Greetings. Summary: After a recent fresh install of Windows XP, the sound on my computer is no longer working. Details: As you can see below my motherboard is a bit old, but still fine for my current purposes. I've been using it for about 6 years with no problems. I recently had to reinstall XP because of a hard drive upgrade. I installed all the drivers that came with the motherboard on CD and also installed all the updates from SOYO's site. At one point during my driver installation the sound WAS working, but at some point it stopped (unfortunately I do not know exactly when). When I try to install the C-Media Driver that is from Soyo's site (listed under the drivers for my specific motherboard) I receive this error: "Our audio chip provides mult-speaker surround and realistic sound effects. Due to the fact that your computer is not equipped with our audio chip, you can not avail yourself of these advanced features. For more information, please contact your computer dealer - C-Media Electronic Inc. I have tried installing the latest drivers from C-Media's site (the CMI8738_WDM_0639XP.zip package), but receive a message during install that says "Waiting for audio driver......" that hangs indefintely until I click on Exit, which then restarts my computer, but still without sound. The PCI Audio Applications software installs successfully on reboot, but when I try to run it I receive: "Can not execute all the components of AudioRack. Please check program files and registry settings or just reinstall AudioRack." There also seems to be an opensource driver available (CMIDriver-1.1.4-bin-x86.zip). However, when I try to install that I receive this error "Driver Installer (CMI 8738/8768) has encountered a problem and needs to close. We are sorry for the inconvenience." (complete with the handy Send Error Report business to Microsoft). Thoughts: It seems to me there is some type of driver conflict going on somewhere but I do not know what else to do or try. There is a more detailed list of my system below. I'm also having random IE7 problems where it freezes and says it has to close and send Microsoft the famous error report, but I believe that my be unrelated (??) However, I am also receiving various BSODs at random times too, not always the same one either. I believe this is probably related. Anyway, if anyone has any ideas on what I could try next I would truly appreciate it. I've spent a good bit of time at this myself but have come up quite dry. I have searched a quite a few forums and FAQs for all the associated software vendors involved but have found nothing there either. If there is any more specific information that is needed about my system, I will be more than happy to post it for you!
