How to save wireplumber configuration?

Hi all,

I’m currently running pipewire with wireplumber as session manager. So far so good.
Now, when playing audio through spotify this is stereo only, however, on my 5.1 speaker setup I would like to mirror Front-Left to Rear-Left and same for the right channel. I’ve used qpwgraph to achieve this and it looks like this:

This is all working fine now, however, as soon as I close spotify, the audio routing is lost and restored to default. Does anyone have an idea how to save this, so each time I open spotify I get the audio routing back as outlined in the screenshot?

All the best,

I would like to know this as well.

Looks like saving / keeping audio configurations is of no interest to anybody.
As we are living in fast moving times, it looks like something like that is not necessary anymore.
