Welcome to the forum!
The way I understood it is that pulseaudio makes the mixing of the different sound signals. And than forwards the signal to alsa, which speaks to the driver, which speaks to hardware. With this understanding it makes no sense to use debian without pulseaudio if you want to use sound. Apparently I am wrong because otherwise it would be installed by default. Could somebody explain it to me?
Pipewire is the default sound server in Gnome at least, and installing PulseAudio can cause conflicts. See:

Some system information would be good - DE, sound servers installed especially. Please post the output of the following (you may need to install package inxi).
Code:
$ inxi -Fxxxrz
