Keyboard volume control used to adjust motherboard audio now adjusts headset

ASUS Z97-E motherboard with Realtek ALC892 audio

The volume control on my keyboard used to adjust the motherboard audio.

After Tumbleweed 20210602 it adjusts the volume of my USB headphone / mic set instead.

While I decide if I like the change (maybe I do) how do I configure what audio device is adjusted by the keyboard volume control?

I figured it out. It’s just a selection choice in KDE.
