Use a virtual microphon as an output device in Element on linux(arch).

[RockeyWereWolf]

Title should describe well what I want to achieve. I created a virtual microphone that I will use in chats and obs as audio input device and as output in Element. I select my main mic as an input device, apply some filters and then want to output this to my virt mic.
My problem is that for some reason Element cannot see Virtual Mic I created(obs and discord can btw). Here is how I created this virt mic:

[rockeywerewolf@rockeywerewolf ~]$ pactl load-module module-null-sink media.class=Audio/Sink sink_name=VirtualMic channel_map=front-left,front-right

Here is what I see in Element's output device selection:

Do you guys have ideas what I did wrong here? Thanks in advance!

I personally am not familiar with PW link with this kind of setup. But from my perspective it looks like an output device hasn't been created and therefore not showing up in Element.

[RockeyWereWolf]

But device is showing up in obs, discord, helvum and even in my audio mixer.

[RockeyWereWolf]

Okay I found a way to set virt mic as an output.
I selected as Default Alsa Output as output of element and then set my virt mic as a default device of system. The issue is that now everything goes through it......
But this proofs that devices are functioning,

[RockeyWereWolf]

Everything works. Element doesnt see device but I found a way to pass output of node created in Element to the virt sink by Helvum,

[mfisher31]

Strange, I don't know why that wouldn't show up then. Element is using JUCE to query the available ALSA devices, so again I'll defer to that being a JUCE bug, or a misuse (somehow) of the API.
