I don't use any usb cable.The hiface two is connected to the aqvox power supply as shown here :

then this connector is hooked to the motherboard of my pc daw.

In my next audio daw i'll use this card to filter out ubs noise coming from the pc :

I just installed a HiFace 2 and find that my 2.8GHz C2D MacBook Pro sometimes skips playing 24/192.  I know this is not a new machine, but this machine was not running much and is equipped running a dual drive 7200RPM RAID 0 and 6 GB of RAM.  Using iStat Menus, I can see that there is plenty of CPU overhead and memory.  Does anyone have ideas here?  I'm testing out Amarra with this adapter, and it's possible Amarra has something to do with it.  Thanks!

Try iTunes, try optical.  Might be the software or HeadRoom.  Don't have a Mac but try not using anything fancy either, if it was a PC I'd say no WASAPI, ASIO or KS until DS is working.

old model issue.read here :

" I did wrote you already, there was no problem with our powersupply, the version you bought from italy is just an old model, we informed our dealers some months ago to send back old models for update - but your dealer did not send them back for update obviously. And it is not our fault that you did pay high-customs -but I would also be nerved."

Thanks, everyone.  I can't use optical at 192 as a limitation of the built-in driver, but I just increased the preload amount to 1GB, and that seemed to take care of it!

Does anyone else having issues with HiFace2 occasionally disappearing from the system on Windows 7? Replugging usually fixes the problem.

HiFace2 output a normal 500mV spdif output.  HiFace1 output 5V!  Which is why it needed an attenuator ;)

Select whatever you use for your normal Windows sound as the default (onboard sound or sound card). That alone may solve your problem. It will also prevent Windows from trying to access the Hiface for normal Windows sound. I assume you are using some form of bit perfect output selection in your software player (Foobar, JRiver,etc.). I use the Hiface with Foobar set for kernal streaming and it works perfectly. After making the same mistake as you, I did have to reset things by powering down and holding down the power button for 30 seconds. That reset the computer to look again at the usb ports during boot and completely solved the problem.

even later with this reply

i use only my headphone system for pc sound.

i do not have desktop speakers.

this is why my hiface is set as default.

HiFace One was rock stable. :( Hopefully next driver version will fix it. One other thing that I have noticed that even when playing in KS mode, volume changes in Windows Control Panel/Sound does affect output volume. Isn't that done via kmixer which supposed to be bypassed?

With HiFace One I could completely disable the sound in Control Panel and still have it playing via KS in foobar2000.
