Fallout New Vegas, Honest Hearts: No more sound using wine-1.3

After installing the Honest Hearts DLC for Fallout New Vegas, all of the sudden the in-game sound stops working the second I load a savegame. Running FalloutNV.exe from the console, I get tons of these as soon as the game goes mute:

As a quick workaround, go into your Wine configuration, create a custom application setting for Fallout if you haven’t already, click the Libraries¬†tab and add an override for quartz.

Native then Builtin did the trick for me.
