The nRF5340 Audio DK is configured to use the default USB rather than I2S (CONFIG_AUDIO_SOURCE_I2S is not set =y) and the earbuds are definitely paired with the S11 as I can play audio to them from the Internet.

Hi Susheel,

I programmed a nRF5340 Audio DK to be a Broadcast Source, it is recognised by Windows and I am able to play an audio file to it. It is recognised as an audio source by my Galaxy Tab S11 running Andoid 16 paired to Galaxy Buds3 Pro, the only issue is when I select ''NRF5340_BROADCASTER' as the Auracast Broadcast, I'm not hearing any audio. The Blue LED is flashing on the nRF540 Audio DK indicating that it is playing audio. Any ideas please?

Thank you Susheel, what should the nrfprog command be for the gateway please?

I think you first need to compile your program from headset or gateway with DCONFIG_AUDIO_DEV set to 1 as mentioned in this documentation and then select
nrfjprog --memwr 0x00FF80F4 --val 0 // for left headset and
nrfjprog --memwr 0x00FF80F4 --val 1. // for right headset
