nrf5340 audio dk usb input issue

[assegid]

I cannot get the nrf5340 audio dk kit to work from USB input properly. After a reset, it only works for a fraction of a second and audio stops. Has anyone run into a similar problem? Please see attached video.

[Elfving]

Hello, and thanks for the video!

I rarely get videoes describing the issue here on DevZone. 

What NCS version are you using? For audio development I would recommend NCS versions <= 2.6.0.

EDIT: I mean NCS versions >= 2.6.0.

Regards,

Hi Elfving, I have been using 2.6.1. I will try 2.6.0 and report back.

Oops, I thought you were recommending 2.6.0 and older. 

Hehe understandably so, I see that I mistyped in my first response there. Sorry about that.

Could you check the log from the gateway, and see if it blames this on anything in particular? 

Regards,

Elfving

While flashing or during operation? Can you outline the procedure to get the log during operation without using VS Code?

[Elfving]

During operation. Use a serial terminal. I believe using it is mentioned a bit in this fundementals course.

We have one in VSC and nRF Connect for Desktop, but you can use any other as well. If you are using windows I hear tera term is good, I use termite for some reason.

If you are on linux, minicom is good.

It looks like I am experiencing the problem listed under 'Known issues'

OCT-2154: USB audio interface does not work correctly on macOS

Below are the logs from the terminals of the Gateway and the headset. It looks like a Log level of DBG would have had more details, but I did not know how change the LOG_LEVEL.

Can you tell me the config line to add to the prj.conf file to change the LOG_LEVEL to DBG?

Hi,

assegid said:

The only change I made is to the prj.conf file to enable and disable analog audio input using...

#CONFIG_AUDIO_SOURCE_I2S=y

In your prj.conf you should have CONFIG_AUDIO_SOURCE_USB=y. Can you check if you set this correctly?

Is CONFIG_BT_LOG_LEVEL_DBG that you want to use?

What did you pause (recording on the computer, or device)?
Known issue OCT-2154 is about intermittent audio stream on the headset side. Do you hear intermittent audio on the headset device, or you do not hear it at all after the reset? Does loss of audio stream occur sporadically as mentioned in OCT-2154?

Best regards,
Dejan
