nRF5340 Audio DK headphone output

[Nick_RA]

I've purchased a couple of nRF5340 Audio DKs for testing Auracast broadcast source/sink. Installed VS Code and have the sample apps built & flashed.

SOURCE: Sample app bap_broadast _source. Audio source is either line in from a phone headphone, or USB audio from PC.

SINK:Sample app bap_broadcast_sink using line out jack

Problem is I get no audio output. The sink is definitely connecting & receiving the stream according to the uart output:

Stream 0x20000f88 connected
Stream 0x20000f88 started
Enable: stream with codec 0x200079e8

(the disconnection is me powering off the source DK)

Is there a config change needed for headphone out?

[Amanda Hsieh]

Could you build with NCS v2.9.0 and provide the complete logs from the sink and source devices?

Also, check the Testing flow. 

[Nick_RA]

OK I am already using 2.9.0.

The user interface mentioned in the testing link doesn't exist, Is that written for a different sample app?

I'll start tomorrow with a fresh copy of the samples and capture logs.

Which of the board configs is best? From memory there is a choice of nRF5340 Audio Dk Application CPU, Network CPU and Non-Secure.

Thanks

Nick

This is after uninstalling everything and reinstalling a fresh copy of everything. I can build a sample app in vs code, so that's working.

Here is the output of Generate Support Information within vs code for what it's worth:

Happy to hear it works.

[Nick_RA]

<sigh> You're selectively reading and/or completely missing the point. IT DOES NOT #*%%$@ WORK!!

I meant reinstalling everything is working, because I can build a Blinky in VS Code. So cmake is OK in this context.

What you quoted here is NOT working!!!

Amanda Hsieh said:

Although building and programming using the VS Code Extension is not supported, you still can use the script or command line to achieve that.

To achieve your requirement with the nRF53 AudioDK, I think nRF5340 Audio: Broadcast source with CONFIG_AUDIO_SOURCE_I2S already can do that.

[Amanda Hsieh]

Sorry to misunderstand your reply. 

If you are using buildprog.py, please enable CONFIG_AUDIO_SOURCE_I2S in the prj.conf to build. 

[Nick_RA]

How is that going to help with 

FATAL ERROR: CMake is not installed or cannot be found; cannot build.

(did you actually read the output I posted? Are you a bot?)

In any case, I have already done that.
