How to call thread with a public member function from another class as argument

Question

I already checked Start thread with member function and similar posts, and followed the instructions, but I get this error message:

'std::invoke': no matching overloaded function found

SerialPort.h

#include <array>
#include <string>

class AudioClass
{
public:
    void playAudio(std::array<std::string, 11> turretDetectionWavFiles, std::array<std::string, 6> turretActivationWavFiles,
        std::array<std::string, 4> turretSearchingWavFiles, std::array<std::string, 16> turretPowerDownWavFiles, std::array<std::string, 3> turretAttackWavFiles, std::array<std::string, 11> turretMovedWavFiles,
        std::array<std::string, 12> turretDie);
};

                            "turret_tipped_4", "turret_tipped_5", "turret_tipped_6", "die.wav" }; 


void AudioClass::playAudio(std::array<std::string, 11> turretDetectionWavFiles, std::array<std::string, 6> turretActivationWavFiles,
    std::array<std::string, 4> turretSearchingWavFiles, std::array<std::string, 16> turretPowerDownWavFiles, std::array<std::string, 3> turretAttackWavFiles, std::array<std::string, 11> turretMovedWavFiles,
    std::array<std::string, 12> turretDie)
{
    //do something
}

void exampleReceiveData()
{
    std::thread t(AudioClass::playAudio, (turretDetectionWavFiles, turretActivationWavFiles, turretSearchingWavFiles, turretPowerDownWavFiles, turretAttackWavFiles, turretMovedWavFiles, turretDie));
}

int main()
{
    exampleReceiveData();
}

I also tried this way, and got the same error:

std::thread t(&AudioClass::playAudio, AudioClass());

The this pointer needs to be passed as the 1st argument:

void exampleReceiveData(void)
{
    AudioClass ac;    
    std::thread t(&AudioClass::playAudio, &ac, turretDetectionWavFiles, 
                  turretActivationWavFiles, turretSearchingWavFiles, 
                  turretPowerDownWavFiles, turretAttackWavFiles, 
                  turretMovedWavFiles, turretDie);
    t.join();
}
