C++ (Cpp) AlsaInit Examples

Example #1

File: AlsaSoundStream.cpp Project: Asmodean-/Ishiiruka

bool AlsaSound::Start()
{
	m_thread_status.store(ALSAThreadStatus::RUNNING);
	if (!AlsaInit())
	{
		m_thread_status.store(ALSAThreadStatus::STOPPED);
		return false;
	}

	thread = std::thread(&AlsaSound::SoundLoop, this);
	return true;
}

Example #2

File: AlsaSoundStream.cpp Project: Catnips/dolphin

// Called on audio thread.
void AlsaSound::SoundLoop()
{
	if (!AlsaInit()) {
		thread_data = 2;
		return;
	}
	Common::SetCurrentThreadName("Audio thread - alsa");
	while (!thread_data)
	{
		m_mixer->Mix(reinterpret_cast<short *>(mix_buffer), frames_to_deliver);
		int rc = m_muted ? 1337 : snd_pcm_writei(handle, mix_buffer, frames_to_deliver);
		if (rc == -EPIPE)
		{
			// Underrun
			snd_pcm_prepare(handle);
		}
		else if (rc < 0)
		{
			ERROR_LOG(AUDIO, "writei fail: %s", snd_strerror(rc));
		}
	}
	AlsaShutdown();
	thread_data = 2;
