Issue with Stereo Sound from External Codec on nRF5340 DK (SDK v2.6.2)

[Abdulmohaimen]

Hello Team,

I am experiencing an issue with the sound output from an external codec connected to the nRF5340 DK. Currently, the sound is in mono, but my goal is to achieve stereo sound for both the left and right channels.

I read in an article that the configuration may need to be edited to enable stereo output from the external codec. I am using SDK v2.6.2 and would appreciate any guidance or suggestions on how to adjust the configuration to resolve this issue.

Thank you for your support!

Hi,

Could you please provide more information about your setup?

Which external codec do you use?

Best regards,
Dejan

Hi, 

Thank you for your swift reply.

I am using the DA7212 evaluation board, and I can hear sound from the jacks on the DA7212 board. I followed the instructions from Nordic to enable the external codec.

However, I am still working on achieving stereo sound, as the current output is mono. Any further guidance would be greatly appreciated.

Best regards,

Abdulmohaimen Algamoudi

Hey Dejans, 

Thank you for your support, and I apologize for the delay. I have been working hard to resolve the issue.

I have tried the provided code, but unfortunately, it does not work.

I also tested the  code mentioned in this tickt, and I was able to achieve stereo sound with CIS. However, there are some limitations, such as only one data channel (left) being transmitted

One of the problems I am currently facing is that the gateway cannot reconnect to the headset after it has been turned off. To re-establish the connection, I have to press the reset button.

I would now like to achieve a stable CIS connection with both channels (left and right) being transmitted. After that, I aim to implement it using a newer SDK version (I am currently using v2.4.2).

I have tried the approach mentioned in this tickt, but when I add CONFIG_BT_MAX_CONN=2_ to the prj.conf file, I encounter the following error from the gateway:

Should you require further details, I am happy to assist.

Many thanks in advance; I truly appreciate your assistance.

I forgot to mention that I am not using the configuration CONFIG_AUDIO_SOURCE_I2S=y, as my source is via USB. However, I am experiencing some issues with the microphone—when I use it, I only hear a noisy signal.

Hi Abdulmohaimen,

Would it be possible that you switch to newer NCS version sooner rather than later? The controller that was used in audio application before NCS v2.6.0 is deprecated and it is highly recommended that you update your NCS version. The most recent NCS version in 2.8.0.

Best regards,
Dejan

[Abdulmohaimen]

Hey Dejans,

I have been using the older SDK because it is the only version with which I have made progress so far. I currently have no issue with transitioning to a newer SDK. However, as I mentioned before, I was unable to make further progress with version 2.6.2.

I would be grateful if you could provide me with any steps or guidance to move forward with the new SDK and address potential issues, such as pairing and data rate problems.

Thanks in advance.

best regards 

Abdulmohaimen

Hi Abdulmohaimen,

In your initial post you mentioned NCS v2.6.2 but you showed the log when using NCS v2.4.2. Can you provide clarification on the NCS version you currently use?

Best regards,
Dejan

[Abdulmohaimen]

Hey Dejans,

While working with v2.6.2, I encountered some recurring errors.

I found the mentioned code of v2.4.2 from a previous ticket , implemented it, and it worked, allowing me to achieve CIS audio, albeit with limitations, as previously mentioned.

My approach was to continue working with the functional setup on v2.4.2 to find a concrete solution and resolve all potential problems. After that, I plan to update and attempt to achieve the same results with the newer SDK.

Best regards 

Abdulmohaimen

[Abdulmohaimen]

BTW, these are the log files from using v2.6.2 in a proper implementation:

Hi Abdulmohaimen,

Are these logs in NCS v2.6.2 obtained after you implemented the same code changes as when you used NCS v2.4.2?

Best regards,
Dejan

Hi Abdulmohaimen,

The error "<err> sw_codec_select: Unsupported channel mode for decoder: 0" in your NCS v2.6.2 log indicates that channel mode for decoder is not properly selected.

You can look at m_config.decoder.channel_mode, struct sw_codec_decoder and enum sw_codec_channel_mode for the place where channel_mode is set. This is how sw_codec_channel_mode looks like in sw_codec_select.h

enum sw_codec_channel_mode {
	SW_CODEC_MONO = 1,
	SW_CODEC_STEREO,
};

You could try to check how m_config.decoder.channel_mode is set.

Best regards,
Dejan
