I ended up using VoiceMeeter Banana as my default sound control. It sounds like I was having a similar issue, just getting the Visual from my NDI source but not the audio. But in most cases it would do it once, and remember the number, and provide properly synced audio and video after you play the sample.Ĭlick to expand.Not sure if this is a 100% fix, but I was able to get audio coming from an NDI source on a remote computer running Serato into a Zoom meeting. You could repeat the pattern in the sample video file a few times, to let it calculate an average if the sync delay is varying. The virtualcam/audio device could notice this magic video frame (some never real pattern in the first line) and then look in the sound buffer for the audio spike, and calculate the sync offset. That video file would contain a distinct video image and a distinct audio waveform, and play them together. To do automatic sync, you would provide a short video file to play as a source in OBS. I can install voicemeeter and I think it can do latency, or I can add latency in the OBS advanced audio settings (which one doesn't want to do because that's global and must be turned off if you want to do a recording etc.) But one nice advantage of a simple device that was part of virtualcam is that it could include an automatic synchronizer. Because of my lack of forum posting, I have no clue if this post is in the right place.In followup to this, I calculated my audio as coming about 50ms before the video. Now the question: How do I set up my rig to have all audio come out of my headphones, while excluding the music that will play through the speakers (that will be off so I can't hear them) thus going through the stream so viewers can hear it. and therefore plays all audio my computer makes through both my speakers and headphones. How my sound is set up now: I have default playback device as 'Speakers' which responds to both 3.5mm jacks for some genius reason. I have a AT-2020 microphone, if that helps at all, I have two simple speakers hooked into a single rear 3.5mm green output jack on my motherboard, and then lastly I have my Sony headphones hooked into the front of my computer in another 3.5mm green output jack. When I go to my playback devices I only have 'Speakers' and 'VB Audio Virtual Cable' as the only working audio outputs. I use OBS, Open Broadcaster Software, a lot and would love to have my viewers hear myself, my game, and some nice music. Okay, I don't post on forums much, because I'm usually pretty good at researching through the inter-web, however I'm at a loss for wits with this problem, so I'll get right to the point.
