Error retrieving card details

[JJJGGGG]

Hello. I installed this extension as shown, then copied the folder to ~/.local/share/gnome-shell/extensions/. I then opened gnome-tweaks and tried to enable the extension, but an error message showed involving pulseaudio (I didn't catch which error nor I am able to reproduce it). Next I tried opening configurations->devices and i am always presented with an error that says "error retrieving card details, helper script did not return valid card data".

Did you install from master?

[JJJGGGG]

Yes, I installed from main.

[aleho]

There was a bug in master. Pull the latest version please and check again. At least the settings should work again.

If it still doesn't activate I'll be needing at least some gnome-shell logs to analyze it further.

I had a similar (possibly the same) issue. In my case, when I tried to switch outputs, I get an error that says error: Volume Mixer: Querying PulseAudio sound cards failed, disabling extension.

I did a little bit of investigation, and It looks like this is caused by missing Python scripts in the generated zip file; the current Makefile only includes pautils/pa.py in the zip. Once I copy over all the remaining Python scripts, the error went away.

@jdoe0000000 Should be fixed with 3954c4d in main.
