I am aiming to connect the Gateway and Headset 1:1 and output stereo from the Headset.
The Gateway side is 16-bit I2S and the Headset side is 32-bit I2S, and I am able to output sound from the Headset in mono.
The I2C compatible ICs for both the Headset and Gateway are stereo compatible.
After referring to various answers on Devzone, I have reached a point where I can connect BLE but cannot achieve synchronization.
I have confirmed that the I2S waveforms of the three types of clocks are available on both the Gateway and Headset.
If the values of CONFIG_BT_AUDIO_BITRATE_UNICAST_SINK and CONFIG_BT_AUDIO_BITRATE_UNICAST_SRC are between 72000 and 80000, BLE can be connected, but if they are 96000, BLE cannot be connected.
What could be the reason for the lack of sync?
