Hi,
I also have the exact same problem. Just installed my new HDSPe AIO the day before yesterday. I also hear quite loud computer noises (mouse movements, screens loading, etc.).
Tried both the RCA outputs and the phones jack output - the noise is the same on both outputs.
Now, interestingly, in my case the level of the noise does NOT depend on the mixer - it stays the same regardless of the volume on the mixer (or the output level settings). So, due to the fact that I use a headphone amp, I was able to get rid of the noise in the headphones by increasing the output to quite ridiculous levels on the mixer and then turning up the phones amp volume just a tiny notch (so that the incoming noise is far too quiet relative to the signal to be audible).
However, I can't get rid of the noise in my monitors, because my monitors do not have their own volume control. And the noise is quite audible when working in Cubase, for example, especially in the quieter parts of the tracks.
Elsewhere on these forums I've noticed that certain Gigabyte motherboards were listed among the suspects for some other cards. I'm not sure if this is really the case, but I do have a Gigabyte GA-X48-DQ6.
My PSU is a 750W Chieftec (CFT-750-14C) (http://www.hardware.info/productdb/bGRk … rbo_750W/#)
Is it possible that the noise could go away by using the balanced breakout cable? Can't try that since I don't have it (yet)
I would be extremely happy if there was an easy solution to this...
Best regards,
Switters
