Hi, I have an audio problem where I'll turn on my computer and for some reason the speakers don't play anything from the front panel or back panel audio ports, but I can plug in my headset in to the USB front OR back and I can use those to listen to music or whatever task. It's not that much of a problem since I can just reset my computer and the audio appears to play through my speakers again using the audio ports (front/back), but I was just wondering is this a motherboard problem? and if it is, then how come my USB slots don't seem to be affected by this, but the audio ports are? Any help appreciated, thanks in advance.
