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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822426 Title: 19.04 Built in Intel HDA sound is disabled upon resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1822426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
