No sound in Unity on Linux, but sound works in built game

I found some other ideas on how to fix this by Googling around, but nothing I tried seemed to work. I finally found a log message that seemed helpful: Couldn't open /opt/Unity/Editor/Data/UnityExtensions/Unity/VR/Android/AudioPluginOculusSpatializer.so, error: /opt/Unity/Editor/Data/UnityExtensions/Unity/VR/Android/AudioPluginOculusSpatializer.so: wrong ELF class: ELFCLASS32 That led me down the road of getting 32-bit pulseaudio installed. After I got it installed, I no longer see this error message, but the audio still isn't working in the editor (works fine in the game once I build/run it). I don't see any other error messages in the logs.
