Please don't respond if you can't read the following details:

My speakers work perfectly. I hooked them up to my iPod to see if they were working properly, and they are! So they aren't broken.

However when they are connected to my PC they do no work at all! And no, they aren't muted either. I've checked all the speaker settings. Everything is dandy.

I have another issue... when I'm on 'deezer.com' or 'youtube', or any site that plays videos for that matter, I can't play anything. On youtube it plays a video for 2 seconds and completely stops. The video is loaded, but it just doesn't play. I can move it to anywhere in the video. Like to 0:35 and it will stop at 0:37

What is going on?! Please help me!
