Cannot stream Arch linux sound to upnp BalenaSound through pa-dlna

[mcurly]

Describe the problem
(As per title) I cannot stream Arch linux sound to upnp BalenaSound through pa-dlna.
To Reproduce

1. Launch 'pa-dlna'
2. Expect to have a new output sink in 'pavucontrol' interface
3. No output sink to the BalenaSound upnp/dlna renderer
4. See error:

Expected behavior
To have a network sink on the BalenaSound upnp (app/service/device) like it has on Android's BubbleUPnP app
Screenshots
(N/a)
Device information

• raspberrypi4 (64bit operating system)

Additional context
I've also tested with moOde upnp and it's working.

Important Note
I've moved on from BalenaOS. I am not sure if I am going to use it in the near future.
From the BubbleUPnP it had good potential, with good sound. But since this is a little difficult to be multiplatform compatible, (and yes, I am aware that pa-dlna is still an 'alpha' project), but I wanted to have it working with not much fuss, something that happened with moOde.

So I apologize if this issue report seems a bit void. Or out of place.

Its purpose is to warn the BalenaSound devs to this.

I hope you understand.

Thank you.
