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.

Reboot and then post the contents of the startup log.

The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from any of the Config screens. The startup log will be at the end of System info output.

The log shows a lot of breakage.

Your best bet would be to install the latest 9.0.3 release and if there are still issues then post that startup log. Be sure to read the Setup Guide which contains the required steps needed to prep the image.
