Describe the bug

I have a Focusrite Scarlett 18i20 3rd Gen that I am using with EasyEffects. I am using the pro-audio PulseAudio profile.

I have set up two loopback devices via PipeWire that link to specific inputs and outputs on the Scarlett 18i20 like this:

    {   name = libpipewire-module-loopback
        args = {
            node.name = "scarlett-18i20-microphone"
            node.description = "Scarlett 18i20 Microphone"
            capture.props = {
                audio.position = [ AUX7 ]
                stream.dont-remix = true
                node.target = "alsa_input.usb-Focusrite_Scarlett_18i20_USB_P96R5DB1509A9B-00.pro-input-0"
                node.passive = true
            }
            playback.props = {
                media.class = "Audio/Source"
                audio.position = [ MONO ]
            }
        }
    }

    {   name = libpipewire-module-loopback
        args = {
            node.name = "scarlett-18i20-playback"
            node.description = "Scarlett 18i20 Playback"
            capture.props = {
                media.class = "Audio/Sink"
                audio.position = [ FL FR ]
            }
            playback.props = {
                audio.position = [ AUX0 AUX1 ]
                node.target = "alsa_input.usb-Focusrite_Scarlett_18i20_USB_P96R5DB1509A9B-00.pro-output-0"
                stream.dont-remix = true
                node.passive = true
            }
        }
    }

This is a screenshot from Helvum that shows the individual nodes and the links before EasyEffects is launched, and the the two virtual devices that should be used by EasyEffects marked by red: image

Now, there are two issues:

  1. Whenever EasyEffects start, the existing links that you see are removed. If I kill EasyEffects then the links return.
  2. Out of the two microphone nodes, EasyEffects selects the one that is linked to the AUX7 port of the Scarlett and links to its monitor

Expected Behavior

  1. Existing links are untouched when EasyEffects is started
  2. EasyEffects connects to the Microphone node that is marked by red on the screenshot

Additional Information

The reason why I set up virtual devices and don't connect to the Scarlett directly is because I want to have a layer of isolation. That way EasyEffects would not have to deal with the Scarlett sometimes being disconnected.

wwmm commented 3 years ago

One of the reasons we have always had some kind of problem with loopback devices(since PulseEffects and Pulseaudio) is that they are implemented by the audio server using the same kind of streams that ordinary players use. The result is that they usually appear in our Players and Recorders tab and we try to handle them like they are an audio player. Can you see in these tabs entries related to your loopback devices? If yes try to blocklist them so EasyEffects do no try to move them to our virtual devices. This should fix the problem.

szszoke commented 3 years ago

Indeed the loopback devices appeared in the Players and Recorders tabs. I added them to the blocklist. I will do some testing and report back.

szszoke commented 3 years ago

Adding the two loopback devices solved the issue of the removed links but no links and effect nodes are not created until I manually change the input/output devices and then change them back to the desired ones.

szszoke commented 3 years ago

Another weird thing is that EasyEffects links up with the wrong input device.

Look at the nodes marked with red on the screenshot: image

I was expecting EasyEffects to link up with capture_MONO from Scarlett 18i20 Microphone instead of monitor_AUX7 from the other node with the same name.

szszoke commented 3 years ago

Actually, adding the virtual loopback devices to the blocklist did not resolve the issue. When I start EasyEffects, the links between input_AUX7, output_AUX0, output_AUX1 and their respective targets is removed.

When I kill EasyEffects the links come back.

szszoke commented 3 years ago

There seem to be some issues reported by EasyEffects about setting up links

no links and effect nodes are not created

In order to save cpu power we only link our filters when our Players/Recorders tab have clients that have effects enabled and are active. So this is something to have in mind when searching for our filters links.

There seem to be some issues reported by EasyEffects about setting up links

Looking at the last logs I see

default.audio.sink, Spa:String:JSON, { "name": "easyeffects_sink" }
default.audio.source, Spa:String:JSON, { "name": "easyeffects_source" }

That is probably the source of the error sie: Input device id is invalid.. By default EasyEffects tries to use your default source and your default sink. But as PipeWire has EasyEffects virtual devices set as default and we can not play to / record from ourselves EasyEffects does not know which device to take and the id stays undefined. Ideally our virtual devices should never be set as default. Most of the times this causes problems. This kind of thing used to happen in Pulseaudio too.

wwmm commented 3 years ago

Try to view the connections through the output of pw-dot. The file it generates can be viewd with xdot. I think its output is a little better for debugging.

szszoke commented 3 years ago

Thanks for the tip. I get the same result though. The links are removed when EasyEffects is started and then they go back as soon as I close EasyEffects.

