I workaround it thanks to this: https://bbs.archlinux.org/viewtopic.php?pid=1404929#p1404929 :
``` In "/etc/modprobe.d/intel.conf" put: options snd_hda_intel enable=1,0 This is how you disable or enable specific audio hardware when they share the same driver. If the wrong one gets disabled then replace "1,0" with "0,1" ``` I disabled Nvidia snd_hda_intel and kept my ALC887 from motherboard on, and now suspend works and also I've sound transmitting from my motherboard to speakers. Nvidia HDMI output provides video, but probably not audio :/ It's an issue but right now not too big for me -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1882945 Title: snd_hda_intel blocks/freezes suspend Status in linux package in Ubuntu: Confirmed Bug description: Since some packages upgrade(probalby couple months back; when I had LTS bionic) I'm unable to suspend my PC.
