Hello Michael, and sorry about the wait. Things can be a but hectic here during the summer.

What OS are you using on this computer providing the audio stream? If you are using MAC then you can try if this recently merged fix helps.

The sample rate is hardcoded in zephyr/subsys/usb/device/class/audio/usb_audio_internal.h, `.tSamFreq = {0x80, 0xBB, 0x00}` is 48kHz. This is simply 24-bit little-endian value.

Regards,

Elfving

Hi Elfving,

the example is set up in a way where Gateway is connected to the sound source and it send this sound over LE Audio to Headset where you can listen to the sound on headphones. I want to make this possible also on the Gateway sound. As the first step I just want to be able to listen to the same sound as on the Headset, in the next step I will try synchronize this as well, as in the end product these will be speakers, not headphones so sychronization is very important. Hopefully it make sense. I am really stuck right now, so I will apreciate any help.

Best regards,
Michal

What is this in addition to? You want it to act in addition to a headset device which it forwards it to?
