Today I installed a wireless internet adapter in one of the PCI-E slots on my motherboard. Upon starting the PC up and installing the driver the device worked, but when I went to watch a video online I realized my speakers no longer worked. Over the last few hours I have tried rolling back the PC itself, rolling back audio drivers, installing up to date drivers, installing drivers that came on the disc with the motherboard, basically everything I could think of. Also removed the wireless LAN device and rolled back a separate time and it didn't make a difference. I am now out of ideas.
My PC specs are...
Windows 7 64 bit
Asus M5A97 R2.0
AMD FX 6300 Processor
Geforce GTX 660 Graphics Card
Everything worked perfectly before installed the PCI-E device, and I have tested another set of speakers in the PC to see if that was the issue.
Does anyone have any ideas or will I be forced to just buy a sound card to install.
