Problem with ofSoundStream

hi,
i made an app that uses the onboard sound card using the direcshow drivers in windows:

ofSoundStreamSettings settings;
	settings.setApi(ofSoundDevice::Api::MS_DS);
	auto devices = soundStream.getDeviceList(ofSoundDevice::Api::MS_DS);
	settings.setInDevice(devices[4]);
	settings.setInListener(this);
	settings.sampleRate = sampleRate;
	settings.bufferSize = bufferSize;
	settings.numBuffers = 2;
	settings.numInputChannels = 2;
	settings.numOutputChannels = 0;
	soundStream.setup(settings);

the problem is that sometimes i have to run it a few times till it open, the first few times it just crashes without giving any error, and i have no idea why it may be.
i don’t have this problem with all the api, but MS_DS is one of the few that make this (and i need to use this one in this app).
any idea what may be causing the problem?

thank you
