stereo streaming with only 2 nrf5340 audio dk instead of 3

[assegid]

I have managed to use 3 nrf5340 audio DKs one configured as Gateway and the other two as left and right headsets to stream stereo audio. My question is, what do I need to do to configure only one nrf5340 audio dk to receive stereo and hear the stereo stream through the headphone jack? it seems to me it should be easy to modify one of the provided examples to accomplish this, but I could not do it. Can you help me?

Do you know Nordic's reason for using a mono decoder to connect to a stereo headphone jack?

Nordic's rationale seems to be that the nRF5340 Audio DK was designed exclusively to demonstrate the nrf5340_audio application, which highlights the CIS feature of two separate BLE receivers playing synchronized stereo audio, so each ADK "earpiece" only requires a mono output.

I haven't attempted to integrate a stereo DAC myself so cannot confidently comment further, but Nordic support has some helpful reference links that they'll likely share to explain the necessary steps involved, and maybe other devs have appropriate hardware recommendations.

Please let me know if I am still missing something, but I don't get the rational for demonstrating synchronization using 2 DKs instead of one. Will work on finding a suitable codec that allows stereo listening.
