DDJ-SB2 External soundcard issues

Hi,

I'm using my new DDJ-SB2 as an external soundcard in Windows 10 (64 bit). Traktor and Rekorbox works fine and give clear audio output. Systems sounds are also played normally. When I'm using certain programs however, like Chrome or VLC Media Player, I'm hearing no sound. Both programs also don't show up in the Windows volume mixer. It seems that certain external apps can't have their sounds played through the external soundcard of the DDJ-SB2. Is there anything I can do to fix this problem?

Best regards
