I have dual monitors on an XP SP2 system: one connected to the VGA port, the other on the HDMI port. Normally analogue sound is chosen but I can fiddle with the device drivers to get sound on the HDMI channel. But when the system is rebooted, it reverts to analogue. I would like HDMI to be the default. How do you do this?
The two drivers involved are (1) AMD High Definition Audio Device which appears to control HDMI and (2) Realtek High Definition Audio controlling the analogue.
The controlling software is the Catalyst Control Center
