With loading the Codec_Zero_Playback_only.state via sudo alsactl restore -f Codec_Zero_Playback_only.state my Monospeaker works with this speaker-test -t wav -c 1. With this .state I can't record via the onboard-mic by doing arecord -f cd test.wav.

If I switch to Codec_Zero_OnboardMIC_record_and_SPK_playback.state via sudo alsactl restore -f Codec_Zero_OnboardMIC_record_and_SPK_playback.state I can record via arecord -f cd test.wav, but my monospeaker will not ouput with aplay test.wav. If I switch back to Codec_Zero_Playback_only.state I can play the aplay test.wav and it outputs on my monospeaker.

I assume that the Codec_Zero_OnboardMIC_record_and_SPK_playback.state uses the Stereo OUT, which unfortunatley I don't have hardware at my hand.

How can i configure the .state file to use onboard-mic and mono-out? Is this scenario covered by any .state file here?

The speaker I have has a positive and a negative, but the card does not. I assume the polarity doesn't matter then - will report back if the magic smoke comes out...

Many of the instructions say to sudo things; that does not work these days with alsa and you get the unhelpful message "don't do that." Why sound is set up for multiple users on something so single user as a pi, I have no idea. Could we fix the instructions perhaps raspberrypi people. So far it seems to work by not using sudo if you get that message.

I am running latest raspberry pi os lite version, I have configured the config.txt file accordingly.. however I receive the following error when trying to load the state files:

Any help is appreciated, it seems another user has the same issue: https://forums.raspberrypi.com/viewtopic.php?t=323725

I can't seem to get the codec zero (I have an IQAudio one) working with the raspberry pi 5.
If I take all the steps as instructed here . If I switch the codec + SD card from an RPI5 to an RPI4 everything works.

Another person also has the same issue: https://forums.raspberrypi.com/viewtopic.php?t=365243 with the exact description of actions as me.
