Good details here, that's the kind of info you want to put in the first post, helps with figuring out what is going on.
You may be having an issue with the motherboard, but if this issue only happens once in a while, I'd let it be. To replace a motherboard on a laptop is close to the price of a whole new system. The audio should not have a cable to get loose, unless the jacks are pulling off the system board. However is the chips overheat, they can have unpredictable results.
You may want to make sure your vents and fans are clean (compressed air should do it).
