I just got a MicroTrack II and am wondering if anyone else with this model has the following problem. The right level control and volume control seem to work intermittently. When booting up the device, the right level and headphone controls wither work normally or do not function at all, including not activating the backlight. The only way to correct this is to reboot, sometimes having to do so several times before these controls function again. All the other controls, including the left level control, always work fine. No combination of settings that I've encountered seems to have any effect on this problem.
