Unfortunately, I'm off to work now. I'll have a look at that tonight.

Just wondering, is it normal to hear a slight soft static sound when the usb indicator goes green? I have my headphones directly plugged into the DAC, which might be the issue.

It's not so much as the transition from red to green, but it actually makes a continual static sound as soon as the usb sound is activated. It's pretty soft, but noticeable with my AD700's.

I had this with an alien dac.

IT was ground noise from the usb. try it on another pc to verify. My main pc has a noisey usb line, my laptop is super quiet.

Hmm, your right, my notebook does not seem to produce any noise at all.

Is there anyway to remove this problem form my main pc? I don't mind building something if it will work.

I performed the tests as requested. All pin => pad resistances are super low, all pad => pad resistances are super high (except for the connected ones).

Is it buggered?

some strange things... I connected my toughbook (windows XP) to the DAC last night and it wouldn't work. I went through the settings and everything was OK. I had to restart the toughbook with the DAC connected to get it to work. I have it at my job this morning and hooked the DAC to my work computer (vista) and it just started to work without the need to change any settings. I am not computer savvy in the least, but this seems strange.

Do you get the noise while the selector switch is "green"? If you only get it while it is red this is normal.

Also is it connected to a hub or directly to the computer?

vixr - You may need to make sure the usb audio device is selected, most systems will not select it as the default if a playback device already existed in the system. Also make sure you are not going through a usb hub such as the ports on the keyboard or monitor, connect it to the computer.

I get the noise when its green, and during playback if the volume is low and not masking it.

It's connected directly to my pc, although not the motherboard jacks at the rear but through a usb cord to the internal jacks (case jacks).

I could not solve this with my pc with the noisey usb line (this is the alien dac).

maybe a hub would help, but then you can run into other issues.

One pc, dead black background. The other noisey.

you will struggle to find an answer to this on the net - i gave up.

Have you tried seeing if powering the DAC from an external source makes a difference?

how about using a old PCI soundblaster to get the digital output?

edit: duhhh, just realised you are talking about the alien dac!
