Problem setting up Rotary Encoder #2236

Hi!
Has anyone encountered a problem with a rotary encoder? I have tried a lot but can't get it to change my volume. I have a Raspberry 3B+ and the RC522 reader. I connected it to GPIO5 and GPIO6. Then I changed gpio_settings.ini

[VolumeControl]
enabled : True
type : RotaryEncoder
timebase : 0.02
Pin1 : 5
Pin2 : 6
functioncall1 : functionCallVolU
functioncall2 : functionCallVolD

When I run the rotary_encoder.py script I get the output that it is working:

INFO:__main__:RotaryEncoder: Calling functionIncr 1
Function Incr executed with (1,)

I also changed the audio output section in my mpd.conf and restarted the service.

audio_output {
        type            "alsa"
        name            "My USB Soundcard"
        device          "hw:1,0"
        mixer_type      "hardware"
        mixer_device    "hw:1,0"
        mixer_control   "Speaker"
#       mixer_index     "0"             # optional
}

However the web interface says "Undefined" in the field where it normally shows the volume and the rotary encoder doesn't do anything. The MPD log says the following:
exception: Failed to read mixer for 'My USB Soundcard': failed to attach to hw:1,0: No such file or directory
Can anyone give me a hint on this?

Thanks for your feedback! I tried this here I read that it should be Pin1 and 2. I just got it to work: I had to change the mixer type to software - which seems counter intuitive to me, but it works:

audio_output {
        type            "alsa"
        name            "My USB Soundcard"
        device          "hw:1,0"
        mixer_type      "software"
        mixer_device    "hw:1,0"
        mixer_control   "Speaker"
#       mixer_index     "0"             # optional
}

What's the result of tail -n 200 /var/log/syslog?

PinDown: 6

Did you tried with this?

Thanks for your feedback! I tried this here I read that it should be Pin1 and 2. I just got it to work: I had to change the mixer type to software - which seems counter intuitive to me, but it works:

audio_output {
        type            "alsa"
        name            "My USB Soundcard"
        device          "hw:1,0"
        mixer_type      "software"
        mixer_device    "hw:1,0"
        mixer_control   "Speaker"
#       mixer_index     "0"             # optional
}
