I'm sorry if this is something simple that I'm just not seeing the answer to but I know next to nothing about computers. I recently hooked up an older computer of mine and the sound has this unbareable echo effect that I can't figure out how to get rid of. I know it's not my speakers because I've tried connecting three different sets.
If anyone can help me, please let me know. The sound is so annoying it makes listening to music, watching movies, or playing games impossible.
