XDJ-XZ Firmware Update Resulted in Sound Problems

Hello,

I just updated my XZ firmware to 1.23 and now whenever I use it in computer connected mode (not in USB mode), suddenly the sound is gone like in 5 minutes. I always need to restart rekordbox and then the sound comes but goes again in a couple of minutes. Never experienced this before the firmware update. Please help.

Thank you,

Tuba
