Fixed by changing the value inside /sys/module/snd_hda_intel/parameters/power_save to 0.
This solution only works until you reboot your system.
For a permanent fix, create a new .conf file :
/etc/modprobe.d/audio_disable_powersave.conf
Add the following settings in the file :
options snd_hda_intel power_save=0
Then reboot your system.

How do I revert to the previous behaviour, i.e. prevent the hum?
