What are you planning to use for supply to the isolator?

Is there much point using the same supply to the isolator chip and the main 5V supply to the WaveIO?

For what its worth I'm about to hook super reg ssr01 to isolator +V and run waveio from usb power for first test run. DAC build isn't complete but starting with a WM8741 in stereo, dual mono waiting for rest of the audio chain to be tested and operational.

After things are confirmed working and tweaked I am hoping to test properly terminated u.fl with LT1085 supply to WaveIO to isolated i2s output with low noise supply to isolator.

why not remove all the on board connectors just direct connection between solder and wire...aren't that suppose to be the 'ultimate connection' either for coax or isolated output...!!!!

Default Driver update

Hello guys,
I want to let you know that there's a driver update for WaveIO card available here. It was released by Thesycon/XMOS last week. After some time testing it I've notice that few issues were solved with this release. Please feel free to test your WaveIOs with it.
Kind regards,
L

Take it this is for the Windoze machines?

Thanks Lorien,

Default matching problem with discrete dac from diyparadise

I match it with the discrete dac from diyparadise malaysia.
It works but there is a constant low level distortion with soft music . the distortion is absent in between tracks or on pause.
I am using window 7 in a fanless ATOM based pc and Foobar .
The digital isolator is powered at 3.5 V via a salas shunt regulator that was proven to work well in another Tenor based converter.
Any idea what the cause ?
thanks

@ PET-240: yes, drivers are for Windows OSes.

@ kp93300: Try to use external Power supply: 5V @ 0.6mA minimum (please do not cross 5.8V limit). For this you'll have to connect the external PSU to J13 screw-type connector and switch the jumper on J12 pin header from "USB" to "EXT" position (check the back side of your WaveIO card for Silk screen text).
Please let us know if there's any improvement,
L
