There seems to be a small problem here. My speakers work fine normally, but I was using Skype, and when they answered the call, it popped up with No Speakers Detected. I then tested my sound using the 7 Volume Control, and it made no sound. I then ended the call on Skype and sound resumed to normal. It's the same problem with my in-built Mic. It also does this on Windows Live Messenger. I don't know what the problem is, but I'd like to fix it asap. If you need it, my laptop is Compaq Presario CQ61-107TU and oh, thank you to everybody who helps out in advance.
