I had a similar problem before with one of sound plugins.Try every plugin for sound. geforce 8600 is good gpu,no matter about m letter.
8600 is the recommended card, and 8600m is quite a lot weaker so its not a good card for pcsx2.
Okay so I've re-downloaded and reinstalled twice now and still no luck. Whenever I look under cddvdrom in the configuration panel I cannot find Linuziso at all!
?
strange
can you post screenshots ?
