A bang, a gunshot, a "pop of death": Some owners of Sonos' Arc and second-gen Beam soundbars have been dealing with a striking audio disruption with their audio systems since at least December 2020.
The issue now has a fix, and it should already be available to users. Updating a Sonos mobile or desktop app and then checking for system updates should push the changes to Sonos speakers.
