I have a SIS 730 Chipset Mainboard socket A running a Duron 700 Mhz CPU. Onboard SIS7018 AC97 Sound System. When system was initially setup everything worked fine but of late for some unknown reason the sound does not play anymore. No problems identifiable in Device manager with drivers loaded correctly (even upgraded latest drivers from the internet to try and fix the problem.
The sound icon is not available on the taskbar so I checked out the Sound and Mutimedia in the Control Panel. Everything in Sound is greyed out and when click on test for Windows sound ie exit program the play button does not activate. Upon checking in Multimedia section it shows "no playback devices available" and is all greyed out.
As i stated before the sound card appears loaded correctly with IRQ ALLOCATED AND NO CONFLICTS, but I can't work out why it is not available in Multimedia.
I have checked the CMOS and it is configured ok and available there and it does show as a Multimedia device on the process of windows booting and plug and plays is identifying it ok.
I have also successfully disabled it through CMOS AND used A pci card which Windows identified ok as plug and play but it too would load ok in Device Manager but not available anywhere else.
Obviously something is blocking the sound card from working and I am now at my wits end in trying to locate the problem. Appreciate any assistance from the wizards in netland
