I have a set of JBL powered speakers and the input jack fell out. I think that when I plugged it back in, that I accidentally plugged it into the output jack for a couple of seconds. Now I have no sound at all and I need help please. thanks. mtworkowski.@optonline.net

If the input jack fell out, repair it, or replace the sound card.
Although I'm a bit confused about what you are saying, you want to use the output jack on the sound card to connect your speakers to. The INput is for a microphone.
