PeppyMeter and moOde

[PeterLustig33]

Hello everyone,

After a long time I'm trying to finish a completely new system with PeppyMeter. 
But I can't get the PeppyMeter to run. Here are the facts:

• I am using a Raspi4 with the current ModeAudio version 8.3.9
  
• I have connected a 7 inch display via HDMI. The display works and shows the MoodAudio information. 
  
• I am currently using an external USB Dac with amplifier as a DAC.  
  
• The PeppyAlsa runs without errors
  /home/pi/peppyalsa/src/peppyalsa-client /var/tmp/peppyfifo
  
• The PeppyMeter installation has run without errors.
  
• Starting with (cd /home/pi/PeppyMeter | sudo python3 peppymeter.py) does not work. 
  
  Code:

  pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html
libpng warning: iCCP: known incorrect sRGB profile
  
  
  
• But I don't think that's the problem. 
  
• The display goes black, nothing else happens
  
• The config.txt file returns this result:
  

Code:

[current]
meter = random
random.meter.interval = 20
base.folder =
meter.folder = 800x480
screen.width = 1024
screen.height = 600

volume.max = 100.0
volume.max.in.pipe = 100.0
step = 6
mono.algorithm = average
stereo.algorithm = new
smooth.buffer.size = 4

What can I do?
Can anyone help me?
I've spent a few hours googling since yesterday, but haven't found a suitable solution.


best regards
