I ran into this issue on my Intel NUC and in that instance I think it may be some conflict between the Game Maker engine and Intel's drivers. I'll investigate this and do my best, and any info about your laptop hardware you can share would be helpful. I may wind up pinging the Game Maker people about this one. Sorry for the trouble!
Quick update: this has something to do with the way Game Maker switches to fullscreen mode. The game is currently set to go to fullscreen when it's opened and then potentially flip to windowed depending on the user settings, but if I disable that and the game launches in windowed mode, there's audio. It goes silent as soon as I toggle fullscreen, though. Will continue to work on this and at the very least the next update will let us play on our TVs windowed, hopefully.
Just pushed update 1.0.4 which has a bit of a bandaid on this until I can figure out the root of the issue. If you go into settings, turn off fullscreen mode, and then restart the game, you should be able to play with audio over HDMI. You can manually stretch the game window to your screen size. Sorry it's not ideal, you'll probably still see the window chrome and taskbar, but I'll keep trying to figure out what's going on with Game Maker and these audio drivers. At the very least, I might try to figure out how to do a "windowed fullscreen" mode to circumvent this issue.
