Using EasyEffects together with pw-link #1288

I'm using EasyEffects for the noise reduction plugin on my mic and it works very well but I recently tried to use pw-link in order to link together 2 virtual sinks I'm using for recording in OBS.

Here's a screenshot to better show what I'm trying to achieve:

I'm trying to link Virtual Sink 1 (system sounds) and 2 (voice chat) to my speaker so I can hear my voice chat and my system sounds but also keep them split in OBS.

The command I'm using to create the links marked in red in the image above:

pw-link Virtual-Sink-2:monitor_FL alsa_output.usb-S.M.S.L_Audio_SMSL_M-3_Desktop_DAC-00.analog-stereo:playback_FL

Without EasyEffects running this works fine but as soon as EasyEffects starts those links get removed. Using Helvum to do these links works, they will stay intact even with EasyEffects running. But of course with Helvum there currently is no way to do this on system startup and I don't really want to do these connections manually on each start.

Is there a way to solve this conflict or automate the links in another way?

Not an answer to the question, but this sounds like something worth reporting to Helvum, if it isn't already.

There's already a feature request for it here: https://gitlab.freedesktop.org/ryuukyu/helvum/-/issues/34

If some of these links are created like audio streams you will need to add them to our blocklist. Otherwise EasyEffects will think they are an audio player and will try to move them to its virtual device. It may be working with Helvum because it is linking using the same way we link our filters. Without creating audio streams.

What would be the correct way to find out the name I need to add the links to the blocklist?

If I enable the global bypass in EasyEffects the links will also stay intact but I can't see it in the EasyEffects player list.
As soon as I disable the global bypass the links get removed again.

If EasyEffects is the one moving these streams they should be visible in our Players or Recorders tab. The corresponding entries in these tabs will have a button to add them to the blocklist. But there are some unusual situations where PipeWire decides to automatically move streams to our virtual devices as soon as our devices are loaded. That may happen because like Pulseaudio PipeWire tries to restore a stream to its last used device.

Unfortunately the links are neither visible in Players nor in Recorders, so I can't add them to the blocklist through that.

But there are some unusual situations where PipeWire decides to automatically move streams to our virtual devices as soon as our devices are loaded.

Would this move the streams or can it also lead to them being removed? The streams are gone immediately after creating them, if EasyEffects is active. They flash up very shortly in Helvum.

Just tried to create different links with pw-link and it seems like all of them get removed by EasyEffects/Pipewire. Even when creating links to a different audio output, which is not the default device or from application to audio output.

That is weird. If they are not visible in our window then EasyEffects is not the one breaking the links. Kill easyeffects easyeffects -q and restart it in debug mode G_MESSAGES_DEBUG=easyeffects easyeffects. Maybe something in the logs will show us what is going on.

This is the debug log from start to making the link.
