yikes no replies. I'm going to have to add myself as another user having this issue. All of the volume controls work via settings or sound manager app, however media volume continues to get stuck at 'mute'. I'm not sure if this is triggered by the switcher pro app or not. I would have to literally turn off the phone and on to get the media volume audible, then after awhile, it goes back into its mute mode.
Rather odd situation as this started to occur randomly couple weeks ago. Same goes for my 'searching for signal' for my gps...
hmm
