Q: when i went on youtube and tried to listen to a song i couldn't hear and (i checked the volume so it's not that) the speakers are plugged in and the lights are green it's just that i can't hear anything coming out from them
A: well you didn't really give any kind of details... but im guessing that your speackers where working before... you asked this question. so im guessing it could be youtube. sometimes people just post videos that dont work right. it could also be that your speackers where unpluged on accident, check for that. and also make sure that its not muted. the volume can be up as high as you want, but if its muted it makes no difference. try using windows media player or just anything that makes sound from your computer. try plugging in headphones and see if maybe it might be your sound card.
