Raspberry PI 4 Iqaudio Digiamp+ Libreelec Kodi Audio output muting frequently

Hi, Audio Output is muting frequently after connecting Iqaudio Digiamp+ Hat. Please help me to resolve this problem.

1. I am using Raspery Pi 4

2. OS I tried both LibreELEC-RPi4.arm-10.0.2.img.gz and LibreELEC-RPi4.arm-9.2.8.img.gz

3. In the Config.txt I tried dtoverlay=iqaudio-dacplus,unmute_amp and dtoverlay=iqaudio-dacplus,auto_mute_amp

4. There is no line like this in my config.txt dtparam=audio=ON

Please find enclosed the configuration file and the Video .

As is obvious from the video, there is no continuity in the output signal.
