Since I upgraded to ubuntu 20.04, I have a pulsing noise most likely due to a capacitor discharge in my speaker, and I have been able to solve the problem by changing the sound card power_save parameter to 0 by using the line

echo "0" | sudo tee /sys/module/snd_hda_intel/parameters/power_save

found on the site https://www.linuxquestions.org/questions/ubuntu-63/weird-static-noise-in-headset-on-ubuntu-20-04-a-4175681180/. But each time I boot, I have to do the manipulation again. How could I turn this parameter to 0 by default ?

I had the same issue.

Make a file in the /etc/modprobe.d directory, named: audio_disable_powersave.conf

Put this line in it: options snd_hda_intel power_save=0

save/exit and reboot.

A workaround, but it'll do until this is addressed.
