I recently experienced a weird behaviour of the sound system on my laptop.

I connect my laptop via HDMI on a TV and choose to use the sound system of the TV in Parameters > Sound. Then I unplug the HDMI cable and I am unable to listen to anything on my computer.

To get the sound back on the laptop I have to connect my laptop the TV again and choose to use the internal sound system. And then only unplug the computer.

Is there a way to switch to the internal sound system without having to perform the previous procedure ?

EDIT : What I tried from kenn's comment :

pactl set-card-profile 1 output:analog-stereo+input:analog-stereo

Which seems to be the root of all the solutions I've been linked too. But unfortunately I still can't play a music or a video in my browser or outside. Note : The sound from the system are working.

  • I stumbled across https://askubuntu.com/a/660457/974073 in the Related section. It has solved my problem. Not sure what to do now with this question which seems to be a duplicate of both the links you provided and the answer given in this comment. – Arthur Jul 10 '19 at 19:47
