I've read a few reports here about music not working in Wasteland 2, many without reply. However, those threads that had a reply did not apply to my case. I simply do not hear any music in the main menu, the character creation screen or ingame. All other game sounds, such as voice-over, video music and FX work, This problem only occurs in the Director's Cut version. Also, music plays just fine in the vanilla version.
My output_log.txt says "Setting AudioSettings.speakerMode is deprecated and has been replaced by audio project settings and the AudioSettings.GetConfiguration/AudioSettings.Reset API.". Not sure if this is related.

I'd really prefer to play the DC version. But without music an important atmospheric element is missing. I'm on Windows 10 64 bit using a Steinberg UR22 Audio interface. So far no other game (and I've played a lot) ever gave me problems like this. What might be the reason for this? What could be done to fix this?
