I have Companion 5 multimedia speaker system and they plug into my computer using USB 2.0. For some reason they've stopped working. I suspect it was a Windows 7 update that made it stopped working, but I've since upgraded to Windows 8.1 and I can't roll back the updates to know for sure.
I use the on board sound my ASUS P8P67-M Pro motherboard. I can see the "2-Bose USB Audio" in my device manager and it' set as my default device. I've uninstalled and reinstalled the latest audio drivers for my board, but I get nothing.
Any suggestions on anything else I can check would be appreciated. The last resort would be to reinstall the OS to see if that fixes it or be lazy and just my old set of speakers and plug it directly into the audio jack.
