Topic: Random FF400 pops/clicks on Macbook

Hello everyone,
I'm experiencing random pops using my Fireface 400 on a Macbook white (core 2 Duo 2 ghz 3 Gb Ram)

those pops appear a few times a day regardless that I'm streaming audio or not, you just hear a loud 'pop' through the speaker.

I'm also noticing clicks with Logic and Live but I'll have to check more in details to see if that one is a software issue.

I'm on Tiger 10.4.11

Rme driver 2.62a / unit 1.69

Any advice?

thanks in advance
