RASPI 4B - cannot get audio-out to work

[wita-sec]

Describe the bug
I have setup a Raspberry Pi 4B Desktop edition.
uname -a tells me:
Linux berry 5.15.84-v8+ #1613 SMP PREEMPT Thu Jan 5 12:03:08 GMT 2023 aarch64 GNU/Linux
I have followed the step-by-step instructions of the Mycroft documents to install MycroftAI.
I can start Mycroft services and the mycroft-cli-client.
Client can process my (over the MIC) spoken uterances.

Problem: I cannot get audio out to work.
The mycroft-cli-client debug window however gives me a valid written answer on my uterance.

I tested MIC and audio out on the system, e.g. with arecord and aplay, this works well.

Log files
Here is an extract from the voice.log which probably shows what happens.
It would be great to get a hint from you whats going wrong in my environment.

Solved: thanks to mycroft audio troubleshooting at https://mycroft-ai.gitbook.io/docs/using-mycroft-ai/troubleshooting/audio-troubleshooting.
Steps:
mycroft-config edit system
updated the aplay command to: "play_wav_cmdline": "aplay -D plughw:2,0 %1",
plughw:2,0 is audio-out of my USB audio card according to "aplay -l"

This is a bit wired, because plughw:2,0 is the pluseaudio default of my system, whereas Picroft uses hw:0,0 as its default.
