The audio channel list contained two 2 entries. Changing to the second did
not happen - default track kept playing, although the newly chosen channel
was checked when next entering the change audio track menu. Changing back
to the default audio channel did not interrupt the audio stream and did
reselect the first audio track in the menu again.
