On Ubuntu 20.04 I experience similar issue as diagnosed by @prayerholmes . Selecting on the pop-up headset breaks the audio (but the microphone works!). After changing on settings->audio the input from `headset microphone - built-in audio` to `Internal microphone - built-in audio` and then back to `headset microphone - built-in audio` it works ok.
My computer is a Dell XPS 9550. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1873384 Title: Headphone has no sound out Status in linux package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Computer: Dell inspiron 15 5577 Gaming intel i5 7300HQ version System: Kubuntu 20.04 Bug: Plug-in headphone has no sound out, meanwhile computer's speaker is okay when unplugged the headphone.
