some sort of ground loop?
best, marc
That actually does sound like a groundloop problem, are you using balanced cables from the Snow? Balanced cables or low-z both send audio 90 degrees out of phase of each other so they can cancel out ac hum. The other thing you might want to do is get a power conditioner. They aren't that expensive and they can save a lot of valuable equipment.
I just wanted to revive this thread a bit as I'm getting the same sort of sound from my Snow. None of my other instruments have this issue. I've got my whole set up hooked up to pretty clean power from a good UPS.
[edit] I found that if I remove the USB it goes away. 
I've actually got the USB audio working well if I go direct into the back of my PC (for some reason the front ports don't work well which is why I abandoned USB audio) Still, I think it should work fine both ways... no?
Yes I'm having similar problems. Virus ti2 rack running USB mode in Logic x and also Ableton 9 on my macbook pro. Really loud buzzing sound (not ground loop) maxing out the instrument track in both DAWS. It's only just started happening in the last few days.
No buzzing coming from the physical outputs of the virus.
I re-installed the software and firmware.... still same problem.
Tried it on my iMac 2007 and its working fine.
Maybe it's a USB power issue?
Help!!! need to get back to work asap
Same problem here!! some hinote fuzz on the background if usb is connected. HELP!!
Exactly what kind of cables and audio interfaces do you use?
Ok sorry for not being specific.
I actually own an RME Fireface UC + VIRUS TI SNOW and 2 jack to jack cables.
What i still cant understand is what kind of cable im suppost to use exactly? When i read about balanced cables i see only XRL(Canon) types and no JACK ones(the virus TI out and RME input are JACK).
I bought a pair of those guitar cables bu im not shure if those are balanced ones.
What would be a JACK balanced cables? does it need to have 3 ring conductors on each plug to be balanced?
Thanks alot!
I have the same noise Problem with my Snow
I think we need to use a gold plated usb cable
I've tried to change the usb cable with another one (the one from the Novation LaunchControl) and now the noise has almost disappeared
So the Problem is the USB cable.
If someone has gold plated USB cable like this one: [Blockierte Grafik: http://ecx.images-amazon.com/images/I/41lDVATeVGL._SY300_.jpg]
Test it and let us know.
Right!
The usbcable is definetively causing the hum when the the analog outs are plugged in the soundcard.
Groundproblem right?
Anyone?
what you want is no so much a golden connector but decent shielding. ferrite cores help.

Honestly, i really dont get why then access would provide me a default usb cable together with the virus pack wich is not properly shielded to use with the virus analog outs...

because that works for 99% of our users including ourselves. the variable here is not the virus, it is your computer. can be a "noisy" power supply, can be a grounding problem etc.

Please don't try to put the blame on anything but the Virus. At the moment I have a ferrite core usb cable, the power comes from a socket that is not connected to any other equipment and I'm trying two different computers and the noise is still there. What equipment do you want me to spend my money on next to get this working normally? Also, care to explain where did you get this "99%" number? Here are just a few topics just on this board addressing the same exact issue:

grounding issues are something totally common when you connect audio equipment and an unproven 99% have solved those. and the arrival of USB certainly hasn't made that easier. please contact support by email, i'm sure they'll have some tips on how to deal with grounding issues at hand.

Having the same issue. It comes and goes. Re-installing the firmware makes it go away for me... until it comes back. I doubt it's grounding. Never had a grounding issue. The Snows are getting up in years. Maybe some components are failing.
