It sounds like you are encountering a clock collision. When DSPi switches to master mode, both it and the ADC are outputting clocks. The simplest solution here would be to reconfigure the ADC for slave operation and run DSPi as a master for both input sources.
This is actually a firmware bug rather than an issue with Console and it will be squashed very soon.
After much deliberation, I decided to assemble all six amplifiers in a single case, with the speaker housing only the drivers and connectors. A single power supply, short HF connections, and a single DSPi make amplifier configuration easier, easier to maintain and modify, and less expensive, no need to connect power to each speaker. Cooling is also better for the amplifiers, and vibration is reduced. For initial experiments, you can easily use existing speakers; just disable their crossover. Long speaker cables aren't a problem, and they're an advantage for Class D amplifiers. They have a choke and capacitor at the output anyway, so the additional inductance and capacitance of the cable isn't a problem at all.4. Or something else
Yeah I just dont want 3 or 4 pairs of cables running from my amps to the speakers. That's kind of the prerequisite. Looking for alternatives that house the amp(s) in the speaker
Your aversion to four cable pairs is understandable. However, Speakon connectors and a dressed wire harness are not completely hideous. See my LX-521 speaker installation. Note: Some consider the LX-521's a hideous abomination; Focus only at the cable exiting the left speaker to the wall.
You can put the box close to (behind) the speaker just like an external xover, so just signal an power in and neutrix speakon out.

I couldn't find any good simple balanced DACs so I made my own. They cost about $11 each ($16 w shipping and tariffs) in qty 20 at JLCPCB. I'm happy to share the gerbers and BOM if you're interested or maybe sell a few (at most 3 or 4) of the ones I built. They use the TAD5242 and measure very well. The design is for balanced output (one mini-TRS output per channel) since the output voltage is 0-3VDC. You can use them in single-ended but spec is to then use a blocking output cap, which the board has holes for. My build has no input connectors since I stack them 3 at a time for my 6-channel system.
I do have plans for an "official" plug-and-play device but there are a few core milestones that I need to reach with the firmware before designing it. We are about to have multichannel and slave mode support (spoiler!), followed by external interfaces (I2C, UART, mappable GPIO controls).
Once those major functions are in place, that will determine the shape of the official board and future additions such as ADAT will simply make use of the existing hardware. There are major advantages to a custom board, beyond just the convenience of built-in connectors. We can make use of an RP2350B with much more GPIO and replace the 12MHz XO with a much nicer 24.576MHz VCXO that will enable much cleaner (from an engineering, not audibility perspective) SPDIF and I2S outputs from SPDIF inputs.
Regarding funding, I am relying entirely upon donations and covering things out of pocket where possible. This was never intended to be a for-profit project and I certainly didn't expect to be upending the budget DSP industry! I think keeping the firmware/software fully open source and selling dedicated devices for those who value convenience is a reasonable compromise.
I believe this might be a known bug on GPIO 0 and 1 due to contention. Those pins will either be properly freed or made unavailable in the next beta. If you move the External Mute Control to a higher pin like GPIO 4, that should sort it out.
Can you please share download link. Thanks.
