Strange sound from graphics card

sir_wojciech · June 29, 2005, 17:20:05

When I set my application (using LWJGL 0.97) into fullscreen mode, a strange constant sound comes from graphics card (X800XL) like a silent and long beep. The sound is different, when the resolution is changed. :shock:

err - you might want to RMA that card... - no one has *ever* complained about such a thing :shock:

Or maybe it's my program, because it happens ONLY when i run it with LWJGL. Strange....

It could be that your program is running the graphic card's processing up, making its fan spin faster to cool it down (it doesn't need to be a graphically intensive engine to do that necessarily). You might want to run some more experiments.

Also, are you sure the sound is coming from the graphics card? Could it be your monitor? Or your sound card?

It can't be the monitor, but it can be the sounds card who now all of this is strange. Never had such problem even with the earlier versions of LWJGL.

Are you using lwjgl for your sound?

sir_wojciech · June 29, 2005, 20:35:38

No not yet. But I will!

elias4444 · June 29, 2005, 20:37:36

I was just wondering if you had initialized openAL in some way that was causing the sound. Could you try to track down exactly where the sound is coming from?

sir_wojciech · June 29, 2005, 20:40:59

ok! wait a second!

sir_wojciech · June 29, 2005, 20:45:22

Yes it's the graphics card!

sir_wojciech · June 29, 2005, 20:55:45

Ok so now I checked other LWJGL programs and it can be only LWJGL (0.97) or my graphics card!

sir_wojciech · June 30, 2005, 16:18:40

Ok so I did some tests and on LWJGL 0.97, 0.96, 0.95, 0.94 I hear the sound.
When other application (non LWJGL) run in fullscreen mode there's no sound. When JOGL application runs in fullscreen mode there's no sound. So.... I'm sorry to say, but it's the fault of LWJGL.

sir_wojciech · June 30, 2005, 16:20:55

BTW. My graphics card is X800Xl 256 and processor AMD64 3000+ and I use windows XP 64-bit Professional

Did you try Doom 3 with high settings? That is another application using OpenGL that should stress your videocard. It just has to be the fan on the videocard that is making the noise.

Maybe it's because LWJGL is for Win32 and not for Win64?
