In PulseAudio Volume Control, is I go to Output Devices when port is set to Speakers, my internal laptop speakers do not work.
If I change to Headphones (unplugged) the internal speakers work.
If I plug in headphones, it correctly shows port as Headphones (plugged in) but Speakers is listed as Speakers (unavailable) and the headphones do work.
So it seems like Speakers does not really control my internal speakers.
Currently I have to manually change to Headphones (unplugged) after each reboot in order to get sound working.
Previously my speakers were working but I think I've broken it somehow.
I had run some of the commands from
pulseaudio -k sudo apt-get install alsa-base pulseaudio sudo apt autoremove sudo alsa force-reload
Also my system installed some updates.
Sorry I'm new to Ubuntu / Linux.
I probably should have left things as they were.
