I'm getting a lot of distortion and buzz out of the right speaker on my new n810 WiMax at or near (75%) full volume. It sounds pretty bad much like a blown speaker. If it were audio signal distortion I would expect poor sound from both speakers, but it is only the right side and seems to come and go.

Is this a standard issue with the n810 or should I look into contacting Nokia about the problem?

Have you tried different audio files? Perhaps you are playing a stereo file with bad right signal. Try other files and see if you get better sound.

When the right speaker is acting up, it appears to sound a little better with the higher quality audio (with less compression) but still sounds far worse than the left speaker. I've tried the included .avi videos, mp3's, internet radio, youtube, ringtones, etc. and the buzzing and distortion is there on all of them.

For what it's worth, I have a 13 month old n810. Both speakers started buzzing recently.
