2.6.2 to 3.0 WSAPI

Someone else just reported that same warning and it turned out, that they destroyed the only sf::Sound instance while still trying to play aduio, which will destroy the audio device likely leading to the given warning.

Make sure your sf::Sound and sf::Music instances exist for as long as you're using them to play audio.

With so much manual memory & lifetime management, it's going to be really hard to tell what is correct and what could cause some lost reference (i.e. memory leak).

If you can rebuild SFML, you could uncomment the // #define MA_DEBUG_OUTPUT line in Miniaudio.cpp which will give you more information on what miniaudio is doing.

Does this work (without that error)?

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>

int main()
{
        sf::SoundBuffer* pSb{};
        sf::Sound* pSd{};

        pSb = new sf::SoundBuffer{};
        if (!pSb->loadFromFile("D:/resources/audio/music/Shiny Toy Guns - You Are The One.ogg"))
                return EXIT_FAILURE;

        pSd = new sf::Sound(*pSb);

        pSd->play();



        sf::RenderWindow window(sf::VideoMode({ 960u, 540u }), "");
        while (window.isOpen())
        {
                while (const auto event{ window.pollEvent() })
                {
                        if (event->is<sf::Event::Closed>())
                                window.close();
                        else if (const auto * keyPressed{ event->getIf<sf::Event::KeyPressed>() })
                        {
                                switch (keyPressed->code)
                                {
                                case sf::Keyboard::Key::Escape:
                                        window.close();
                                        break;
                                }
                        }
                }



                window.clear();
                //window.draw();
                window.display();
        }
}
 

It's based on your code and seems to be what it does.
Obviously, you'd need to insert a filename that is valid for you

... I have added a text output to the sound loading loop.
... the sounds are all present and work after loading during the game.
... the warning comes 3* and only after the first sound:

Sound<V:/VCke/_KKlang/_KKrach/SoundLaden1.ogg>
miniaudio WARNING: [WASAPI] Failed to find suitable device format for device info retrieval.
miniaudio WARNING: [WASAPI] Failed to find suitable device format for device info retrieval.
miniaudio WARNING: [WASAPI] Failed to find suitable device format for device info retrieval.
Sound<V:/VCke/_KKlang/_KKrach/Warnung.ogg>
Sound<V:/VCke/_KKlang/_KKrach/Achtung.ogg>

We lack some information to determine the underlying issue.

I suggest to try Hapax's example code and see if it produces the same error.

Does this work (without that error)?

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>

int main()
{
        sf::SoundBuffer* pSb{};
        sf::Sound* pSd{};

        pSb = new sf::SoundBuffer{};
        if (!pSb->loadFromFile("D:/resources/audio/music/Shiny Toy Guns - You Are The One.ogg"))
                return EXIT_FAILURE;

        pSd = new sf::Sound(*pSb);

        pSd->play();



        sf::RenderWindow window(sf::VideoMode({ 960u, 540u }), "");
        while (window.isOpen())
        {
                while (const auto event{ window.pollEvent() })
                {
                        if (event->is<sf::Event::Closed>())
                                window.close();
                        else if (const auto * keyPressed{ event->getIf<sf::Event::KeyPressed>() })
                        {
                                switch (keyPressed->code)
                                {
                                case sf::Keyboard::Key::Escape:
                                        window.close();
                                        break;
                                }
                        }
                }



                window.clear();
                //window.draw();
                window.display();
        }
}

And otherwise try to enable miniaudio debug information to get more clarity on what's going on:

If you can rebuild SFML, you could uncomment the // #define MA_DEBUG_OUTPUT line in Miniaudio.cpp which will give you more information on what miniaudio is doing.

... I use SFML via LIB and INCLUDE, so I have no access to miniaudio.cpp.
... the current programming with SFML is a Hoppy project to which I have only limited access at the moment.
... since everything works despite the warning, I'm happy with it at the moment.
... thanks for the information and the help.
