Well, I've done some research on this Seems like plugging the headphones in makes pulseaudio change the audio sink port. You can see that by using the
pacmd list | grep "active port" and when you change active port back to "analog-output-speaker" with headphones connected, everything works fine. Give it a try: pacmd set-sink-port 0 analog-output-speaker But I wonder if someone can fix that problem with analog-output- headphones or just automatically change the volume level without changing audio sink port (auto-mute works just fine) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1304074 Title: [X550CC, Realtek ALC270, Black Headphone Out, Left] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1304074/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
