I guess, once the mobile clients stopp working we will see a decline

Second for kiss ... You have to get used to it and understand the concept. I really really like it now.

So, what was it then?

After some more testing, I think this is indeed the case. The problem is that the device has two input channels ("line-in", " external mic"). In alsamixer i can select both as "PCM capture source" (from here) However, the input tab of pavucontrol, i can only select "line in". I switched through all available profiles for the card. But the dropdown only always show "line-in"

Any ideas?

I could do that, the question is what is the correct config file? I think the .state files are more like snapshots wich are applied to the config when i restore it.

I like connect for lemmy

I wish it would work with pacucontrol, but it dies not give me the external mic Option for the inputs. Alsa does. See my parallel comment.

Thank you! Will try this tomorrow <3

Okay, i had to try it today... Unfortunatley, it was set to "PC/Mac" already. I have factory reset the card and tried again. Have you enabled the sbx profile, or do you use direcr sound mode?

Ahh... that was the reason

I still habe this in my project todo list: https://github.com/MiczFlor/RPi-Jukebox-RFID
