Hello, This is my first post here, I am not a PC expert by any means. Hopefully I won't waste anyones time. I realise this may be a continuation of the thread http://www.msfn.org/board/index.php?showtopic=120963 but as it is over a year since that 'solution' was provided I felt a new thread was appropriate. Needless to say that solution did not work for me. History of my problem: I have just reinstalled Windows XP Professional 2007 (sad story I'll not bore you with) and chose to move to SP3. Thereafter on boot up and after login, the familiar windows login theme starts but stops suddenly half way through. The PC continues to boot and all applications function correctly except for the sound system. No sound whatsoever! All audio drivers show they are functioning correctly in Device Manager. The only odd things I've noticed are: 1 Differing information is presented depending on how you approach it:- Going through - Start/Control Panel/Sounds & Audio Devices/Properties I see "SB Audigy 2 Audio (C8C0)" Going through - My Computer/System Properties/Hardware/Device Manager/Sound, Video and Game Controllers I see "Creative SB Audigy 2 (WDM) PCI Slot 3 (PCI bus 4, device 2, function 0)". I don't know if (C8C0) - (WDM) difference is significant! 2 'Legacy Audio Drivers' Properties has no entry (is blank). I have attached a "Belarc Advisor Current Profile Home PC.pdf" report so that you can see my PC's 'profile'. I hope someone can provide a solution or an insight into where to go next to solve my no sound problem. Thanks Belarc_Advisor_Current_Profile_Home_PC.pdf
