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
