I have problems with DDJ SX3 !! master freeze and more..

Volume levels increase and decrease on its own

Headphone cue button suddenly causes one of the songs to restart to the beginning of the song.  Almost acting as if it was a cue point button

Song would restart to the beginning of the song by itself.

Master volume in software this freeze don't move.
