Not quite sure whats causing this, but everything i compile for windows standalone is giving me a strange hissing/white noise sound from my speakers that seems to slightly change as i look around the scene with mouselook. Any ideas?
Edit: it seems the brighter the scene the more high pitched the sound is… So total blackness no problem, as soon as something bright comes on screen it starts up
Have you (intentionally) got any audio sources in the scene (ie, are you trying to use audio and it is going wrong, or is the noise coming completely unexpectedly)?
It could be a sheilding or grounding problem in your sound card setup. Do you notice it in windows? Turn your speakers up really loud and slide a scroll bar up and down and see if there’s any sounds. If that’s the case, then what can cause this is interference from your video card getting on the sound card and being amplified to an audible level. If you can move either card to a farther slot from one another it may help.
Sorry to dig up this old topic, but I have encountered the exact same problem:
Now that I just built an exectuable for testing purpose I can hear a high pitched noise/buzzing sound coming from somewhere of the computer. It’s not necessarily the speakers. Maybe the CPU. I work on a notebook with T6400/Ati Radeon 4650 (samsung r522). I never ever had this before - not on any game and it never occurred during PlayMode within the Unity Editor. Just the standalone applications seems to mess it up…
I also tried a complete Empty Project and the same issue…
The high pitched sound starts as soon as the standalone 3D window of Unity opens (not during the resolutionchooser).
I also checked the speakers on high volume there is no “grounding noise” problem.
What the heck is wrong here?! This is completely frustrating!
Edit: ah, others seemed to have the same problem: http://forum.unity3d.com/threads/65923-Strange-noise-coming-from-pc-tower!
Well maybe it’s really because the scene is too less complex?!. I got only some cubes in it with 3 simple color materials. I gonna check this out later, but I hope that’s the real reason. That said, it’s still strange…
I think it’s from vibrations - it’s being rendered at a much faster rate than most games as there is less going on. Throw in a dummy script that slows the game down (lots of unnecessary commands) some complex but invisible objects on the camera.
I get it on my headphones every so often when not playing music while using unity.
