macbook sound controls grey out and stuck on mute

Hey, My macbook has been having real issues with sound. If i had my headphones plugged in then it would work for a bit then, it would either completely mute my laptop (including built in speakers) or it would continuesly swap between headphones and interior speakers. Ironically i'm a sound engineer and i need it for my work 🙂 Here is some info on my laptop.

Firstly there is NO RED LIGHT in my jack port.

my laptop was originally on snow leapard but i upgraded it to lion (don't know if relevent)

I recently upgraded to Mountain Lion on my MacBook. Yesterday my sound was OK at my favorite coffee shop. When I got home, my computer was stuck on mute. No red light. iTunes would not move. YouTube would work for 11 seconds. Today I returned to the coffee shop and my sound was fine. When I got home, same problem, stuck on mute. I went to System Preferences > Network > Advanced... > Wi-Fi and I deleted the coffee shop network from my list. I restarted my computer, and now everything works fine again.
