Cambridge Audio azur 351a buzzing sound in phones?


hi there is a buzzing sound in the phones input on the right side of the headphone in my Cambridge Audio azur 351a I tried on and off the direct button but the buzz is still there, when I tried it on my Denon DCD-510AE phones input the buzz is gone.
ebfidelity
That is obviously a problem of the headphones output, most of the times built with cheap materials on such units(just a simple add on)
Is buzz consistant and same with volume changes or it gets quiet or louder?
Headphone jack if used frequently, may develop damage in soldered wire connections. Reapplying a new solder may solve issue.
