When I updated to 10.6.2 everything worked fine except I could only boot the Macintosh partition directly - Chameleon 2.0 RC 3 seemed to be broken, when booting using a separate /Volumes/Boot partition on my S10 hard disk.
Swapping the patched kernel quoted above with the 10.6.2 kernel fixes the multi-boot issue with Chameleon but disables any sound capability (can't select it in System Prefs -> Sound and the speaker icon in the Apple Menu bar is greyed out).
I've tried using versions of VoodooHDA from everywhere I can think, including from inside vaniii's S10 Enabler 1.1.8, the VoodooHDA forum, the 'New audio driver with WORKING MIC' forum topic here (viewtopic.php?f=15&t=3249
), and other versions I had collected over time. None of these re-enable the sound. I've reinstalled SL and re-updated to 10.6.2, always using the S10 Enabler 1.1.8 which works perfectly in every other respect.
Any ideas? Have I a broken driver or a broken methodology? This has been a busy but unfruitful couple of days puzzling this one over
