When trying to start the application after running the automatic script I get the following error:

I have attached a microphone to the pi

I am on a rpi 4b, 128gb sd, latest rpi lite 64 bit

Hi, this sounds like the mlsc is already running in the background or the audio interface has issues.

at the moment we do not support the 64 bit OS. We haven't tested it. Maybe the pyaudio lib has some troubles.

same issue using RPI 4 with 32bit OS

[sameert123]

Hi,

I'm also getting a very similar issue using RPI 4B w Tonor G11 - . Have tried troubleshootinng on my own but no dice. If anyone found a solution or has an update it would be much appreciated!

Thank you!

@sameert123 Can you please try the dev_2.3 branch? The master branch does not have many fixes that are in dev_2.3.

Hey - sorry total newb here how do I switch the branch? I just used the curl automated installation from the setup guide

[Teraskull]

@sameert123 Use this command:

curl -sSL https://raw.githubusercontent.com/TobKra96/music_led_strip_control/master/setup.sh | sudo bash -s -- -b dev_2.3

no clue what this means - any advice?

@sameert123 Looks like some package can't be installed on your pi. What's your Pi OS version?

[sameert123]

It’s the latest 32bit Rpi OS Lite running on a 4B+

[sameert123]

Should I retry w the full OS

[Teraskull]

Try installing a 64bit OS
