I recently used my earphones to listen to a meditation on my laptop. ever since I pulled out the earphone plug from my computer, I can't seem to get the volume on my laptop to work.I keep getting the visual of the circle with the line through it, basically telling me no sound is available. I've also noticed that when I push the volume button, not only do I get that symbal, there seems to be a red light coming from the plug for the earphone. Very strange. Then I plugged the earphones back in, and I have sound again, and can adjust volume. Anyone have this problem before? And if so, how can I fix this?
