NF DAC 192 hissing sound from device

Hi, is it normal to hear hissing sound from inside the device or could it be component failure? Sound starts as soon as power is switched on and stops if device is turned off. Sound is quite quiet but I can hear it about half a meter away.

Hi
I will not say it is normal.. It is probably a power supply(SMPS) inductor ,or a ceramic capcitor that is vibrating.
You should pay attention, but no need to do anything.
