Apple pi dac worked but R-Pi Dac was better and Allo recommended.. Generic I2S DAC was pants. The Allo dac Piano 2.1 crashed the RPi and corrupted an SD card.. I spy Kali reclocker on! Could those wires for be shorter in the final revision? Tough unless you can align the boards perfectly.. Remember sampling set at 32 I2S lift off soon...

Thanks - will use R-Pi DAC setting. Yes, will shorten the leads once I've got it working. I will also separate out the Pi power so that I have two cables feeding two different lots of 5V.
I had the Kali register music last night and checked by streaming from Qobuz at different sample rates. It worked perfectly until I started messing with the I2S settings. It's a bit touchy about it and I soon had an unresponsive Pi. Joining the club!

Martin
You remember my reference streamer from a few years, which you had to manually change the sample rates each time (same issue due I2s)I did get around this issue, by rewriting part of the playback software and configuring the off site DOB to talk together now all is need is to set the DOB software to auto flow or determined preset and it aligns the playback buffer spot on. Did take a while to get it right though!

Yeah, I'm having my own version of I2S issues here! I tried both RPi DAC and Generic I2S DAC and both settings result in a reboot and unresponsiveness. I'm too tired to re-burn both my SD cards and try again tonight.
So it's back to inspection and getting the Kali to do what it did yesterday. I may unhook the HDMI board and get it working using the sampling and buffer lights to verify that it's getting music as before. Then debug what's going on in HDMI.
Meanwhile, one card is going back into the old Pi so that I have some music tomorrow.
It's all good clean fun!

If dual to RPi the jumper needs to be off.. Hehe, suitable song lyrics Nobody said it was easy.. You fought the Pi and the Pi won.. Within the sound of silence.. I get knocked down, but I get up again..

Yes, jumper is off and power is separate. The thing is, I had it working with my SD card containing the previous build of Volumio.
All my new attempts were with the new build 2.526. Confusingly, the changelog refers to a 2.527 but the link is for 2.526.
I'm going to see if I still have a copy of 2.522 at home to use.

I've downloaded 2.522 and will use it as a test tonight.

Got S/PDIF up and working again, with 2.522. Going to leave that one running while I try and see what's wrong with the Pi/Kali one.

I suspect that the HDMI board is affecting the Kali in some way, so I shall remove it and get the rest up and running again. I can use the Kali's useful LEDs to determine that it's receiving music.

Hmm, Hard to know what to suggest.
How many earth's do you have. In theory one should be enough but 2 or 3 is possible / desirable.
You could also try the HDMI board straight on the RPi. Last resort though..
When I had the wrong dac settings in Volumio, RPi alone and RPi+Kali sounded the same..

I tried 2.522 and got the Volumio wizard up. Set it for RPi DAC and it wouldn't reboot into Volumio. Going to try 2.513 now (your version).

Bugger!
I did have a dieing RPi problem for a while.. racking brain.. try with only RPi / Kali pin 39 as gnd if not already like that..
Pin 34 and 14 could also be gnd. But I looked now & I only have pin 39 & 34 as gnd. 12 BCLK is on its own..
Are you using pin 29 MCLK?.. Najda can't use it.. Not sure what your HDMI I2S requires..

Progress! It looks like the ribbon extender cable that Audiophonics installed to take the SD card to the rear panel was intermittent. This caused more non-boots than successful boots. You just don't need that when you're diagnosing I used tweezers to push the SD card into the rather tricky slot at the bottom of the stack. I started with Volumio 2.513 and got the GUI up. Then I set it up for RPi DAC and rebooted. Kali now showed that it was playing music. Finally, I upgraded Volumio in-place to 2.526 and tested music into the Kali again. Still working. Now to work on the HDMI board.

Further progress: I bought the wrong HDMI board. The confusing wording has an HDMI input and I2S input and output, which are switchable. No good to me, but it's the final stage. Replacement board ordered, this one does PS and Gustard outputs configurable with a jumper. Nearly there!

Ah that's good!
This HDMI boards don't look very expensive so chalk it up to experience..

Indeed, the parts are cheap, it's the waiting that requires patience. However, I'm spurred on by knowing there are no Volumio/Kali compatibility issues with the latest version.
I'm still scratching my head over the 32-bit upsampling issue. The Kali spec says it supports 24-bit.

I've also found this one at AliExpress. Looks to be the transmitter version of the receiver board I bought in error. Also ordered, let them race towards me!

Next piece of the jig saw to fall into place.. I hate waiting too!

I've long learned to apply zen and just patiently wait! It's not as if my music isn't already sounding superb via S/PDIF
