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.
