I'm having a strange problem with my Tour. The mute button works fine to pause the media player when I'm listening to music. However, when the Tour is in the holster, the mute button doesn't pause the music. It used to work before and I don't remember changing anything. When I use Pandora, the mute button will pause Pandora just fine when in the holster. So the problem seems to only be with the media player. Any ideas?
