Have you tried listening to the audio with a headset, rather than with the internal speaker?  Whenever I've had a similar problem with my K1, the headset audio was perfectly clear.  Since the audio to the headset jack and to the speaker comes from the same point, the problem was obviously the speaker.  This was a fairly widely reported problem with Elecraft speakers several years ago.

By adjusting the tension of the speaker mounting screws (so that they are not too tight) the raspy distortion vanished.  As I recall, I also had to flex the speaker magnet mounting frame slightly too.
