I have a relatively new acer laptop and have had no problems with it so far... until today! I was watching a youtube video (with my earphones plugged in) when the sound suddenly went really strange and low and kind of tinny with an echo. I thought it might just be the video so I tried listening to songs on spotify. At first the music sounded fine, but then the singing started and the lyrics were all strange and had an echo as well! So then I thought it might be my earphones, but when I tried them in my iPod there were no problems at all. The speakers on my laptop are fine, it's just when I plug my earphones in that it gets weird again! I've restarted the laptop but the problem's still there, and have looked to see if there are any default sound settings I can change in control panel but I can't find anything. Any help?
