- The new setup option "DVB/Audio languages" can be used to control which audio
language shall be selected in case a channel broadcasts in different languages

- The "Left" and "Right" keys in the "Audio" menu can be used to switch between
the left and right stereo channels in case there are different audio tracks
in these channels (see MANUAL for details).
Currently there is no visual indicator of the audio channel, yet, and it
doesn't work with the selected audio languages. It also doesn't appear to
work with some DVB cards (esp. the Siemens DVB-S Rev 1.3).

keys can be used to switch between the audio tracks. If your remote control has
a dedicated "Audio" button, the first press of that button brings up the "Audio"
menu, and every further press switches to the next available audio track.
The "Left" and "Right" keys can be used to switch between "mono left", "stereo"
and "mono right" for channels that broadcast different audio tracks in the
left and right stereo channels (as was often done in the old analog days).
The "Ok" key explicitly switches to the selected track (in case the device
for some reason doesn't play it) and closes the "Audio" menu.
The "Audio" menu will automatically disappear after 5 seconds of user inactivity,
or if any key other than the ones described above is pressed.
