Closed jkulzer closed 3 years ago

jkulzer commented 3 years ago

Desktop (please complete the following information):

Describe the bug Front end works, but panon can't pick up audio. I can see the colored line or the bars if i change the layout, but nothing happens if I play music with pulseaudio selected.

Any error message shown in the console Here is the full log output of the plasmoidviewer

Please try replace 

async with websockets.connect(f"ws://localhost:{server_port}") as websocket:

in /home/johannes/panon/plasmoid/contents/scripts/panon/backend/client.py with 

async with websockets.connect(f"ws://127.0.0.1:{server_port}") as websocket:

Thank you! I also added localhost to /etc/hosts (it wasn't there before) so this error won't happen in other applications (probably forgot to do this during the installation).
