Sound doesn't work in-game?

[shamsia]

So, graphically, the game has been running fine for about the hour and half I played it. I noticed, however, that the sound does not work at all in-game for me. The opening cinematic has sound, but there is no sound anywhere else for some reason. I've checked other games on steam, and the sound is working fine, so i'm not sure why this is really happening. Any advice would be appreciated.

When I was able to play the game yesterday, for what limited time it would work. Sound would periodically switch on and off. I use a realtek audio on-board sound. Isn't the best sound but works out in all other games and media programs. I'm beginning to think major issues of the game are steam related. I'm unable to even launch the game anymore. Wish I could offer more help.
