Crackling headphone output after waking up from sleep

[jkelol111 [Nam]]

I have performed a fresh install of Ubuntu 18.04.4, Ubuntu 19.10, and Ubuntu 20.04, as well as Fedora 31 and all of them have this issue with this audio codec. On Windows 10, sound plays perfectly when waking from sleep, whereas on Ubuntu there is this strange 'crackling' sound that occurs when some playback is happening. Laptop is the HP Pavilion x360 Convertible 14-ba0xx.

This issue seems very similar but it looks like no one is fixing it: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1648183

(I can confirm Erikas' solution in the above bug thread works, there is no more crackling on resume from suspend)

Do note that audio is flawless right after boot, this only happens if the laptop is placed into suspend and then resumed.

I upgraded to Ubuntu 20.04, issue is persisting.

I have fixed all the issues with this device (HP Pavilion x360 Convertible 14-ba0xx) with the following options:

- /etc/modprobe.d/alsa_base.conf

Add this: `options snd_hda_intel model=alc295-hp-x360` (this fixes the bass speaker not working and the non-functional mute LED on my HP Pavilion X360, even though the fix was meant for the HP Spectre x360)

- Follow this guide: https://wiki.archlinux.org/index.php/ASUS_Zenbook_UX430#Headphones_audio_is_too_low (thanks to Erikas on the older bug)

I think this should be a quirk in the kernel to be automatically applied for the HP Pavilion x360 with the ALC295 codec.
