Android 6 and multi channel audio. What worked for me.

Hi,

TLDR: If you can't get multichannel USB audio working with CrossDJ on Android 6+, editing the /system/etc/audio_policy.conf file might help, if your device is rooted, and you don't care about your warranty.I have been using Mixvibes Cross DJ Android as my portable mini DJ system for a while, and its been great - except the lack of extra output for headphone cue monitoring, without losing stereo. This has limited me to just basic level DJing with it.The new Cross DJ release with Android 6 multi channel audio support promised to fix that for me! So I upgraded my trusty Samsung Galaxy Note 8 tablet from Samsung Android 4.2.2 to Cyanogenmod 13 (Android 6.0.1).

Please help.

I didn't find the right solution from the Internet.
