Audio Question

I was hooking up my new speakers today, and I (by accident) connected a 3.5mm audio jack into a 3.5mm out, meaning, the port that is a 3.5mm out, should only be connected to SPEAKERS or anything that will OUTPUT sound, if that makes sense.

However, I inserted a 3.5mm jack that was a SOURCE of sound, not speakers.

I don't think this would really do anything, but, it doesn't hurt to ask. I have no way of finding that kind of answer on google, at least not that I know of.

Generally Ok I would say - I have made similar mistakes a few times over the years, and it hasnt damaged anything yet.
