How to make XAudio2 throw a Device Lost flag/error?

Question

Hi,

I was wondering how I can produce a Device Lost message for XAudio2. I tried using the dxcaps -forcetdr command in the Developer Command Prompt window for Visual Studio, but it did not work. I am using C++ and programming for Windows 10.

Answer 1

HRESULT hr = XAudio2Create(&pXAudio2, 0, XAUDIO2_DEFAULT_PROCESSOR);
std::cout << "hresult: " << hr << std::endl;
if (hr == XAUDIO2_E_DEVICE_INVALIDATED) std::cout << "XAUDIO2_E_DEVICE_INVALIDATED";
if (hr == XAUDIO2_E_INVALID_CALL) std::cout << "XAUDIO2_E_INVALID_CALL";
if (hr == XAUDIO2_E_XAPO_CREATION_FAILED) std::cout << "XAUDIO2_E_XAPO_CREATION_FAILED";
if (hr == XAUDIO2_E_XMA_DECODER_ERROR) std::cout << "XAUDIO2_E_XMA_DECODER_ERROR";
if (hr == S_OK) std::cout << "S_OK";

You just need to use XAudioCreate to match XAUDIO2_E_DEVICE_INVALIDATED.

Don't forget Initializing it before using it:
CoInitializeEx(NULL, COINIT_MULTITHREADED);
