DJM-750MK2 Firmware v1.05 and still buzz noise on headphone output

Hi,

I just updated my DJM-750MK2 with the latest firmware v1.05, in the hope of solving the infamous "buzz on headphone output". But, up to this moment, nothing has changed.

I would like to know if there is any fix for that or if the engineering team has figured out what is going on in some units.

Seems like some signal is being permanently processed by the DSP and filters, from the moment you turn on the mixer. When you change the filters, there is a change in the noise tone.

Has anyone figured it out?

Thank you
