S4 has loud buzzing and clicking noise in headphones only

I am wondering if anyone has this problem - in the right cue side only I sometimes have a buzzing sound that occurs when I load a track and press play. Then if I press play again and cue it stops. Also, when the track is playing there is a clicking sound that almost coincides with the beat of the song. Remember - these sounds are only heard in the headphones. The live output heard by the audience is clean. I have tried recalibrating the decks, but it does not fix the problem. Any help would be much appreciated. Thanks!

Check that the tick isn't on. There's a headphone symbol in the advanced section of each deck, there's also a master tick in the clock section.

thank you! It worked. I thought I checked that. Cheers!

Weird, I have the ticking sound in only the A deck when it is cued, its exactly on the beatgrid and the tick button is switched off, and switching it on only amplifies it. Again, only happens in Deck A for the headphone cues. Not the live output. any suggestions??

Check that tick isn't checked in the clock section in traktor.
