I know 15.04 isn't officially supported but I was hoping someone might be able to help me figure out why this game has no audio. It might be related to my DOSBOX games crashing on start-up as well?

EDIT: I tried re-installing it and it works now so I don't know what happened but it's fixed. Weird.

I had the same problem on Ubuntu 14.04, the game works but no audio.

In my case, it was because I'm on a fairly new x64 Ubuntu install, and I did not have the 32 bit versions of pulseaudio and libasound2 installed. To remedy this on ubuntu: sudo apt-get install libasound2:i386 pulseaudio:i386

Hopefully that will be helpful to anyone else running into this.

Thanks very much!

Thank you! While this worked, I'd like to point out that (at least on 16.04), just running this will cause apt to remove the 64 bit versions of some packages (pulseaudio pulseaudio-module-x11 pulseaudio-utils rtkit). This is after enabling multiarch support with "dpkg --add-architecture i386". On restart, this prevents any and all sound from being played.

However, if you then reinstall the 64 bit packages that were removed, all seems to be well (after another restart). More than the sound just working again, however, I found that the sound that just wasn't coming through from Braid started playing. Thanks for saving me from a silent Braid playthrough!

Just for future readers - you DONT need to install pulseaudio:i386. I had similar sound problem on fresh Ubuntu 16.10 (64bit) and all i needed is libasound2:i386 actually. Installin 32 bit Pulse on 64 bit system is rather risky thing anyway.
