OBS drops sound during livestream

This same issue was reported by someone about 10 months ago and received no replies. Please help those of us that are volunteering to help our nonprofits. Here's the question: Does anyone know why OBS would suddenly drop the sound from an ongoing broadcast? It will be going along fine, then nothing. We also have a Zoom connection going at the same time that still has audio and the separate audio meter on the same computer shows the sound is available. But OBS will just suddenly stop sending it through. Why would that happen?

Depends on how you are connecting/routing audio, your Operating System Audio settings, and your OBS Studio Audio settings

If you have certain plugins, those could be a source of the problem.
in my experience, if no plugin messing with audio, then the typical issue is an overloaded PC. What are you doing for real-time hardware resource utilization monitoring? if nothing (typical scenario), then you are driving blind.

Let's start with pinned post in this forum requesting you post your OBS Studio log from a session where the problem occurred when asking for help
 
We are streaming a church service with input to OBS coming through ATEM Blackmagic sound source. Speakers in the room are working fine, but the streaming audio cuts out when a second singer joins the first or when we try to capture the whole room singing together. The Noise Gate is turned off, and I don't know where to look for any other filter.

Thanks for the response. I was looking for info while I'm at home. When I'm back at the office, I'll get the log and upload it. Thanks again.
 
Here is the OBS log file from the broadcast in question.
The sound dropped out about 9:49 and was out for about 8 minutes.
It dropped out again about 10:18 and was out for about 2 minutes.
Again about 10:50 and was out about 2 minutes.
Can you tell me why this is happening?
 
You have a monster of a PC according to that CPU... but
why 60fps for a House of Worship livestream? would anyone watch your content in slo-motion? I'd think you are wasting bits for extra frames when that bitrate could be used for higher quality video

Bad thing - you have audio devices on different sampling rates... best not to do that, just in case
09:10:07.915: WASAPI: Device 'Line 1/2 (2- M-Audio M-Track Solo and Duo)' [44100 Hz] initialized (source: Mic/Aux)
..snip..
09:10:08.130: WASAPI: Device 'Speakers (Realtek(R) Audio)' [48000 Hz] initialized (source: Desktop Audio)

this is a problem... not sure the cause
09:14:20.572: Max audio buffering reached!
...snip...
09:14:20.592: Source Desktop Audio audio is lagging (over by 194660.71 ms) at max audio buffering. Restarting source audio.

Makes me curious about your Audio software, drivers, etc at Operating System level
Any possible audio coming over a USB link whose Root Hub is overloaded (aor dealing with mix of USB generations and slowed as a result)

09:49:56.042: Device 'Line 1/2 (2- M-Audio M-Track Solo and Duo)' invalidated. Retrying (source: Mic/Aux)
09:49:56.788: WASAPI: Default output device changed
09:49:56.798: Device 'Speakers (Realtek(R) Audio)' invalidated. Retrying (source: Desktop Audio)
09:49:56.868: WASAPI: Default input device changed

I presume the above is your loss of audio? I'd start by looking at Operating System logs to see if anything obvious

What other traffic is on your LAN/WAN link to cause this?
11:53:29.027: Output 'simple_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 1862 (0.3%)
or is this a cellular ISP, or is there a WiFi bridge link, or??
