[Pkg-utopia-maintainers] Bug#1009663: pipewire: Stream properties `lfe-cutoff` and `upmix` don't work.

[meaneye.rcf at gmail.com]

Sorry for the late reply. Email ended up in spam. Am currently sitting
on 0.3.51 and LFE is still not being generated. I have attached my
~/.config/pipewire/client.conf file in case I am missing something
obvious since no one else seems to be having this issue.
