[LAU] clicks in sound when running dual core

[Robert Jonsson]

Hi Chris,

Yes, I do recall the debacle. But, as you say, that should have been worked
around a long time ago already.

It would be interesting to know if anyone else has noticed anything similar?

For the moment I'm content running just one of the cores.. ;)
