aplay device or resource busy with Anker PowerConf S330

[gensyn]

When I first started playing around with the satellite I was using speakers over the audio jack and a USB mic and everything pretty much worked as expected. Now I got an Anker PowerConf S330, which was specifically named by HA to yield great results (not with homeassistant-satellite per se, but still). I can still use the satellite as a voice assistant, but only if I'm not playing audio (e.g. music) at the same time; if I do I get

I don't know why today it's in german, used to be english. But it says that the device could not be opened as the device or resource is busy. So it seems with the PowerConf only one process my play audio on the device while the audio jack has no such limitation. I updated the PowerConf firmware but it made no difference. Does anyone else have this problem or is there something I am missing?

I use the S330 as well and was not aware of this limitation since right now the pi is solely for testing the wake word. I wonder if this will bring issues if media player functionality is added to the satellite.

Other way around for me. I already used the pi as a media_player and now wanted to add the wake word.
