[PROBLEM] MPD Connection Refused

[refrigerated]

Hi @Tim Curtis ,

I was enjoying my Moode Audio setup for a few days then hit with another issue, initially the on board bluetoth with my Pi Zero 2W causing the audio to be choppy, so i get myself an adapter and all the issue went off. So today, i was listing on my car head unit, and when i reached home, i turn off off the power on my raspberry pi and start again after few hours. Library didn't load.

Logs:

Code:

20250125 215138 worker: --

20250125 215139 worker: MPD service:        started
20250125 215142 worker: MPD port 6600:      connection refused

Turned out, no matter how many time i restart the pi or restart the server, MPD not starting, so i manually start it with no success

Code:

Upon checking the mixer type in /etc/mpd.conf, it's empty:

Code:

audio_output {
type "alsa"
name "ALSA Default"
device "_audioout"
mixer_type ""
dop "no"
stop_dsd_silence "no"
thesycon_dsd_workaround "no"
}

The problem is, i updated the type to software and restart mpd service, all good. But when i restart the pi, it's again set to "". I use bluetooth btw.

i checked the db, indeed is empty:

Code:

moodeutl -q "select * from cfg_mpd"
