I am seeing a serious audio problem in my system on certain pieces of music. It appears to be "crackling" or "static" noise when certain low frequency stretches are played. I have two clips that demonstrate the problem in my car, and I would appreciate if others could take a few moments to download the clips and test this out on your Model S as well. https://soundcloud.com/richard-doherty-4/30hztest https://soundcloud.com/richard-doherty-4/tesla-test-mp3 The first sound is a small segment from a commercial song that is looped many times. [Note: I believe this falls under fair use, as it is a small clip used for testing and criticism. Kudos if you guess the original song.] The second sound is simply a 30Hz test tone. My sound system is the basic model (not the upgraded Sound Stage, nor the super upgraded sound as announced this morning). I would appreciate other owners to test the sounds and see if you hear the distortion. The noise becomes even more evident if you boost the low frequency slider on the EQ in the settings panel. The noise appears on all channels no matter the balance/fader settings. I was trying to figure out if only my car is affected, in which case I'll ship it back to the dealer for fixing. Thanks for your help and participation.
