I could reproduce this problem with padme-3 machine.
But it looks like a hardware design limitation, plugging
headset/headphone into the audio jack, the speaker will be muted by
hardware signal (like a enable signal)?
I checked both pulseaudio and alsa driver, there is no obvious problem.
BTW, How does it work under windows?

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.
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
