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.

Hi,

CONFIG_AUDIO_SOURCE_USB is default option. 

Is gateway working normally as long as you do not do manual reset by pressing Reset button?
Were you able to restore audio on the headset side in any way after manual reset of the gateway (possibly by shutting gateway's power off/on)?

No, the USB audio is not intermittent. When the Gateway starts, it works briefly for less than a second and dies and never comes back.

Does audio ever come back on the headset side?

Best regards,
Dejan

I am not sure what you mean normally, It is not sending the audio data it receives from the PC through the USB cable. Whether I use the reset button or power cycle the Gateway board, the audio only gets transmitted to the headset boards for about 0.25 sec and dies never to recover.

Not unless you reset the gateway when it will work for another ~0.3 seconds.

Today, I tried it on a newer M3 macbook pro and the result is the same except it seems it works a bit longer. 0.5 - 0.8 seconds.

Hi,

You could try to switch devices' roles by programming the device which was previously gateway as headset and headset as gateway. What is the result?

Best regards,

Hi.

I also struggled with the issue.

But changing sample frequency to 44100Hz fixed this error.

&usbd {

    hs_0: hs_0 {

        compatible="usb-audio-hs";

        mic-feature-mute;

        mic-channel-l;

        mic-channel-r;

        hp-feature-mute;

        hp-channel-l;

        hp-channel-r;

        hp-sample-rate-hz=<44100>;

    };

};

I have tried that many times. It didn't help.
