Hey all, I'm seeking help to a very strange problem.
I've had my HTPC- Intel i7 860, Asus P7P55D, 8GB DDR3, Crucial 256GB M4, Win7, Radeon HD5770 HDMI -> Onkyo TX-SR707 -> Samsung 720p LCD working perfectly for years, never ever had a problem.
I just bought a Sapphire Radeon HD7850 for summertime gaming because I plan on getting a 55" 1080p LED soon. I installed it a couple nights ago, ran 3D Mark 2011, scored great, then played some YouTube videos because friends were over...
and I discovered that in EVERY video I played, the audio would skip, or cut out/drop out for a second (and the receiver would show no audio signal) and then the sound would come back on just like that. Video is not affected.
At first I thought it might have been the Flash hardware acceleration, so I unchecked that. Still cut out. Then I tried a HTML5 video, still cut out. Then I looped music on iTunes, still cut out for a second, about every 2-5 mins. Then I tried Catalyst 12.3, 12.4, 12.5 beta, and 12.6 beta. Still randomly dropped signal for a second in anything I played.
Then I formatted, still same problem. Then I put my HD5770 back in, and viola, everything played perfectly.
Hmmmm, so it is a faulty 7850??? I then put the 7850 in my office comp (Intel E6600, Gigabyte P35-DSL3, 4GB DDR2), and the audio still skipped in everything I played. I put my HD5770 in this computer, and viola, everything plays fine.
--=So it has to be the 7850 right??? I then connected my 7850 HDMI directly to my Samsung LCD INSTEAD of my Onkyo. NO audio drops at all!!!!!!!=--
So is it my receiver or the 7850? I don't want to get a new 7850 only to discover my Onkyo 707 still has the same issue, and I'm hesitant to get a new receiver (although I want to get one that supports 3D for my soon to be new 1080p TV) only to find out that the new one also exhibits the same problem.
before you pull any hair out i would email ati and the tv company. the receiver shows it 1.3a for hdmi. the newest rev is 1.4 i would see what rev both video card support. I would also pick up a new cables. if your old cables are a few years old they may not be ready for hdmi 1.4. that the new video card may be at.
