Rotary doesn't work with Volumio 2.246

[nullgat]

Looking at jb-rotary.py I think the issue is that volumio recently changed the internal names of the justboom cards.

[shawaj]

Is it just the rotary encoder script that doesn't work?

[francesco-vannini]

Yes @nullgat see this volumio/Volumio2#1307 too. I'll check what happened although the script should have handled the new name too. If you have it handy what does aplay -l return with?

[francesco-vannini]

aplay -l outputs

AFAICT the script should still be working. What's the error you get?

[francesco-vannini]

@nullgat could you also provide the output of sudo systemctl status jb-rotary.service

[nullgat]

fixed config.txt and got the aplay output to look identical, but still receive this

Looks like you do not have the package python-alsaaudio installed.
Try to install it: 'sudo apt-get install python-alsaaudio' and see if you get a bit further.

[nullgat]

Solved, I had to manually install some dependencies, python, alsaaudio, and RPI.GPIO. Not sure why these weren't already on my pi, or not being fixed by the install script?

[shawaj]

I guess Volumio just don't have that stuff installed by default to keep it lightweight

[francesco-vannini]

@nullgat the install already takes care of installing those two libraries so I am not really sure what happened with your particular installation. Glad you fixed things in the end.

[shawaj]

@francesco-vannini will ALSA itself already be installed on all systems? Not just the python add on?

[francesco-vannini]

Indeed the problem for this issue was the lack of -y in the install script. We'll fix that
