I recently lost sound in the Right internal speaker on my Core Duo MacBook. Sound is still good with headphones. Are there any other known problems that would cause this, before I replace the speaker or check wiring? Thanks Much! Jason

If the sound is good in headphones I would look for a bad speaker, or less likely a wiring problem. Ralph

Could it be this Known Issue? Any strange lights, pops, or new icons if you adjust sound? N.
