No sound (Ubuntu 15.04 64-bit, USB headset)

[ForSpareParts]

Have you tried setting the system to output sound through something else? Like regular speakers? Did that work? (To narrow down if sound will work in the game, but perhaps there is a problem with usb sound devices)

In the process of doing this testing, I got it to work over my USB headset. So either this is a heisenbug, or, much more likely, I was doing something phenomenally stupid the first few times.

Thanks for getting back to me so quickly!
