Hi Siberia.
Thank you answering the question.
In my view this raise the potential issues you could face:
_ a software one ( the drivers)
_ an hardware one ( computer's usb bus).
I would first investigate this side before going further:
I don't remember if you can use an external psu at same time you use usb datastream. If possible then i would try this first* ( isolate potential usb's computer power issue).
If you have possibility to drive the dac through toslink it would isolate the software issue ( from computer's driver side).
If none made an improvement then i would then investigate further within the dac following Jean-Paul discovery and recommandation within his own thread.
* i would take Jean-Paul advice very seriously: if you have parts and knowledge on how to implement a 7905 i would strongly suggest you to do so.
If not then i would search for something similar to the link i gave previously for psu ( and verify there is no voltage peaks as it could damage the chips).
The Protective Earth ( PE) issue Jean-Paul rised could be a very real concern too.

An 7805 that is. 7905 is a negative regulator. Minimum standard, a better regulator can be used.
