it was the default device. I tried switching it to the speakers but it didn't help.

MediaMonkey WASAPI output File: out_WASAPI.dll

I'm running MediaMonkey version: 4.1.30.1914 (gold)

When I plug in my headphones the output doesn't automatically switch from my speakers to the headset. The listed output device changes in Windows and if I use windows media player it works fine, just not in MediaMonkey.

I'm using a Lenovo ThinkPad running Win10 Pro. The audio app is Realtek.
