The only workaround is to restart OBS every 10 minutes. Using different apps to record the test video.playing with (muting/unmuting etc) various settings in OBS, MacOS's MIDI audio device panel and MacOS's Sound panel.The following things do not solve the problem, once it manifests: The default scene is the only one there, and is empty. No video inputs or other audio sources configured in OBS. No other CPU/RAM/GPU intensive programs are running on the Mac. I'm using a Trust USB microphone as a source. Observe that there is now a delay between lips and audio. Wait 20-30' (Photo Booth doesn't need to be open).Watching the recorded video, observe your lips and note that there is no or minimal delay between audio and video. Say "test" and stop recording after a couple seconds. Record a video with the webcam showing your face.Hold Option and click on the audio icon at the top system bar, select BlackHole as the input device.In the audio mixer panel (lower center), click the cog of the mic source > Advanced audio properties > next to Mic/aux, under audio monitoring, select monitor & output.
In obs, settings > audio > Mic/Aux audio: select a microphone.Install OBS and either BlackHole ( brew install blackhole) or VB-Cable.(Log attached in following comment, to keep this field short) Steps to Reproduce Over time this increases, reaching more than 1 second lag after 90 minutes of having OBS running. After a few minutes (as low as 10), there is a noticeable delay added to the audio stream that is output to the monitor. When I first start OBS, the audio is delivered to the monitor with minimal lag.
OBS Studio version: 26.0.2 Expected BehaviorĪudio output of OBS should be delivered with minimal lag/latency/delay to the audio monitor output Current Behavior
