What will it do HDMI through i2s input?

I has seen some warnings about not putting HDMI signals in to an i2s input, But I am curious…What will it do to the DS and how or why?

Not that I think it would work, but what would it do damage wise?

Just curious


There shouldn’t be any damage on DACs but nothing good can come out of it either. On transports things could be unhappy since both ends may be trying to drive the wires at the same time. I think the tone of the warnings is probably of the “don’t expect to use HDMI on the HDMI connectors of the DS, DS Jr, PWD, etc.”

Thank you

Just to confirm - I’d like to send an audio measurement signal (REW) from my PC to my DSJ. Since the DSJ only accepts digital signals i would need output from my PC’s HDMI port to the I2S input.

Is this a NO GO?

I believe this is a NO GO.
I2S uses HDMI cables but in no way follows the HDMI protocol.
You need a digital output from your PC - a USB soundcard would do the trick, if it has digital out.
Does the DSJ not have a USB input?
