White Noise on Playback PT8HD

[roderickelms]

I'm running PT8HD on a MacPro under Snow Leopard (yes, I know, but the system works well and comes without a subscription!)

Recently, I've started getting loud white noise when playing back some files. I've tried 'Save Copy In' (including files) onto other drives – still running PT from the same drive.

On a couple of these drives the white noise continues when playing the new file. On a couple of others, they play perfectly.

I'm not aware of any permissions issues and have run Repair Permissions.

I wondered whether this rings any bells with anyone.

Thanks.
