Hi Frank,

As our understanding, I2S signal cannot be transmit too long.
There are some proprietary transmission standard, no matter from famous brand or DIY market,
enable I2S signal transmit longer.
I use a conversion board which convert I2S signal to their proprietary standard.
Signal convert back to I2S at my DAC.

So I need generic I2S signal like ODROID's I2S out.

Best Regards
Michael

Hi,

Actually, on my ODROID C1 plus case,
when I select ODROID DAC, I get I2S signal.

Via the conversion board, signal pass to my DAC. Sound very well. Nearly 60-70% performance compare with my CDM3 CD player.

If I provide better quality of power, performance
even better.

Best Regards
Michael

Slightly off-topic - different DAC and RPi 3, but this might save some frustration:

For my RPi 3 and HiFiBerry DAC+PRO. Hardware mixer is working by changing the
name for the device in the redis-cli command to "Digital" instead of "Digital Playback"
or "PCM".

Again, please note that this information is for the DAC+PRO not DAC+.

Thanks to all for providing the information on this topic.
