Hi, I'm new guy on audio driver, and learn sample MSVAD in DDK. I wrote a vitural mic driver based on MSVAD, and modify CopyFrom function. The data is from a wave file or a noise produced myself. But the sound captured by this virtual mic is discontinuous. The capture graph like this: MSVAD ---> speaker But when I use it to capture to the file, the wave file's sound is normal. (MSVAD ---> wavedest ---> file writer). Why the MSVAD capture sound is discontinuous? It seems that some time the speaker is starved and has to fill the data by zero. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
