Blanket is broken after latest system update

There is a white-noise app called “Blanket” in the community repo. Since the latest Manjaro system update it doesn’t work. And neither does blanket-git from AUR. (But the flatpak version still works.)
It doesn’t display the sound options properly, and it doesn’t play.
This is what I get when I run it in terminal

Try downgrading gstreamer to 1.18.5. See github issue:

That does sound like the right solution, but I don’t seem to have an older version of gstreamer in /var/cache/pacman maybe because my Manjaro installation is relatively fresh.
So I think I will just use the flatpak version of Blanket for now.

If blanket is failing - this is most likely a general issue - and should be reported upstream to to blanket devs.

If you only need white noise you could use SoX

SoX Noise Generation – CloudACM

These examples output noise types for a duration of 1 hour each.
