nrf5340_audio:How to hear sound in the right headset?

[liuzong]

Hi,

I'm running some transceiver tests to look at extended broadcast and ISO transfer modes. I am using  nrf5340_audio_dk and ncs V2.6.0 to run nrf5340_audio application. I have saw this in here. First I can hear in my left ear. Then I press the reset key while holding down the 1 key according to the instructions. The log shows that the current receiving end is right device.

After testing, I could determine that the receiver of headset had indeed changed from BIG1 to BIG2. But the truth is I can still only hear in my left ear. What else do you need to do if you want to hear the sound in the right ear of the headset?

Best wishes，

Liuzong.

Yes, this is correct. The CS47L63 codec is a mono device, and while it can transceive multiple channels, it is hardwired to only the Left output on the Audio DK's TRS headphone connector.

It is possible, however, to mix multiple channels into a single mono signal so that they can all be heard in the Left output simultaneously, but this requires editing the /src/drivers/cs47l63_reg_conf.h file which contains the register settings that configure the CS47L63 during operation.
