i want to combine MMM-TouchPlayerBasic and MMM-Podcast, until now without succes

[Ralf]

I have both modules installed. MMM-TouchPlayerBasic and MMM-Podcast.
Everything works perfectly. Now I would like to use MMM podcast via touchscreen without button. I have added a picture and the scriptfile to MMM-TouchPlayerBasic.
the script (ard.sh):

sudo omxplayer --vol -3000 /home/pi/MagicMirror/modules/MMM-Podcast/video.mp4

Then made executable:

chmod +x /home/pi/MagicMirror/modules/MMM-TouchPlayerBasic/scriptfiles/ard.sh

Restart rpi.
When I press the touchbutton nothing happens.
The MMM-TouchPlayerBasic ( each radiostation) himself is still working perfekt,
If I write the same command in the cmd window via ssh the “Tagesschau” video is running, overlapping the MM, with sound, everything perfekt.
Why it does not work in the module?
Maybe it has something to do with the permission rights?
Many thanks already in advance for your help.
