Tried different computer and tried using bluetooth connection same result, its just a brief hiss though.Can you please try different USB port on your computer or even different computer?
Do you hear same when used as Bluetooth receiver?
BTW this problem happened if i connecting up4 to my active speaker using aux cable but when i plug my iem to the DAC there is no issue, although still there is a brief hiss but its so soft nearly inaudible.
If possible i want to asked for the future update to make jack 3.5 port also work as line out too? i think the hiss problem bcause of double amping
