I have my BC127 set up as I2S slave with my host transmitting my I2S at 44.1kHz. I have the BC127 configured with:
AUDIO_DIGITAL=0 44100 64 100200 ON
Whenever I pair to a device, the connection switches to 48kHz as seen here:
STATE CONNECTED[1] CONNECTABLE[OFF] DISCOVERABLE[OFF] BLE[OFF]
LINK 10 CONNECTED A2DP F80FF9F8C973 SUSPENDED SBC SRC 48000
LINK 11 CONNECTED AVRCP F80FF9F8C973 STOPPED
Once the device is disconnected and I check the AUDIO_DIGITAL output, it shows 44.1kHz again.
