Crackling noise with external soundcard microphone input

I have a Terratec USB soundcard connected to my RPi4 running bookworm.If I usearecord -f cd -d 5 test.wav I get crackling noises with my microphone.If I specify the device with arecord -f cd -d 5 -D plughw:CARD=HD,DEV=2 test.wav it works well.

arecord -l output:

I tried setting the plughw as default in .asoundrc file

pcm.!default {    type plug    slave {        pcm "plughw:HD,2"    }}

But this file gets deleted every boot.Also changing it in pulseaudio config /etc/pulse/default.pa

load-module module-alsa-source device=plughw:HD,2set-default-source alsa_input.plughw_HD_2

did not make it better.

Any idea?
