I'm on Linux Mint 19.3 (Kernel 5.3.0-28) and my mainboard comes with a Realtek ALC887 onboard chip (snd_hda_codec_realtek). Due to the default power managment the power saving state switches on and off on a regular basis, resulting in noticable "click" sounds when the codec gets switched back on to full power. This is pretty annoying, e.g. when visiting websites with an embedded audio element - it makes an audible click every time through the speakers.
How can I disable the power saving permanently?
Or is there a way to fix this popping noise with some sort of option for the snd_hda_codec_realtek module? I remember that I didn't have this noise on Windows at all even at startup. Realtek also advertises the ALC887 with "unique de-pop circuit: Reduces start-up popping noise".
