OK. I did the maping to "Pause" of both.

In player-mode it works perfect but in tuner-mode
it shows the telephone, it shows speaker-symbol
but does nothing. You have to push the pause-button
twice. First switches the speaker-symbol away und the
second hit on the pause-button switches it back on and
also cuts the music off, which already should have been done by the mute.

Any Ideas ?
