Do you have any details for the time period that you did have sound? Was it a fresh install of Ubuntu 20.04.1? Did you allow internet updates during install? If you still have the ISO you used, I'd also like to confirm the hash of the file. If we can reproduce it, we'll be a lot closer to a solution.
