Linux Crash on startup: Failed to set default mixer

[Veylon]

I seem to have a unique problem. I try to startup the game in linux and I get this:
Error Util.cpp:57: Failed to set default mixer!

Does anybody know what could be causing this? I had no trouble having the game create a map via the --create flag, so it's not as though it can't find it's files or something. I suspect it's some kind of audio mixer issue, though there's nothing in config.ini mentioning any mixer so I'm not sure what I would have to do to fix it. My sound works fine in other programs.
