I just tried all 3 options (running Xfce on Manjaro) and here are the results:
Hibernate (saves to HDD/SSD): FAIL - sound stops working upon resume
Suspend (saves to RAM): PASS - sound continues to work upon resume
Hybrid Sleep (saves to HDD/SSD and RAM): PASS - sound continues to work upon resume

My hypothesis is that Hybrid Sleep works because I didn't shut down the laptop long enough to drain the battery power in full, thus the resume works via RAM instead of HDD/SSD.

My conclusion is that there is a new bug where the sound stops working upon resume from HDD/SSD.
