My setup:
PC running OBS V26.1.1 64Bit
Inputs:
USB Mixer (from church microphones)
IP Cameras (video only thru RTSP and GStreamer. No audio)
Media files (mixture of mp4 video and mp3 audio)
JPG slides
Outputs:
USB Mixer (to church amplifier and speakers)
Epson A/V projector (connected by WiFi)
Facebook Live thru Internet connection (30-50Mbps download, 10-20Mbps upload)
Problem:
Sometimes when I start streaming to FB, audio out from OBS to USB Mixer disappears. We were already playing a scene with audio from a media source and we can hear the audio from USB mixer to church speakers. After we Start Streaming in OBS and hit Go Live in FB, the audio to the USB Mixer suddenly disappears. The OBS mixer display continues to show audio activity but the USB Mixer doesn't. We can still hear audio streamed thru FB, but we could not hear audio coming out of the church speakers thru the USB Mixer. I looked at Sound Settings of Windows and found that there is no sound activity in the USB Mixer. The USB Mixer is the default playback and recording device. Before we went live, everything was OK. This problem doesn't happen all the time. Has anyone encountered this problem before?
