When the Bionic first came out, people noticed a whine when listening to media over the earphones. Motorola was responsive, and corrected it with a later update. But now, with ICS 6.7.246.Xt875, the whine is back. This needs to be addressed---I use my phone primarily for music-listening, and the whine is strong and as annoying as ever.
I would urge anyone reading this post who has a Bionic to test this out---listen for the whine just before a track starts, or just after it finishes. The whine continues during the track/video, and becomes audible when the volume of track/video drops. The only way Motorola will act is if numerous people call them on this.
