Forgive me if this is simple, I tried searching. I just finished putting my new system together. I have a XFX 5850 and a Asus M4A79XTD EVO motherboard. I have the system running through HDMI to my pioneer reciever and am getting video fine but I cant get any audio. I have installed all drivers and went into my sound devices and the ATI hdmi is listed as the default device. I can't figure out what gives. I know the motherbaord has VIA sound so I dont know if that's causing a problem. My last system had a 4890 and I had sound through that no problem. I feel i must be missin a setting. Any advice? Thanks in advance!
