no playback port & inport set to RtMidiOut about piano-led-visualizer HOT 3 CLOSED

Hello.
Did you disable audio output as described here? https://tutorials-raspberrypi.com/connect-control-raspberry-pi-ws2812-rgb-led-strips/

The audio output must be deactivated. For this we edit the file
sudo nano /etc/modprobe.d/snd-blacklist.conf
Here we add the following line:

blacklist snd_bcm2835
Then the file is saved by pressing CTRL + O and CTRL + X closes the editor.

Hey Onlaj,
Yes I did disable audio output as described, thank you for the quick response! I just double checked and the blacklist is still active.

Edit: I just realized running connectall.rb returns the following error:
undefined local variable or method 'names' for main:Object (NameError)
I'm not sure if this may be the culprit, or what the solution may be.

Update: For anyone having the same issues with flickering lcd, I apparently was running two instances of visualizer.py ontop of eachother (some stupidity with my boot settings) which resulted in the described effect.

I reinstalled everything and that seemed to do it for the rest of the issues.
