Arghhhhh it's because of a build setting! This was built using OpenAL rather than the windows sound system, so will only work if all the OpenAL dlls are present (no idea how well wine handles it). it is literally for me the change of an underscore in the build directives... wish I had double checked this before the bug fix grace period ended :) - Oh well!
The Game has a few sound queues in there but nothing major... so maybe you can play it with audio disabled on your browser tab, after voting ends I can send a build that will run on your system (fingers crossed)
