Failed to open ALSA device "_audioout"

[SchroedersKater]

Hi all,

A few days ago I moved to a new location. After connecting my Raspi 3B again I got this error:

MPD error
Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such file or directory

I'm pretty desperate. I searched this forum, but couldn't find a solution.

This the config.txt file:

[cm4]
otg_mode=1

[pi4]
hdmi_force_hotplug:0=1
hdmi_force_hotplug:1=1

[all]
disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
hdmi_force_edid_audio=1
hdmi_force_hotplug=1
hdmi_group=0
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=on
#dtoverlay=disable-wifi
#dtoverlay=disable-bt

I'd be more than happy if someone please could give me hint what to do.
