Hi,
we bought OM13092 Dev kit and started working on the Audio interfaces. we are not able to test Audio Loopback functionality in the board.
our idea is to loop back Analog MIC to Analog Audio out in CODEC loop back mode. we took usb_rom_device_audio example code and changed WM8904_AUDIO_IF_0 (0x18) = 0x0150 and trying. we are not hearing any sounds made in MIC to the Audio out.
Since we are enabling Digital Loopback, we have removed JS8 and JS9 on the Dev kit.
but when we try voice recording through the same MIC , we are able to record the audio and we are also able to hear the recorded voice through Audion out by using the above example code usb_rom_device_audio.
please can you help am i missing any other points?
