Sorry, I just now realized I may not be using the “@” tool right. My apologies for the multiple posts above.
After you start editing a new post you can go back and press the button on another post and it will paste that post into the edit box (at the cursor). That way you can answer more than one post in in a single post.
Also the rough schematic for the PS Audio implementation of I2S over HDMI & LVDS is just below the PS Audio columns in Jesus’s chart.

If you don’t mind my asking what MB are you using? I assume you are using the Botic driver from Miero.
Kevin said schuerholzklump238: Technically, resistors and capacitors should also be considered "computer parts." The trick is isolating the computer parts from the audio parts... and using I2S to talk to DACs.klump238 here :)
Right, but the worst thing I know (in general) is when you see the back plate of a cost no object music server and you immediatly discover by the connectors that a standard HTPC motherboard is ‘thrown’ into the player.

The info is right, although we may pass a master clock… just for fun.
Nope, not the BeagleBone Black. We’re using an A20, and an I2S driver I helped write on the mainline kernel.

Sure, I understand. This device doesn’t use a PC motherboard. It does use a processor board and it runs a flavor of Linux.
In the early days, we made PC based systems (Windows). I went as far as I could go with sound quality. Then I tried a high-end UPnP board with dismal results (from a sound perspective). So I started from the ground up.
The board runs the mainline kernel with an I2S driver and the USB Class 2 driver. It also runs the Roon Labs RAAT protocol. And a tiny configuration system, so you can grab updates on demand from the web.
It doesn’t run UPnP, MPD (or any “player” software for that matter), a desktop interface or any other applications. The Master Mode player uses a PLL to drive the I2S clocks. The A Cappella Network Player has its own isolated clock board that times the audio signal coming from the RAAT protocol.
This thing is a PC in the same way a graphing calculator is, which is not very much. It does one thing: clock audio data (Ethernet input, isolated or not) into digital audio signals (I2S, AES/EBU, S/PDIF [BNC or RCA via adaptor] and USB.)

I updated the database. Good idea to pass along MCLK. Sounds like a cool project…we should chat some time.
Kevin said tarnishedears: Send me a note if you're interested in connecting an RPi (or other device) to your DAC. We spent a ton of time working out the details.PM sent!
harbapapa said To TarnishedEars:Thank you, Harbapapa! And especially thanks to Linvincible! My Raspberry was not in use for almost one year. Finally I ordered this I2S-to-HDMI module from Audio-GD. Well, my module looks different a bit. Biggest downside are the missing screws beside the HDMI connector. Is it possible to add them?…and yes, Harbapapa is me!
Apart of this everything works as hoped! I use the piCorePlayer, rock stable that! My old SBT serves as “Now Playing” screen for this extern (piCore-) player. I enjoy the Torreys beta with this solution very much. Btw, I have sold my Bridge II.
Waiting for the HDPLEX 100W LPS now.

The screw holes besides the hdmi port were just hex hollow screw holes (I don’t know how to best describe that) soldered to the large copper ground on each side of the port.
These “holes” are exactly like the small screws on the back of PC cards (vga/DVI/DB9…) you can take any of those and solder them on the card on one of the flat sides
just make sure you do not burn the card…
good luck!

Hi Linvincible,
thank you for the quick response. Indeed I still have a box with old computer parts somewhere. I will take a look at it later.
Besides, I am going to order a second I2S-to-HDMI module. Just in case… lol.
Thanks again!
Mario
P.S: I just found these hexagonal braces(?) on audiophonics.fr
holzohr this is interesting info. I have a SBT I use with my DS, and I have a Pi lying around. I’d like to get past the 24/192 barrier and play some 2xDSD files from my LMS library. Can the Pi go that fast with piCorePlayer?
Hi Dvorak,
DSD128 should work when you connect the Raspberry via USB. I had the Pi in use that way with my former DAC (Oppo HA-1) but had to place a REGEN in-between to make the sound “pleasant” to me.
May I ask which I2S Driver you selected to pair with the Audio-GD card on your Pi?
TarnishedEars said May I ask which I2S Driver you selected to pair with the Audio-GD card on your Pi?The generic I2S driver.
P.S. Pics say more than words.
Very helpful. Thanks! Is that just an old Raspberry-Pi B+ that you are using?
No, it is the Raspberry Pi 2 Model B.
My new I2s streamer based on Pi3 (and Moode 2.6 TR5) is finally ready. Linear psu with Belleson SPHP 10A regulator is great.
This is the best source for the DS I ever had
That is amazing! Can it support DSD128 and DXD?
Unfortunately not.
DSD64 and 24/192 are the limits, currently
