[NEED HELP] No more music online?

It's weird but sicne the latest autobuild i can't get in-game music working when playing online. It works offline just fine. I know that not all maps have music enabled. But it seems like no map has music anymore when playing online. Even the "standardmaps".
Is there an option i don't know of?

Could you confirm the problem by moving a map file out of dlcache/ and test it locally, to see whether the same map file will have music off-line and no music online?
