Okay some info on my setup I have onboard HD4200 w/ HDMI out crossfired with a 3450 for extra power... luckily the 3450 i have has an HDMI out as well. The reason i crossfire instead of using the discreet by itself is becase I want that little extra power, and I only have a 5.1 speaker setup and capable receiver so I use the realtek S/PDIF to receiver for audio and mobo HDMI for video
I went into bios and disabled onbard video, allowing the 3450 to take on the role of supplying HDMI audio through its onboard controller, however I left the realtek onboard for the mobo enabled as well... and I end up with the same problem as you bdelariva... the onboard does not want to play nice with the ATI controller... I can not get it to set as default for audio... even with drivers installed.... now if you will excuse me for a few minutes I have to reboot and restore...
