I haven't been able to get sound out of my computer speakers for quite a while. If I unplug the speakers (Logitech) and just play music off my phone they still work, which makes me think it's my sound card that's the problem. I've tried plugging the speakers into the front and back audio jacks on my tower, but neither will work. If I'm playing music on my computer and open up the mixer I can see that it thinks music is playing, but nothing is coming out. Do I need to get a new sound card? Is there something else that could be the problem?
