I'm pretty sure this is a Win 7 issue as someone else I've spoken to at work has had pretty much the identical issue as I'm having now.
I had an issue with a USB printer, I kept getting a USB Device Not Recognised error, this was on my main pc, and also 2 different laptops, I was making sure it wasn't just my pc! Eventually after I completely unplugged my printer power, it came back on and the drivers
installed with no problems.
But now this has given me another issue. Straight after that began working fine again, the right channel stopped working. If you turn the speakers up you can just about hear something, but it's so faint. I have checked my balance settings and they're all aligned correctly, so that isn't an issue. I've even reset my bios settings just in case. Nothing seems to work!
Any advice or help is gratefully appreciated!
