My pulseaudio misdetects the audio output. It detects Headphones every now and then, eventhough no headphones are plugged in.
Can I ask Pulseaudio to not automatically mute, if Headphones are plugged in? Maybe a manual way to switch?
The laptop has a single sound card, so it switches between Speaker and Headphones.
"KDE's System Settings > Audio Volume > Automatically switch all running streams when a new output becomes available" sounds like the right thing to disable, but it is already disabled.
