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.
HALO DAC I2S question
I just received my new HALO MAY DAC and in trying to hook it up to my PS Audio Airlen’s I get no sound with the I2S connection. It works fine with a digital cable hook up. The same thing happens with my CD player trying to use the i2s connection. I’m befuddled.
