Lately my DDJ-RX has been having some issues. When playing on normal or vinyl mode, my fourth deck only shows one small LED strip instead of the whole thing lighting up, and I'm unable to navigate through the track. This can't be a hardware issue since my other decks (1-3) seem to work just fine.
This video highlights the problem, I've tried multiple USB ports, a clean rekordbox installation and updated the driver and firmware, but no luck with fixing the issue.
Now for the main problem I'm experiencing: audio stutters. My controller mostly plays smoothly but has some serious audio lags/stutters at random intervals. These stutters last for about a second and I can see them in rekordbox as well.
Here is an audio snippet highlighting the problem (Google Drive)
Any input would be appreciated, since these problems have rendered my controller pretty much unuseable at gigs. I'm using the controller with a Dell XPS 13 laptop.
