PRAM, SMC Require Frequent Reset to Ensure Good Sound Quality

My 17-inch, late 2011 2.5GHz Intel Core i7 MacBook Pro with 4GB DDR3 RAM has issues with sound quality. The sound quality isn't horrible, but it improves 10-20% upon resetting the PRAM and SMC. The sound goes from muddy to clear and vibrant after a reset. I am running the latest version of Lion but I intend to upgrade to Mavericks. Also on power-up it can make a noisy sound from the lower right section of the case, I don't know if it's related. After a reset everything sounds great, but after a period of a few days or a week it needs a reflash. I love the 17inch form factor, but I want to make sure this isn't an issue with the Logic Board. Any help is greatly appreciated. Thank You.
