There is definitely an issue with my MacBook Pro's internal speakers. When shifting the balance control hard to the left there is still sound present at the right speaker. Additionally, the signal on the left speaker sounds as if it is polarity reversed. This is not a source issue. You can confirm this by plugging in a pair of headphone/earphones to the headphone output. You will find the sound to be normal and that the balance control functions as you would expect. This seems to be a design or fabrication flaw. And I find the internal speakers unlistenable. Since my machine is new I am contacting Apple to see if they have a response.
