mellowwwwwwwwww...lol there's three quick things to try:
1. Check Device Manager and make sure there's not yellow exclamation marks or red x's next to anything. And make sure the sound card stuff is listed!
2. Make sure the system isn't muted
3. Make sure the little dial on the right side of the laptop isn't on the lowest setting (that's what got me the first time!)
P.S. nevermind lol. Didn't read the second part of your second post lol
