I’m using Ubuntu MATE 18.04 and it doesn’t switch the audio output to my headphones/speakers when I remove my earphones from my laptop’s audio jack. Even when I try to manually switch it in sound settings it doesn’t make any difference.
Puls audio it’s broken. So please make a bug report un launchpad for pulsaudio
Problem fixed. I installed PulseAudio Volume Control from the Software Boutique.
