Hello, I've bought a brand new DDJ FLX6 recently, and the first time I used it it worked as it should've. The day after, I couldn't hear any audio. Yes, I've already tried changing the audio settings in rekordbox a thousand times, I've set everything as it should be, watched every tutorial about that. But I think that the problem is in the console. I've tried installing Serato and no audio came out with that either. I'm 99% sure my PC isn't the problem because it's one of the latest i7 laptops, with Windows 10 on it. Please help me, I don't know what to do. Thanks.
