Windows application volume mixer - c++

Question

I would like to list the applications displayed in the windows volume mixer.
In this example, "sons systeme", "Windows" and "spotify"
I write some code and I´m able to count and list those applications. The problem is I cant fetch their name nor their icon path
Here is the output :
Session Name:
Icon path Name:
Session Name:
Icon path Name:
Session Name:
Icon path Name:
Session Name: #%SystemRoot%\System32\AudioSrv.Dll,-202
Icon path Name: #%SystemRoot%\System32\AudioSrv.Dll,-203
I don´t understand why I can´t fetch this kind of data.
Here is my code :
IMMDevice* pDevice = NULL;
IMMDeviceEnumerator* pEnumerator = NULL;
IAudioSessionControl* pSessionControl = NULL;
IAudioSessionControl2* pSessionControl2 = NULL;
IAudioSessionManager2* pSessionManager = NULL;
hr = CoInitialize(NULL);
// Create the device enumerator.
hr = CoCreateInstance(
__uuidof(MMDeviceEnumerator),
NULL, CLSCTX_ALL,
__uuidof(IMMDeviceEnumerator),
(void**)&pEnumerator);
// Get the default audio device.
hr = pEnumerator->GetDefaultAudioEndpoint(eRender, eConsole, &pDevice);
hr = pDevice->Activate(__uuidof(IAudioSessionManager2),
CLSCTX_ALL,
NULL, (void**)&pSessionManager);
hr = pSessionManager->GetAudioSessionControl(0, FALSE, &pSessionControl);
// Get the extended session control interface pointer.
hr = pSessionControl->QueryInterface(__uuidof(IAudioSessionControl2), (void**) &pSessionControl2);
// Check whether this is a system sound.
hr = pSessionControl2->IsSystemSoundsSession();
int cbSessionCount = 0;
LPWSTR pswSession = NULL;
IAudioSessionEnumerator* pSessionList = NULL;
hr = pSessionManager->GetSessionEnumerator(&pSessionList);
hr = pSessionList->GetCount(&cbSessionCount);
std::cout << cbSessionCount << std::endl;
for (int index = 0 ; index < cbSessionCount ; index++)
{
hr = pSessionList->GetSession(index, &pSessionControl);
hr = pSessionControl->GetDisplayName(&pswSession);
std::wcout << "Session Name: " << pswSession << std::endl;
hr = pSessionControl->GetIconPath(&pswSession);
std::wcout << "Icon path Name: " << pswSession << std::endl;
}

Answer 1

You can retrieve the name by using the ProcessID
DWORD procID;
pSessionControl2->GetProcessId(&procID);
And then with the ProcessID you can get a handle of the program and find the name and icon.
