system data shows 2 sound servers running
Sound Server-3: PulseAudio v: 15.0 running: yes
Sound Server-4: PipeWire v: 0.3.33 running: yes
Pipewire might be trying to take control of audio devices from PulseAudio
But Pipewire cannot work unless all PulseAudio packages are replaced with Pipewire dependencies
You can either disable the pipewire systemd socket and service to continue using PulseAudio
systemctl --user mask --now pipewire.socket && systemctl --user stop pipewire.service
Or Install manjaro-pipewire to get the additional dependency files for Pipewire and remove PulseAudio
