Looking to fabricate a HDMI cable to carry audio I2S signals from a PS Audio transport to a Holo May DAC. What is the correct 19 pin HDMI pinout diagram? Is this one correct?
|1| GND — Ground (Common ground for signal integrity)|
|2| LRCK (Word Clock) — Left/Right Clock (Word Clock, syncs audio)|
|3| GND — Ground (Common ground)|
|4| SCL — I2C Clock (optional for device control)|
|5| SDA — I2C Data (optional for device control)|
|6| GND — Ground (Common ground)|
|7| SD (Serial Data) — I2S Audio Data (main audio data stream)|
|8| GND — Ground (Common ground)|
|9| MCLK — Master Clock (DAC clock synchronization)|
|10| GND — Ground (Common ground)|
|11|+5V — 5V Power (used for signal integrity, optional)|
|12| NC - Not Connected (Unused)|
|13| NC - Not Connected (Unused)|
|14| NC - Not Connected (Unused)|
|15| NC - Not Connected (Unused)|
|16| NC - Not Connected (Unused)|
|17| NC - Not Connected (Unused)|
|18| NC - Not Connected (Unused)|
|19| GND — Ground (Common ground)|
Thanking you in advance — Pete

Here is a link to a chart that Jesus from Sonore compiled a while back. Not sure how “current” it is but it has the usual suspects in it including PS Audio.

For Triode Pete. I posted a similar question a few days ago and this thread was cited. I wonder if you had any luck in fabricating a correct HDMI cable.
Thanks
Yes he did, he posted about it in his section on Audio Circle.
Yes, it worked out very well sonically!
Cheers - Pete
Pete and Dawkins, thanks for the replies.
I studied Pete’s original post #1 and the Sonore spread sheets referenced in Dawkins’ post #2.
Just to be sure I understand, I’m assuming that the pin-out in Pete’s Post #1 is the plan endorsed by both of you.
Many thanks,
Warren
Hello Warren - Please use Dawkin’s attachment. That’s what I used and it worked brilliantly.
Sorry to be dense; there is a lot of data in the attachment. I see two identical PSA pin-outs. This one for the Power Wave DAC an seems the most likely.

Yes, the pinouts were the same for all of the DACs from the Perfectwave forward as well as the disc transports.
