When I have both kmix and the default audio volume control applet in the Plasma system tray they both use the exact same icon. I can simply remember that kmix is on the left and volume control on the right, but I'd prefer to change the kmix icon while leaving the volume control icon alone.

By my knowledge the Plasma System Tray is using the plasma theme when showing the KMix & plasma-pa icons

The Audio Volume plasma widget is using icons audio-volume-muted, audio-volume-low, audio-volume-medium and audio-volume-high. The icons can be edited at the /usr/share/plasma/plasmoids/org.kde.plasma.volume/contents/code/icon.js:

function name(volume, muted) {
    // FIXME: hardcoded max value
    var split_base = 65536/3.0;
    var icon = null;
    if ((volume / split_base <= 0) || muted) {
        icon = "audio-volume-muted";

        icon = "audio-volume-low";

        icon = "audio-volume-medium";
    } else {
        icon = "audio-volume-high";
    }
    return icon;
}


i.e.

Changing at here:

Code: Select all

icon = "audio-volume-muted";

to

Code: Select all

icon = "/usr/share/plasma/plasmoids/org.kde.plasma.volume/contents/code/LocalIcons/matt-icons_audio-volume-muted.png";

etc...



Restarting the plasmashell...and the the KMix and the pulse audio plasmoid are using different icons.




Note !

Plasma (plasma-pa) upgrades will overwrite the icon.js.

This was with the Arch Linux & Plasma 5.6.4.
