pipewire-pulse[1977]: pulse-server 0x560a49a5df80: [Firefox] UNDERFLOW channel:6 offset:3833856 underrun:16384

If you are filing this issue with a regular release please try master as it might already be fixed.

Version, Distribution, Desktop Environment: Fedora 34 pipewire0.2-libs-0.2.7-5.fc34.x86_64 pipewire-0.3.23-2.fc34.x86_64 kernel-debug-core-5.12.0-0.rc3.170.fc35.x86_64

Description of Problem:

Underflow messages in the journal. There seems to be no manifestation of this elsewhere from the user perspective. So it's purely a cosmetic problem as far as I can tell.

How Reproducible: Often.

Steps to Reproduce:

1. mock webkit2gtk3 building while Firefox is locating on various bbc.com websites, initially not playing any audio when the messages first appear.

Actual Results:

Many messages such as:
