I want to share ioBroker, **Node Red** , rhasspy and **voice2json** on a Raspberry 4 with 4GB with 2021-01-11-raspios-buster-armhf-lite on 16GB SD card. USB-Mic and headphone-jack.

I use kaldi and german.

After I installed at least voice2json, arecord did not work because the mic was already occupied (error 828). The flows for voice2json were not visible.

Before I start from scratch, I would like to ask these questions:

1. Is it possible to share Rhasspy and voice2json with the headphones and USB mic?
2. In what order do the apps need to be installed?
3. What needs to be considered at [asound.conf]
4. Is there also a german forum or a possibility to ask in german?
5. if I install the apps in docker, how can I configure the settings for sound and mic?
6. what is recommended?

thanks in advance
