Asynchronous I2S FIFO project, an ultimate weapon to fight the jitter

I have tried to find a way to connect a receiverpi ddc to a stationpi pro and am unable to find an example. I know it has to be on Raspberry gpio .I have tried it at the base on the audio side, but I get a mute signal on the monitorpi pro, without the receiverpi ddc it works fine. Any help would be appreciated!

I’m very interested in purchasing a TWTMC-DRIXO master clock to integrate with my Ian Canada FIFO and HDMI Pro stack, feeding a Rockna Wavedream DAC via I2S. I don’t have builing soldering skills but i am willing tonpay a pro builder to make this happen !!

This may be not the best idea. The main place where a clock like TWTMC-DRIXO would really shine is if you change the clock of the DAC itself(or build a DAC with changeable clock). As far as clocks go the SC-Pure will be more than enough for streamer.

I'm almost positive this is a Station Pi Pro...I have the Station Pi SMT...and I know you can't plug anything into it, and this pic looks like it's got something plugged in on the right side

Mouse hoovering over the picture shows the "MonotorPiProStationPiController" (including the o instead of an i in Monitor.
And you're right about the extra board, that's part of the Pro.

At first thank you for the reply! So i have to forget about every masterclock?Cause of rockna wavedream or something else would be beneficial to my setup?

Thank you for trying to help! I had to order some very long 40 pin extentions to get it so the DDC and the pi would be high enough on the raspberry pi side of the stationpi pro so it would be above the sheilding barriers.

I don’t necessarily agree with this. Clocks have a big impact, use the best ones you can everywhere that fit the budget of the project.

I had some issues with 40 pin extensions myself. I'm trying to remember exactly what it was, but I found something somewhere about Ian's boards and how extensions can cause problems. I have the RPi 5 and I needed extra room because I bought the active cooler with the fan. I ended up, removing the extension, and adding a pacer on the 40 GPIO, and that gave me just enough room to clear it, and my problem went away. I posted about it here somewhere. I have had so many problems, mostly user error...LOL, that I can't remember all the details now. The good news is I have everything working right now. but I would not rule out the extension as being the problem. I think it wouldn't "lock" on on any thing over 44.1 mHz...I did have that problem too, and I think that's what it was...which is crazy...if you search my name I bet you can find it, it wouldn't have been that long ago, If you don't find it I'll look later...I'm about to eat dinner.

Using a HDMIPro and running MoOde Player, what "Name I2S Device" is used?
Right now I am using "IanCanada (i2s-dac)", but that doesn't seem to support DSD?

Playing a DSD512 converts to 24 bit/384kHz, and checking Audio Info shows "S16_LE, S24_LE" as supported formats for the Audio Device.
That should say something like "DSD_U16_BE or DSD_U32_BE" (as well).

ALSA mode is set to Direct, because in Default it gives a ALSA error.

I am missing something?

DAC is a Holo Audio Spring 3 Level 2, so both HDMIPro and DAC support DSD512 (and below and higher).

Hi,
Can someone confirm if the ES9038Q2M Dual Mono II dac works or does not work with 11.xxx/12.xxx MHz clocks? I know the document says that the dac works between 22.5792MHz to 98.3040MHz. I have a coupe of clocks I want to try out with the dac if possible.

Thanks.

Might be useful for someone; I tried 11.28Mhz and 12.28Mz clock with ES9028Q2M Dac board and it worked. I guess it should work with ES9038Q2M dac as well. My guess is 5.6 and 6.14Mz should also work, but i have not tried them yet.

hello diy'ers 🙂

are there any stationpi's that work with transportpi digi 2?

the manual seems a bit vague and i'd like to know if anybody used any stationpi successfully with digi2.

im still in planning phase for a second system and im not sure if digi2 would fit my idea so far 🙂

thank you very much, gents

I did a quick read of the manual for HDMIPro and there is no mention of what software or drivers.

I've always been confused over what Linux drivers and configs are required for a given IanCanada stack, especially when it comes to DSD support, hardware volume, etc. Maybe there is a document somewhere that I've missed?

I checked those too, and when it comes to drivers iirc I saw it being mentioned there is one in moOde Player. That's it.

DSD support, from what I've gathered in forum posts is that info should mention it if supported.

I could try a different player to see what happens there.

there is some difference in sound.
i did it with a neutron star external clock and sinePi.
removed the clock from the ES9038Q2M Dual Mono II and made the mclk dual mono to the fifoPi-Qll which in turn is connected to the neutron.

SinePi and the NewClassD Neutron Star2 Audio reference clock

Neutron Star2 has a main high quality sine wave output in SMB coaxial cable connector though the built in sine to square converter output is not good enough.

SinePi makes the NewClassD Neutron Star2 Audio reference clock working great for FifoPi and ReclockPi. As well as all other sine clocks.

SincePi and Neutron Star2 can have three different configurations
1.One Neutron Start2 since clock
2.Two Neutron Start2 since clocks
3.One Neutron Start2 since clock and one local XO clock...
