I have a friend who has a 9600GT with dual DVI-out. He has connected DVI to HDMI on his LCD TV.
It all works great... For a while... Then (seemingly randomly), the TV speakers will give a loud scratchy / crackly noise. It's very loud. The TV volume makes no difference, nor does muting the sound. The only solution is to switch to a different input before switching back, or turning the TV on and off.
The interesting thing is that the DVI-to-HDMI cable doesn't include sound.
Could it be possible that the graphics card is outputting something that the TV is interpreting as audio? And if so, why does it only happen randomly and after quite a while.
Sometimes the noise takes quite a while to first occur (after everything has been freshly switched on for a new day's gaming), but once it occurs the first time, it becomes more frequent (but not necessarily progressively with each occurrence). I thought this might be some kind of heat problem?
Has anyone experienced anything like this, or read any article that may be of help?
