I decided to release a little tool that I created to test the C++ part of my Default Audio Device Switcher that I built using DefSOUND for SoundSwitch.

The tester only uses the lib to list all the audio device found (that are active) and then when a device change state, it will display the change.

Update tooling for VS 2017

Same testing tool, with the possibility to switch audio device.

Used only for testing purpose.

Usage

s : toggle the default audio device
q : quit the application

You can find enclosed the code used to create the tester:

// AudioEndTester.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include "AudioEndPointLibrary.h" #include <iostream> #include <string> void do_work(AudioEndPoint::AudioDeviceList playbackDevices, AudioEndPoint::AudioDeviceList recordingDevices) { for (AudioEndPoint::AudioDeviceList::iterator i = playbackDevices.begin(); i != playbackDevices.end(); ++i) { auto audioDevice = std::move(*i); std::wcout << audioDevice->FriendlyName << L" : " << audioDevice->ID <<L" isDefault: "<<(audioDevice->IsDefault(eConsole)?L"True":L"False")<<std::endl; if(std::wstring(audioDevice->FriendlyName).find(std::wstring(L"Logitech")) != std::wstring::npos) { //audioDevice->SetDefault(eMultimedia); } } std::wcout << std::endl << std::endl; for (AudioEndPoint::AudioDeviceList::iterator i = recordingDevices.begin(); i != recordingDevices.end(); ++i) { auto audioDevice = std::move(*i); std::wcout << audioDevice->FriendlyName << L" : " << audioDevice->ID << std::endl; if (std::wstring(audioDevice->FriendlyName).find(std::wstring(L"Logitech")) != std::wstring::npos) { //audioDevice->SetDefault(eMultimedia); } } } void SetLists(AudioEndPoint::AudioDeviceList& playbackDevices, AudioEndPoint::AudioDeviceList& recordingDevices) { playbackDevices = AudioEndPoint::CAudioEndPointLibrary::GetInstance().GetPlaybackDevices(DefSound::Active); recordingDevices = AudioEndPoint::CAudioEndPointLibrary::GetInstance().GetRecordingDevices(DefSound::Active); } int main() { AudioEndPoint::AudioDeviceList playbackDevices; AudioEndPoint::AudioDeviceList recordingDevices; SetLists(playbackDevices, recordingDevices); AudioEndPoint::CAudioEndPointLibrary::GetInstance().Signals->DeviceStateChanged.Register([](AudioEndPoint::AudioDevicePtr device, DefSound::EDeviceState newState){ std::wcout << std::endl << device->FriendlyName <<L" : State (" << device->DeviceState << L")" << std::endl; }); auto signInfo = &AudioEndPoint::CAudioEndPointLibrary::GetInstance().Signals->DeviceDefaultChanged.Register([](AudioEndPoint::AudioDevicePtr device, ERole role) { std::wcout << std::endl << device->FriendlyName << L" : ROLE (" << role << L", "<<device->IsDefault(role) << L")" << std::endl; }); AudioEndPoint::CAudioEndPointLibrary::GetInstance().Signals->DeviceRemoved.Register([](AudioEndPoint::AudioDevicePtr device) { std::wcout << std::endl << device->ID << L" : REMOVED" << std::endl; }); std::wcout << L"Enter the letter Q + Enter to stop the application" << std::endl << "When a device change state or is disconnected you'll be notified" << std::endl << std::endl; auto test = 'a'; while (test != 'q') { do_work(playbackDevices, recordingDevices); std::cin >> test; if(test == 'r') { signInfo->m_signal->Unregister(*signInfo); } } }
