  1. Thank you very much, that version works like it should. Best regards Henning
  2. Hello, I tried the AnalogOut_Play.py example both on my Win10 PC running Waveforms 3.16.3 as well as directly on the Analog Discovery Pro's Linux shell using libdwf.so 3.16.3. I had all the required deb packages (scipy etc.) installed beforehand. In both cases I used the identical python script and audio.wav file. The audio.wav uses double precision float and contains a 3 second linear sweep from 5 Hz to 12kHz (attached to this post). I captured Channel 1's output with an oscilloscope. You can find the screenshots attached as well. The ADP is connected to the Windows PC via Ethernet. I logged into the Linux shell over SSH using PuTTY. While the Python script running on the PC (Python 3.8) produces the expected output, the script running on the ADP itself causes a clipped signal containing only the positive half waves. Please see attached screenshots. Updating the libdwf to 3.18.1 brought no improvement. The signal is still clipped (see attached screenshot). I'm really looking forward to this issue being addressed. Thank you. best regards Henning audio.wav
