Nokia Booklet 3g Audio Driver For Mac BETTER
I did not yet check audio, I was too busy with other things. But audio (usually) is not about performance. Either it comes out clear or not (only very few high-end audio cards actually can accelerate anything). You need at least the VoodooHDAudio (or what it was named) driver. The Vaio P did not work properly with it, though. However, it should be possible -if it does not work out of the box on the Booklet- to adapt that open source replacement drivers as needed.
