PC Speaker Help

[Azumangaman]

Hey guys,

I recently picked up the Logitech X-240's. The first night I got them I plugged them into my computer and they worked perfectly.
Now, they just don't play any sound.
If I plug my ipod into the speakers they work fine, but it won't play sound from any Youtube videos, music, etc. on my PC.
Its driving me nuts.

Any ideas as to why it stopped working?
Everything is plugged in.

Have you checked the volume level on the PC itself?
Is the sound card or on-board sound (whatever you're using) activated in device manager?
