Whenever I plug anything into my laptop's usb ports,and audio jacks any sound coming from my laptop ultimately vanishes. But when I unplug everthing and restart my laptop the sound comes back. When I do plug anything into it, the sound is gone and even though I unplug my mouse and headphones, the sound is still gone. My volume control says there is sound coming out. My drivers are up to date, and nothing is wrong with them. Is it because of faulty ports? I have not had this problem before and only started when I plugged in my mouse as I do every day. This is annoying me because I do play games on my laptop and with the sacrifice of sound for my peripherals, it does get irritating. Please help.Also I am using an Alienware M17r1 and I am running windows vista.
