I just tried to reproduce this problem, but couldn't. Installed the ubuntu 20.04 daily built image on my Lenovo X1 Carbon 7th sudo apt dist-upgrade reboot and check the pulesaudio version, it is 1:13.99.1-1ubuntu1
Paring a bluetooth headset (Sony WL-1000X), it connected successfully check the gnome-sound-setting: the output device is Headset - WL-1000X the configuration is High Fidelity Playback (A2DP Sink) Click test Front left and Front right, the sound output to my BT headset choose speaker - Cannon point-LP High Definition...(internal speaker), click test front left and front right,the sound output to internal speaker. Disconnect the BT headset plug a usb audio bar (one headphone and one microphone) the output device is automatically changed to USB Speaker - Audio Adapter (Unitek Y-247A) click the test front left and front right, the sound output to usb headphone manually select internal speaker from gnome-control-center, click front left and front right, the sound output to internal speaker. So looks like everything worked as expected. Didn't reproduce the problem. Also added my testing result to pulseaudio/issues/832. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866194 Title: [Dell Inspiron 7370] shows up in the sound output options but the sound keeps being emitted from the internal laptop speaker To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/1866194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
