Could you tell me where you got your dir 9001 board from please. It looks very different from the one I have.

Didn’t manage to get the link working, but here’s a picture from the seller on AliExpress:

I have used this one, although the one I received was a bit different. https://www.aliexpress.us/item/2255800052122243.html

Thank you, yes I had already managed to find it on aliexpress before I saw your post.

Your board is more or less the same as mine but mine has a toggle switch between the coax/ spdifsockets to switch between the two. It seems like there are a few variations.

Interesting video from Vincent Fong. Subtitles available. Many other interesting videos on his YT channel.

Brief feedback: It was due to the RCA sockets. When soldering, the pins came out a bit. I heated them up again and pressed them in.
Another question. You said somewhere that you can use the Innomaker DAC as a reklock for the TDA 1387? I have the DAC Pro Hat ES9038Q2M. How does the whole thing work?
RE: ProtoDAC TDA1387 X8 project - hifinet - 03-31-2025
It looks as though the Innomaker DAC Pro HAT should work (perhaps you can confirm), since it is a master DAC with two crystal oscillators and has a topside GPIO connector. Setup Moode so that it works with the Innomaker DAC. The Innomaker will then reclock the I2S, and the reclocked I2S will pass through to the topside GPIO. Install ProtoDAC to the topside GPIO.
