I assumed your TV tuner was working, but if you are not able to use it even with other software then it's clearly not a pipewire bug.
As for now, #1035901 bug is just about an error in the journal.Not being able to bring the TV tuner to work is a separate bug; I yet need to report because it also involves w_scan, channels, and vlc; it's more complex, I need to look into it again.
