This is a really odd problem. A few weeks ago I built a "Hackintosh", which is just a PC that is able to run Mac OS X with very little modification.
Everything works well, but whenever XBMC is running and focused, there's a squeak-like sound constantly coming from my computer. I can't tell exactly where it's coming from, but I've eliminated a few hardware possibilities (see below). It starts immediately when XBMC fully launches and ends as soon as XBMC is closed.
Things that stop the squeaking:
- Opening dashboard
- Opening Expose
- Hitting F11 to expose the desktop.
- XBMC doing a lot of processing (opening a folder with thousands of images)
- Closing XBMC
Hardware-related changes that did not help:
- Changing the video card
- Changing hard drives
- Unplugging every fan in the case except the one on the CPU heatsink.
Running XBMC in Windows (non-emulated) does not reproduce the squeak. Running XBMC in Windows under Parallels does.
Any ideas? I'm stumped on this one. It's very odd and very annoying. So much so that I pretty much can't even stand to use XBMC under OSX, because it's constant noise.
Hardware:
- Motherboard: Gigabyte GA-EX58-UD5
- CPU: Intel Core i7 930 (stock speed, stock heatsink/fan)
- Video: evga 9800 GTX+
- RAM: Corsair 3x2GB 1600 DDR3 (stock speed)
- PSU: OCZ 600w
Edit: Wow. I don't know why, but going to Settings > System and changing "Vertical blank sync" from "Always enabled" to any other option makes it stop. Can anyone tell me why that is?
