On a HP Laptop with Ubuntu 19.04 (dual boot with Windows 10) the internal loud speakers and headphones are working. Unfortunately only after a boot or reboot, but not after waking up the laptop from suspend.
Ubuntu recognizes the audio device after a suspend (listed in lspci) but neither loud-speakers nor headphones work. Volume can be modified but does not change anything. Do you have any idea how to force to re-load them after suspend?
sudo lspci -v
gives:

aplay -l
gives the same output right after a reboot and waking up from suspend:

I tried the commands suggested here under step 1 without success.
My laptop is a 14ma0307ng.

. I will add the model of my machine in the question. The speakers are listed prior to suspend asspeakers - built in audio
