Is it possible to make Raspberry Pi Dante enabled? Lets asume we have a sound card on RPi like hifiberry ADC+DAC.
As of 2024, you can put most Dante Products into AES67 mode. If you put an AES67 stack on your Pi than you can send and receive audio at 48 kHz and 1ms latency. So it's not full Dante capacity, but enough in most cases where a RPi is used. For the receiving case, there is an example gstreamer pipeline on Stackoverflow. Also pipewire is working to support AES67.
If you want "native" Dante, goldilocks comment still holds. You'd have to partner with Audinate to achieve this.
