HDMI and sound question

[borich_planner]

I have the Asus HD 6450 1 gig silent graphics card and the Asus PB5 Delux motherboard. Will this setup allow HDMI on the graphics card to carry all audio into my Onkyo 706 amp (including HD Sounds).

It will indeed,all Radeon 5xxx and 6xxx cards do audio over HDMI
