According to the log, when problem happens, the Nvidia hdmi codec doesn't response the HDA controller, Usually it is nvidia graphic driver's issue.
Let us disable the nvidia hdmi audio temporarily and see if this problem still exists? edit /proc/modprobe.d/alsa-base.conf and add "options snd-hda-intel enable=1,0", then reboot and check if there is only hda built-in audio, if yes, please go ahead to do the test. thx. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1822426 Title: 19.04 Built in Intel HDA sound is disabled upon resume Status in linux package in Ubuntu: Incomplete Status in pulseaudio package in Ubuntu: New Bug description: With 19.04, Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller intermittently is not enabled when resuming from sleep. The HDMI sound device is enabled but that is not hooked up on my system. New with 19.04, when sound works after resume, an icon labeled "Built in Audio Stereo" appears during the resume process. Unsure if this is related, but sound seems to sleep when not in use. Launching sound enabled apps produces a quiet "tick, thud" sound as sound system turns on. When sound is not working, killall pusleaudio "fixes" the issue.
