UR44 Headphones is mono, only left ear works!

Hello,

Brand new UR44, Windows 7 64bit machine
I cannot hear anything from the right side of my headphones (neither phone1 nor 2). This happens in BAW and normal windows audio output!
Anyone else experiencing this?
All other outputs looks ok, I can hear stereo from both speakers, in both Cubase 8 AI and in common Windows application everything sounds ok, except for the phones.
I will soon check with other headphones, in the meanwhile, I would like to know if someone had the same issue

Thanks

See in dspmix master out, if both R and L are rising
