Speaker Noise only when PT launches

[Mdubbs818]

Hello all,

First time poster. Running PT 9.06 on OS 10.7.4 (Hackintosh). Finding a consistent issue where my speakers (pair of M Audio BX8s) will start making a low level white noise whenever I launch Pro Tools. If I play audio from any other application (Finder, quicktime, iTunes, etc.), no white noise is present. As soon as I launch Pro Tools, the white noise kicks in and is persistent until I quit the application.

I am running a 3.5mm stereo to XLR cable from the analog port (green) to the speakers. Like I mentioned, all other audio plays fine, it only occurs when I launch Pro Tools (which to me rules out a grounding issue or a problem with the speakers).

Any thoughts on the matter would be appreciated.

Thank you,
