Hi, I have purchased an 'East Cap' USB port to plug into my old Sony Digital 8 Cam to capture old video. A friend suggested I use the OBS software, which has been great, however when I play back the digitized recording, the audio comes across Ok, but then after about 20 seconds the audio is recorded again in delay. So there are two audio recording running separately . I have connected the USB hardware with all three Red, Yellow and White jacks. How can I stop the second audio stream from being recorded?
