nRF5340 Audio DK: Audio Loosing sync both with I2S and U

[Nambiar]

Hi All,

       I have been using nRF5340 DK audio with toolchain Version 2.5.2 and using the Audio Demo (nrf5340_audio_dk_nrf5340_cpuapp_common) for gateway and headset (Broadcast source and Sink). I have not changed anything and used script to build and flash the binaries.

• The source and sink is able to manage sync only for ~10s in I2S case (Audio in at Source using I2S). 
• The source and sink is able to manage sync for ~ 1s in USB case.

This means audio plays for 10s/1s and then the sink is unable to get the audio afterwards.

As it is experimental SDK any suggestion to improve it or am I missing any configuration.

Regards

Sainath

Hello Sinath, that sounds strange.

So you are testing the application using this documentation, and the buildprog script?

You have also not modified the sample app nor changed the LE Audio controller?

For flashing this is the link I used , For building and understanding this link.

• The source and sink is able to manage sync for ~ 1s in USB case.

By this you mean that the connection is lost after ~1s? And the audio wont play for longer than that?

Are you able to get the log from the device showing this happening?

The first intrinsic check is that the Sink is not playing the message, even though the payload shows valid data (had a check using sniffer). I can enable the logs if required , which of the log level should I enable?

[Elfving]

I see. I think I'll have to follow up on this next week unfortunately Sainath. 

Though just to mention it, this shouldn't happen. I had a talk with R&D now who has used this demo on tradeshows etc., and never seen this issue.

Regards, and hope you have a great week-end!

Ok , Thanks and Great Week-end to you.

Hello again Sainath, hope you've had a great week-end.

Could you start off by giving us the log from the application the way it is configured by default?

Could you also provide me the prj.conf settings that the project is using?

 Are the results (that it disconnects every 10 and 1 second) consistent? Does it still happen the same way?

Regards,

Sure , I will give them by next Monday. 

[Nambiar]

The disconnect is consistent the sync is maintained only for ~ 10s
