I have the problem, that when I plug in a headphone jack, while sound does start on the headphones it still continues through the laptop speakers. When I check in the sound settings, it only shows one output device.
When I connect my headphones via Bluetooth, the sound switches automatically to the new output device.
I am still new to this OS so apologies if this a stupid question.
Ohh and there is only one audio jack on the laptop. So I don't think that is the problem. (I did build a PC before and wondered why the screen was not working only to realise after two hours of troubleshooting that I plugged it in the motherboard and not the GPU xD)
