Whenever i try to use the hdmi port for video and audio, i get choppy sounds. What I mean is that there will be sounds for about 2 - 4 secs then silence for 2 - 4 secs then sound again then silence again.
My setup is MSI 890 GXM , 1090T , 4x4 Mushkin Silverline , AX850 , Crucial M4 256 and HD 7970 plugged via hdmi to a Sony Bravia 40" tv.
The problem only showed up after I switched from my HD 6990.
I tried reinstalling drivers, new install of windows 7 ultimate 64 bit, different hdmi cables and different ports.
guys i have registered just to inform for the solution / fix i got.
SOLUTION as for me ( my problem was : bought 7970 dualx. use LED tv and i got no audio with my HDMI cable)
anyways the solution is .. i uninstalled completely catalyst control and all the amd drivers. and then installed catalyst 12.3 . Now everything is working fine for me.
i got my catalyst 12.3 from filehippo . com
