I have had an R-15PM for a few months now. I love it. Well today I tried to hook them up to my PC via the provided USB cable. And it worked. Windows 10 found it right away and they sounded great. My computed fell asleep and when I started it back up, no speakers in the playback devices. I tried reinstalling USB and Audio drivers. I have tried unplugging/powering down and plugging back in in every possible order. Shutdowns. Restarts. Different computer. All with no sound. Windows 10 sees a "USB Audio Device" but it has a "This device cannot start. (Code 10) STATUS_DEVICE_DATA_ERROR" error on both my main desktop and laptop. Under "Devices and Printers" the Klipsh R-15PM can be seen with a yellow exclamation marker. I also tried the optical in and it works fine. Any help would be great.
