I run Win 7 64 bit Home Premium with a Gigabyte GA-P55 USB3 MOBO. As of today,
there is no sound output from the onboard sound device.
Trouble shooting says "device not plugged in", although Device Manager says everything's okay. I've tested the Advent speaker system on another computer and it works fine. I've tested an Altec system on this computer and have the same problem.
I tried a system restore but the software wants me to turn off my antivirus and run it again. Any ideas? Time to buy a sound card and plug it into a PCI slot?

Thanks
