[SOLVED] Audio doesn't work only if HDMI is plugged in at startup

Hello community,
When I boot my laptop, if the HDMI cable of my external monitor is already plugged in, the audio from the laptop speakers doesn't work. My external monitor has no speakers. If I boot my laptop without the HDMI cable, the audio works and continues to work even if I plug the HDMI cable in later.
I have alsa and pulseaudio. I've already checked that Master and Speakers channels are not muted. In pulseaudio the volume bar moves when I play something from youtube.

This is the result of aplay -l

Likely because a port switch happens based on the availability of the HDMI device. Either comment/remove load-module switch-on-port-available from your /etc/pulse/default.pa or configure your analog profile to be sticky: https://www.freedesktop.org/wiki/Softwa … ettosticky

Should that not suffice post

pacmd list-cards
pacmd list-sinks

during this not working situation.
