I recently played Cloning Clyde on my steamdeck and the audio worked, so I made a report on protondb. Previously I had the same issue that there was no audio. Did you try on proton 8.04 yet? Maybe someone can consider marking the game as playable now. But the game still showed steamdeck icons when using a DualSense controller.
