At the moment, the firmware makes use of TDFII biquads for all filters. This results in a somewhat elevated (though inaudible) noise...

Wow, how did you manage to improve it by that much? Sounds (heh) like magic

The SPDIF input branch is available now on the GitHub repository for anybody interested in building, testing or contributing. It is not...

It will be on GPIO 11 by default and will be assignable. I will be pushing the relevant commits to a new SPDIF input branch while I...

Are you able to read the SPDIF control bits? I want to check if I’m able to parse the LG Sound Sync status and volume with the SPDIF...

We now have working SPDIF input. This is currently experimental but a production ready implementation is never too far away. :)

DSPi Firmware v1.1.1 is now available with full support for 24-bit input and 24-bit output via USB and SPDIF! As always, I highly...

I expect to push a new release later this evening, which will include 24-bit USB input and 24-bit SPDIF output. :) Switched SPDIF input...

Loopback measurements look quite satisfactory. There remain a few minor issues to address, at which point I will be pushing a new release.

Thank you! :) 96KHz is fully supported but making use of it will halve the number of DSP instructions available without providing any...

I highly recommend to use a Pico breakout board. The yellow LEDs indicate the active GPIOs and any changes can be easily accommodated...

This might be possible if the HDMI-I2S board provides a set of clocks, which it should. The idea would be for the Pico to operate as an...

The problem becomes that upstream devices deliver their clock to the downstream device and you would need an asynchronous sample rate...

Slightly off topic but would it be technically possible to have multiple I2S inputs like from those HDMI to I2S boards so we can mix...

That's good. The maximum recommended sample rate is 48KHz, as doubling it to 96KHz halves the available DSP cycles without an audible...
