Thank you for your quick reply!

I don’t know exactly how, but I have sound back! I’m running Lubuntu 20.10 on a very old (Win Vista era) PC. I thought I would give Wine a try and I installed the latest Wine Staging and although it didn’t display any video because the iGPU is so old it’s not supported by Vulkan, it played sounds. So I go back to the native Ubuntu version and suddenly there’s sound. I’m thinking maybe I was missing libs or something. Anyway, thanks. 

P.S. Try to reuse an old Mac and put Ubuntu on it for testing for you can. 

That's great, I'm glad it works now for you! Yeah I should look into the libraries to see if any should be required. Maybe there's a list of libs for all GameMaker games.

For the low sound issue in VirtualBox, run alsamixer and make sure volume is up all the way for the virtual sound card. That could be part of the issue.
