HALO DAC I2S question

So I installed the PS Audio cable that came with the Airlens and it worked fine. I don’t understand why that cable works but another I2S cable wouldn’t but it’s working and I’m happy. 

Any pin configurable device will match up with partnering device, there are 8 possible settings, one will work. @jazzman7 may have given you possible reason it isn't, otherwise you don't have correct configuration.

I do not own a Holo May DAC, but a very good friend of mine does. As I understand it, is that the PLL on the Holo May can conflict with I2S.  I suggest turning PLL off when attempting to work with I2S. My friend decided this was too much of a PITA, as his principal source is a Lumin U1 via USB. He has a Shanling CD transport which is I2S capable, but finds it easier to just use digital Coax.

Did you try all the optional i2S settings for both the Airlens and the CD player?  If so you may just be out of luck, and I’d contact Holo for suggestions.  It is most likely not the HDMI cable as most will work fine unless you’re using some obscure cable of some unique design. 

Thanks. I did try that and still nothing….

The Holo May has multiple I2S settings.  You need to use the correct one.

My guess is that you will get the best results with ALT2 which is the pinout setting compatible with PS Audio.

Suggest trying that.

So a I2S specific cable would not have the right pins? How do I know what cable to purchase?

MY first guess is the pin out on your HDMI cable isn't compatible.
