Motorola Droid Razr :: Audio Pop Or Click Before And After Audio Plays?

I've had two Razr's behave the same, whenever audio plays, especially using the headphone jack and external speakers, one can hear an audiable click or pop just before and after the audio plays. This happens with Pandora, Rhapsody, and Google Navigator. I haven't tested other audio based apps yet.Verizon and Motorola say they've not heard of this issue, so I'm wondering how many other Razr owners have noticed this pop? Hearing such noises as the audio turns on and off is not acceptable quality for a Motorola branded phone.I don't know enough about how the Android OS works, but I'm thinking there are two possible causes. First, as different apps access the audio hardware the internal electronics of the phone produce an audible pop as the circuits power up and down. Alternatively, the Android OS may be probing the headpone jack trying to determine if it's connected to external speakers. I've noticed that the pop gets louder as the phone approaches 100% charge.

With a 90% charge or better I've even had the audio output go quiet if the headset cable is moved, even though the audio application shows audio is playing. I know that removing the headset cable will pause the player, but in this case hitting play starts the player and it shows progress, but no audio is heard.