Here are three files generated via pw-dot at three differnet stages (I renamed them to .txt so that GitHub would let me upload them):

  1. Right after the PW server was restarted: before.txt
  2. After EasyEffects was launched: after.txt
  3. After EasyEffects was killed: after-kill.txt

I did some digging with pw-mon and I found that after EasyEffects are started, I get a few removed: x lines. If I follow up the ids, they point to links. If I follow up the input and output nodes in the links, they point to the virtual loopback ports and the AUXn ports on my Scarlett.

wwmm commented 3 years ago

After EasyEffects was launched: after.txt

I see... That is weird... I wonder how the simple act of loading EasyEffects could be having such consequences. It makes no sense at all... There are two ways to make links in PipeWire. One that is "high level" and relies on PipeWire's session manager and another that is a more manual approach. Filters can not be linked through the media session manager. So for them we are forced to use the manual and harder approach. We only use the session manager when moving audio clients to our virtual devices. That is what the per application switch does.

Based on the above the only way EasyEffects could be breaking those links is when trying to enable effects for each stream. But if they are blocklisted this should not be happening anymore... I wonder if the session manager is automatically moving the loopback streams to our virtual devices and breaking the links in the process. Both PipeWire and Pulseaudio have a feature where they try to move a stream back to the last used device as soon as that device is available again. Maybe that is what is happening. Are you using wireplumber or the buit-in PipeWire media session manager?

szszoke commented 3 years ago

I am using the built-in session manager.

wwmm commented 3 years ago

Ok. Let's look at your last log again

new metadata property: 0, default.configured.audio.sink, Spa:String:JSON, { "name": "easyeffects_sink" }
new metadata property: 0, default.configured.audio.source, Spa:String:JSON, { "name": "easyeffects_source" }
new metadata property: 0, default.audio.sink, Spa:String:JSON, { "name": "scarlett-18i20-playback" }
new metadata property: 0, default.audio.source, Spa:String:JSON, { "name": "scarlett-18i20-microphone" }
(new metadata property: 0, default.video.source, Spa:String:JSON, { "name": "v4l2_input.pci-0000_0f_00.3-usb-0_4.3_1.0" }
new metadata property: 38, target.node, Spa:Id, 4294967295
new metadata property: 41, target.node, Spa:Id, 4294967295

new metadata property: 0, default.audio.source, Spa:String:JSON, { "name": "easyeffects_source" }

When EasyEffects starts PipeWire switches default devices on its own a few times. Is it still doing that? I think that something must be going wrong with the loopback devices links in this process.

szszoke commented 3 years ago

That still happens.

wwmm commented 3 years ago

That still happens.

I have the feeling we will have to take this to PipeWire's developers. The most EasyEffects does is asking PipeWire which are the current default devices so we can use them. We never try to set any device as default. I think that the session manager is destroying the loopback device links at some point when switching them between devices. Once EasyEffects is closed our virtual devices are gone with us and the session manager tries to link the loopback devices again. But this time it has no option other than using your hardware as destination.

wwmm commented 3 years ago

Kill EasyEffects and try to create a virtual device

pw-cli create-node adapter '{ factory.name=support.null-audio-sink node.name=my-sink media.class=Audio/Sink object.linger=true audio.position=[FL FR] }'

You can use pw-cli destroy id to destroy this virtual device. You can find its id in the output of pw-cli list-objects Node. Try also to set it as default to see if this triggers any change in the session manager behavior.

szszoke commented 3 years ago

You are right!

When the virtual sink is created, the existing links are removed and when I destroy the sink, the links return. Looks like this issue is not related to EasyEffects after all.

Thanks for the assistance!

szszoke commented 3 years ago

For those who might encounter this same issue, my solution was to comment out streams-follow-default under with-pulseaudio in my media-session.conf file.

There are additional issues though.

szszoke commented 3 years ago

False alarm. This issue seems to be a lot harder to fix. I cannot get a consistent result. Sometimes everything works as expected, other times the issue comes up again.

wwmm commented 3 years ago

Did you try to contact PipeWire's developers? I think this should be reported to them.
