Thanks. It looks like the audio driver in the kernel is broken/confused by suspend and resume:

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.
