As mentioned by some forum members that this can remain as is, i personally always make sure that just one sound server is running. Is up to you. By reinstalling manjaro-pulse and some of the optional dependencies (depending what you need and want) you will use only puleseaudio server. By reinstalling manjaro-pipewire and again, take a look at the optional dependencies that you might need or want, it will run only the pipewire server. After the install of whatever you decide to use, a reboot of the system is necessary.
This might come handy

From what i gathered, there are quite a few members here with
in their machines and no audio issues. Have you tested a different OS to trim out the possibility that is something hardware related?
