This sound issue started up for me very briefly but has stopped since I dropped sound quality to low, like was advised with the bicycle bug. I have AM and am patched to 1.55, but don't have Island Paradise.

This is a function that Twallan implemented into MasterController. After clicking on the usual 'Nraas' and 'MasterController', go into 'Settings' and then 'CAS' and you can set both eye and hair colour according to outfit.
