No Sound from Intel Display Audio with Pentium G3258

HP Recommended
HP EliteDesk 800 G1 Ultra-slim PC
Microsoft Windows 10 (64-bit)

I replaced the original CPU with Pentium G3258.


Everything seems to be working fine except audio from Displayport-to HDMI cable to monitor.

Device Maneger shows all devices working properly, including "Acer S231HL (Intel Display Audio)<Audio inputs and outputs" and "Intel Display Audio<Sound, video and game controllers".


However, Default Format<Advanced<Acer S231HL Properties is greyed out.

When I play "test", it appears as if sound is played with volume level going up and down, but no sound from the display speaker.

I updated to the latest Bios, installed Intel Chipset Support and Intel Graphic Drivers.


I am wondering if the motherboard only supports i3, i5 and i7.

Any suggestions would be appreciated.
