Raspiaudio OnBoard speaker continues playing with connected headphones

RASPIAUDIO

Hi community,

I am doing my first steps with raspiaudio. I am using DAC Hat Soundcard.
If I am connecting a headphone using audio jack, the raspiaudio soundcard continues to play onboard sound. I would expect the speaker will stop and only headphones play sound.

Probably I configured something wrong, though not sure if this is an hard- or software issue.

I am using GPIO pins for an RFID reader an arcade buttons though, but not using 2,3,18-21.

/etc/asound.conf

pcm.raspiaudio{
        type softvol
        slave.pcm "plughw:0"
        control.name "Master"
        control.card 0
}

pcm.!default {
        type plug
        slave.pcm  "raspiaudio"
}

/boot/config.txt

...
dtoverlay=hifiberry-dac
dtoverlay=vc4-kms-v3d,noaudio
...

I am looking forward for your ideas and hints.
Thank You!

I was able to resolve this desoldering two pins.
