I received my Hifiberry Digi some months ago (order 17333 from december last year). I have tried to lock my Wadia X32 DAC to the Hifiberry Digi, with no luck as of today. I tried different combinations and configurations of squeezelite. I also tried with the test distro found on the site. What I observe is that the led on the Wadia sparkles, and I can hear at best a tiny buzz.
Note that I ordered the version with output transformers, if this matters.
I could not test the card with another DAC (I only own the Wadia, which works perfectly with my CD player).
Have you got reports about that kind of configuration? Is there anything else I could try?
Thank you for your help.
