Geoff_Gale_0_1701 : 25/07/08 01:25 AM : Incident created -   Recently upgraded sound from a Creative Audigy LS to a Turtle Beach Montego DDL. Machine is a dual-boot w/Windows Vista Business. Creative card worked under Mandriva 2008 and Vista. Montego only works under Vista. Hardware Manager reports card is detected and that the proper driver is loaded. Have run through troubleshooting steps listed in the Hardware Configuration Manager, but no joy! Can you suggest another driver or point me in the direction to get this card working? Tnx
