Windows10 version 20H2.
I followed every step-Getting started with XAudio2-How to: Initialize XAudio2.
The link is here. https://learn.microsoft.com/en-us/windows/win32/xaudio2/getting-started
The code worked before the update. But now when I try to do something like this:
pXAudio2->CreateSourceVoice( &pSourceVoice, (WAVEFORMATEX*)&wfx )
It is said the value of pSourceVoice is nullptr.
I'm sure I have done all these code down here.
Microsoft::WRL::ComPtr<IXAudio2> XAudio2;
HRESULT hr;
if ( FAILED(hr = XAudio2Create( &XAudio2, 0, XAUDIO2_DEFAULT_PROCESSOR ) ) )
throw Platform::Exception::CreateException(hr);
IXAudio2MasteringVoice* pMasterVoice = nullptr;
if ( FAILED(hr = pXAudio2->CreateMasteringVoice( &pMasterVoice ) ) )
return hr;
Is there anything I can do now?
I checked the Windows 10 release information, and did not find the 2021/4/20 update. Could you explain the details of which patch you updated and the problem occurred?
The current version is 20H2. OS build 19042.928. Yesterday system told me my version wouldn't be supported anymore,then it asked me to update. After the update was done, this problem occurred. Based on the release information, I think it's the 2021-04-13 update.
Here they are:
For Microsoft Visual C++ 2010
(KB 2565063)
For Microsoft Windows
Servicing Stack 10.0.19041.925
Feature Update to Windows 10 20H2 via Enablement Package(KB 4562830)
(KB 5001330)
And an unknown update
(KB 2504637)
I installed XAudio2 2.9, it works now. The former version of XAudio2 I used was 2.7 from DirectX 9.0c SDK.
So has the problem been solved now? It's just that the old version of DirectX is not compatible.
I guess it is. But I don't know why this happened after the latest update.
We have used the old codes for over 3 years.
There may be bunch of old apps crash because of this.
OK, I will confirm it with Internal engineer, and response here if there is any update.Thanks for your understanding.
Thanks and good luck!

@Hao Wu , The DirectX 9.0c SDK is very old. It is over 10+ years old so definitely the latest Direct X SDK is recommend to use. Please feel free to let us know if you still have issues if you are using the latest XAudio2 API.
