This Problem just happened since yesterday for me.
Asus Xonar Phoebus, on 10.0.1.40. Problem persists with 4.28 today.
Headphones work just fine in the Speaker output but plugged into the headphone output i can only hear incredible silent noises from the RIGHT channel.
The left one seems to work on its normal volume.
Changing the gain doesnt make any difference to that problem.
To understand this properly: Does the phoebus has seperate amps for each hp channel ?
I wouldnt bother that much if the hp amp just broke completly to have even hp volumes. But this huge difference, you simply cant hear the other ear, makes wearing headphones impossible.
Sadly the has been bought a quite a while ago, 3 years and 3 months, so rma is not an option.
Is there a way to fix this, in any given way ? Maybe does someone know how to break the amp completly to have even volumes on both ears ?
Or according to the link below, is it possible to try flash the firmware ?
edit:
There has been a second, older post about the same problem:

the link from ZL0I above me was helpful for my electronic engineer master friend to look at some schematics of the DAC and OPs and AMPS and ... (the heck i dont know much about that stuff :/)
And hes certain to measure where the faulty parts are and be able to replace it.
