PipeWire segfaults occasionally when multiple applications play sound
Version: pipewire-0.3.42+nightly-211227.fc35 from this COPR repository
Sound device: Behringer UMC-204HD with virtual devices set up to split some channels
Description of issue: PipeWire occasionally segfaults seemingly at random when multiple applications play sound. In the instance this backtrace is from the crash happened while a full-screen game was running and a Discord notification sound played in the background. I have not been able to figure out a consistent repro in the 2-3 weeks this has been happening.
