As described in this AskUbuntu post, basically every time there’s some audio playback, there is a variable delay when the audio starts. It can range from anything like a fraction of a second to a full two seconds.

I noticed this first when playing YouTube videos and then it was excruciatingly obvious and a real problem while editing audio in Audacity.

If it’s any good, I’m using an NVIDIA RTX 3070 and I’m still under X, not Wayland, and using Pulse Audio.

My audio is going to my HDMI connected monitor where my speakers are connected.

This is only happening since I did a fresh install of Kubuntu 24.04 earlier this September.

Update: Added my graphics card model.

    ● wireplumber.service - Multimedia Service Session Manager Loaded: loaded (/usr/lib/systemd/user/wireplumber.service; enabled; preset: enabled) Active: active (running) since Fri 2024-12-06 21:17:10 EST; 2 days ago Yep. Looks like I am!

    It might be under /usr/share/wireplumber/main.lua.d/

    It is!!!

    (You can also create ~/.config/wireplumber/main.lua.d/50-alsa-monitor.lua if you want; this is assuming you didn’t change your XDG directories to not use .config)

    Ok so I will try this first.

        So I tried it and when I rebooted I saw my sound was muted. When I clicked on the volume icon in the system tray it said “No output or input devices found.”
