Once again, many thanks to all who weighed in. It appears you all came to the same conclusion I did, that this is a hardware problem with the speaker or the speaker connection. I have recommended to my friend that he seek a replacement if the internal speakers are important to him, or just plug some computer powered speakers into the earphone jack.
