hi i have problem with capture 2 sound device in same time. i have one system with 4 sound card and i want to record sound from 2 sound card in same time. i create 2 directSound device in my program. my problem is when i create two directSoundCaptureBufer and start recording from one device. after stop recording from that device with IDirectSoundCaptureBuffer_Stop(lpdscb); and then i start recording again, streamTofile() calls frequently that means in stop time, events stored and after start recording, all stored events run and streamTofile call frequently unreasonable! if i create only one capturebuffer this problem dont accure and after stop and start again recording start without call streamTofile() unreasonable! this occur independent of device 2 start or stop. some code:

		DWORD dwEvt = MsgWaitForMultipleObjects(
				NUMCAPTUREEVENTS,
				rghEvent,          
				FALSE,             
				INFINITE,          
				QS_ALLINPUT);
	 
		dwEvt -= WAIT_OBJECT_0;

		if (dwEvt < NUMCAPTUREEVENTS) 
		{
			StreamToFile();
		}
 

i debug my program and i know that in stop time, my program dont go inside if(dwEvt < NUMCAPTUREEVENTS) and therefore streamTofile() dont called in stop time.
