I have never tried to read "music" with a dmm but I would expect the various fq's coming thru at the same time to cause problems for the dmm. (It just wants a simple ac signal)Just about any cheap dmm should be able to work with a constant 60Hz signal, and give you a reading. (if it has a scale that reads single digit volts)</blockquote>
