Sound Crackling when using Virtual Surround

• PipeWire version (pipewire --version): pipewire Compiled with libpipewire 0.3.64 Linked with libpipewire 0.3.64
• Distribution and distribution version (PRETTY_NAME from /etc/os-release): Fedora Linux 37 (Workstation Edition)
• Desktop Environment: Gnome 43.2
• Kernel version (uname -r): 6.1.5-200.fc37.x86_64

Description of Problem:

Since 0.3.64, virtual surround produces crackling sounds. Downgrading to 0.3.63 or disabling virtual surround fixes the problem. I also tried using commit "1d9640af" from the master branch, but the problem remains.

I don't see any errors in the pipewire, pipewire-pulse, or wireplumber logs
