... aaand back from the dead, 8 months later.. I've been busy recording so i decided not to experiment with the drivers..
Thanks Zenith for your work - I now tried 2.7.6d2, 2.8.1 and 2.8.2d6, and they all seem to get rid of the KP, but unfortunately they also get rid of my onboard sound card...
I'm using an HDTV for my screen and it's connected via HDMI.. Using the updated kexts only allow me to select those digital out, but no HD audio with line in/outs - which is what i need. Mixing through an old LG 37LD450's speakers is far from optimal ;]
I rolled back to my random KP inducing kext, which i can live with since once started it's running fine. Thanks a lot anyway, and glad I could help a little!
