Hello, I've done all the basic troubleshooting, but I can't find the problem. Oddly, the left speaker went out after downloading the audio controller, a Firefox add on. I uninstalled it, but that didn't help.I have Windows XP.I am a novice at this, so your suggestions would be helpful.
It would be good to know, what basic troubleshooting you did, so as not to suggest something you already tried. like making sure individual speaker settings are set correctly, what audio ctlr you downloadedetc.
