Public bug reported: I suspect this is a pulseaudio or alsa bug.
Our test team reported this: 1. Prepare Padme-3 machine and Install Ubuntu_20.04 OS . 2. Boot system. 3. Play audio or video file. 4. Open Settings > Sound. 5. Hot attach headset. 6. Notice that headset is selected as output device in sound settings and sound can be heard from headset => EXPECTED 7. While playback, select Internal Speaker as output device => KEYPOINT 9. Notice:SUT havo no sound from Internal Speakers => PROBLEM I was able to confirm this - it seems with the headphones connected that I can't select the system speakers. If I don't have headphones connected I can switch between dock audio and system speakers correctly - so it's just related to the audio jack Thanks Mark ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1896098 Title: Lenovo P1G3 - unable to select system speakers when headset plugged into audio jack Status in pulseaudio package in Ubuntu: New Bug description: I suspect this is a pulseaudio or alsa bug.
