.


I am not able to select 5.1 surround for HDMI speaker output, it defaulted to Stereo and the 5.1 selection is grayed out. The 5.1 worked fine in Win 7 before upgrading to Win 10. I am hoping a updated or compatible HDMI speaker driver will solve the issue. I have updated all drivers for the motherboard. I reached out to MS Quick Fix, the issue could not be resolved, the suggestion was to contact the manufacturer for a driver. Any driver experts for this issue?
