I am now also reminded of this "feature", which was a patch in 16.04 and seems to be an upstreamed feature in 17.10:
https://git.launchpad.net/~ubuntu-audio- dev/pulseaudio/tree/debian/patches/0100-switch-on-port-available-Switch- from-HDMI-to-analog-.patch?h=ubuntu-xenial Not sure if it's related. That module "switch-on-port-available" is definitely one that Ubuntu uses but is not mentioned in the documentation: https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/ So I'm not yet sure what it's meant to do. ** This bug is no longer a duplicate of bug 1702794 Automatically switch audio devices on connection -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707611 Title: Sound does not automatically play on new audio device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1707611/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
