Using Tumbleweed, KDE (Plasma 5), and kernel 4.4.0-8.g9f68b90-default from OBS
Kernel:stable.

Hardware is a Gigabyte P17 v3 laptop.

I have an amplifier connected to the 3.5mm audio output jack. When it's plugged
in, the sound output is sent through this jack, and not the internal speakers.

However, after a very recent update of all the Tumbleweed packages, if I now
suspend the laptop and then resume, sound will output through the internal
speakers even though the amp is still connected.

If I unplug the amp and plug it back in again, normal behaviour is restored.

Reproducible: Always
