ati7790 hdmi audio override VIA onboard unless uninstall/reinstall VIA

TBH I'd be happy with sound from both HDMI and VIA onboard.

PC to HDtv via HDMI.

HDMI sound always overrides onboard VIA sound (v10_1200a)

If I want to use onboard, Device Manager: I have to uninstall VIA High Definition Audio then Scan for Hardware Changes, viola.

Reboot, must repeat process

Tried this, and killed all sound:
You can disable them by editing two registry keys.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\HDAudBus\Start=4

This value disables the High Definition Audio Controller in the device

manager > system devices, it needs to be disabled.

HKEY_LOCAL_MACHINE

\SYSTEM\CurrentControlSet\servic es\HdAudAddService\Start=4

This value

disables the High Definition Audio Device/ATI HDMI Audio Device. You

don't have to uninstall the devices first and this will also free up

an IRQ. After a reboot the devices will show a yellow exclamation

point but you can ignore that.

Thanks in advance

Setting default from hdmi to speakers does nothing until I uninstall/reinstall thru device manager

Please fill in your PC specs "My System Specs" so we know what we are dealing with.

What happens if you disconnect the HDMI cable at the PC?

I lose both video and audio
