org.kde.plasma.pulseaudio slows down GTK+ windows startup

For a long time, I've been noticing a problem with myself starting Fifefox, Terminator after turning on the computer.

The window frame opens and you have to wait ~40 seconds for the window body to appear.

I launched

journalctl -f

I noticed that I have to wait for the sound-related processes to start up. Why is this happening? Obviously, early on I did not have this.

I think the topic is linked to my other topic → https://bbs.archlinux.org/viewtopic.php … 9#p2056489

Re: org.kde.plasma.pulseaudio slows down GTK+ windows startup

How are you starting your session? What's your output of 

systemctl --user status pipewire pipewire-pulse wireplumber pulseaudio

Migh also be a red hering and your issue being related to the portal implementations.

Re: org.kde.plasma.pulseaudio slows down GTK+ windows startup

I don't think this and the other topic are related. From this you probably want to install rtkit so that the device priorities don't fail, and by the lack of portals, do you not have any implementations of xdg-desktop-portal/did you intentionally remove those at some point? I'd assume this latter point to be more relevant to the freezing issues you experience here. Output of 

pacman -Qs desktop-portal

?

Re: org.kde.plasma.pulseaudio slows down GTK+ windows startup

Is there a reason that is installed but it's base requirement xdg-desktop-portal isnt't ? does installing xdg-desktop-portal help?

Re: org.kde.plasma.pulseaudio slows down GTK+ windows startup

I installed the package. Now I have:

pacman -Qs desktop-portal                                 
local/xdg-desktop-portal 1.15.0-1
    Desktop integration portals for sandboxed apps
local/xdg-desktop-portal-kde 5.25.5-1 (plasma)
    A backend implementation for xdg-desktop-portal using Qt/KF5

Installed package did not help.

No. I have not uninstalled this package. It simply wasn't there.

Re: org.kde.plasma.pulseaudio slows down GTK+ windows startup

Did you reboot after installing that? or at the very least start them in the user session?

Yes I'm seeing that it's not implicitly included with the implementation from KDE which seems weird. Other than that you can try whether downgrading pipewire-pulse as a stop gap mitigation for this and the other issue helps.

Of course

For example. I have degraded the package

pacaur -Qs pipewire-pulse
local/pipewire-pulse 1:0.3.20-1

And I do not have slowdowns, but now I do not see the ability to switch between audio channels. For example, I can't switch from analog to optical (and vice versa).
