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

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) ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 5.3.0-46.38-generic 5.3.18 Uname: Linux 5.3.0-46-generic x86_64 ApportVersion: 2.20.11-0ubuntu8.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jkelol111 1825 F.... pulseaudio /dev/snd/pcmC0D0p: jkelol111 1825 F...m pulseaudio CurrentDesktop: ubuntu:GNOME Date: Tue Apr 21 19:17:10 2020 InstallationDate: Installed on 2020-04-21 (0 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" - Release amd64 (20191017) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:PCH failed Symptom_Card: Built-in Audio - HDA Intel PCH Symptom_Jack: Black Headphone Out, Left Symptom_PulseAudioLog: Apr 21 09:32:13 BrokenHingeLaptop dbus-daemon[1006]: [system] Activating via systemd: service name='org.freedesktop.RealtimeKit1' unit='rtkit-daemon.service' requested by ':1.34' (uid=124 pid=1196 comm="/usr/bin/pulseaudio --daemonize=no " label="unconfined") Apr 21 09:32:28 BrokenHingeLaptop systemd[1165]: pulseaudio.service: Succeeded.
