I searched about this and found there is no such method in uwp can access the setting of Xbox, why do you want to access it? Can you show more details about your expected behavior?

Hello,

Welcome to Microsoft Q&A!

You cannot query these settings directly but you can infer their values by using the following APIs:

Speaker Settings:

Using C++: https://learn.microsoft.com/en-us/windows/win32/api/audioclient/nf-audioclient-iaudioclient-getmixformat

This is a win32 api, you can not directly call it in C# unless you project the calls from C++, you need to p/invoked these APIs in C# from C++ to use it.

Headset format:

You can try to use the APIs from this document to infer the value: https://learn.microsoft.com/en-us/uwp/api/windows.media.audio.spatialaudiodeviceconfiguration

Hi,

My project is in C# and guide me how to project calls from C# to use C++ api. Also checked this api which property should i use exactly to fetch setting selected for speakers in xbox.

Also this api
https://learn.microsoft.com/en-us/uwp/api/windows.media.audio.spatialaudiodeviceconfiguration, seems for spatial audio which contains audio format which is in SpatialAudioFormatSubtype which throws access debied if i try to set that format and if you check active spatial format it is showing GUID which is not at all matching with all these GUID.

Thanks for any help

About how to use c++ api, you can refer to this document, the IMemoryBufferByteAccess is also c++ api. You could try to use IAudioClient::GetMixFormat to check Speaker Setting. About the issue of this api, I will still ask the team about this.

About setting format, it's by design. We do not allow apps to change the spatial format.

Hi,

IAudioClient::GetMixFormat will this method return actual setting selected in speaker setting of xbox audio and sound setting like Bitstream - Dolby Digital, Bitstream - Dolby Atmos For Home Theater, Bitstream - DTS sound, 7 Uncompressed , 5 Uncompressed, Stereo Uncompressed etc? Why spatial audio api is not useful as that is the only api which have atmos identification.
