Hi guys!
Just got my Nommo Pro almost a month ago.
It was working fine until, out of the blue, the sound stopped working (lights buttons and all was working fine).
Everything was connected nothing had been changed, after resetting (power drain, remove cables and so on) it 4 times, i suspected it was the usb connection (with provided cable). 
Tried bluetooth, no dice (still connects. the pc shows sound, but no audio)
Tried windows troubleshot, found nothing.
Tried normal jack cable, now i had a hissing noise.
Disabled the jack went back to usb, and voliá, i had sound again.
BUT!
Now the control pod freezes when in USB mode, but can still control the volume, though no that high peak volume.

This has driven me mad. i live in Denmark and razer has NO support here.
Razer says my product is out of warrenty when i give them my serial number, but the speekers a barely a moth old.
Insanely frustrating when you pay 830,83euro for a product, and you are completely on your own!!

Thanks in advance.
Prebs.
