Hello, I need to play short sound on CYW20706 HFP device when I turn on the device. I know that some functionality as voice route is disabled. But each HFP wireless headset has welcome sound. So how can I send short sound via pcm to speaker?

I guess you will need the audio insert function which is not supported by CYW20706.
The function is supported by CYW20721 device.

I can't change microcontroller because I've bought a lot of chips and pcbs are ready. I think that I can put array address direct into pcm peripheral register or something like DMA. But I need address of this peripherial.

Very sorry the interface is not exposed to the application level. You may take a look at the codec, some codec has the function to add some audio/voice data.
