To hear a prerecorded clip in the church room while OBS sends the programme to YouTube, choose a local Monitoring Device in OBS and set the clip’s monitoring mode according to the route OBS already captures. The device you hear through and the mix viewers receive are related, but they are not the same setting.
First identify the actual output you want the team to use, then check whether OBS also captures the computer’s playback through Desktop Audio or another source. Do not assume that selecting headphones, speakers or an interface automatically determines what viewers hear; verify the two paths separately with a test recording.
Choose the room listening device
Start with the practical question: where should the volunteer hear the clip? It may be the computer’s headphone output, speakers, or a headphone output on an audio interface. The appropriate choice depends on the room’s existing connections and how the team listens during a service. There is no universal device name or preferred output for every church.
Check the physical route before opening OBS. Note which socket or connected device the headphones or speakers use, and play ordinary computer audio through it. If more than one output is available, decide which one should be used for monitoring and keep the choice consistent during rehearsal. A headphone output is often useful because it lets an operator listen without sending the clip through the room loudspeakers, but it is not a requirement.
The name displayed by OBS comes from the computer and connected hardware. It may not be an obvious description of the socket you have in mind. Do not guess from a familiar brand name or select the first item that sounds plausible. Confirm the output by selecting it, playing a short piece of audio, and listening at the intended headphones or speakers. If the device list changes after connecting an interface or restarting the computer, check it again.
Keep the intended listening path distinct from the programme mix. For example, you may want a volunteer to monitor quietly on headphones while the stream receives the clip at a suitable level. Moving a cable or changing the computer’s default output can affect playback, but it does not by itself prove that OBS is receiving the right signal. If you are still planning the broader prerecorded workflow, the guide to connecting OBS to YouTube Live for a prerecorded stream covers the separate broadcast setup.
Set the OBS Monitoring Device
In OBS Studio, open Settings > Audio and find Monitoring Device. Select the output that should play the monitored audio locally. The precise label depends on the computer and its connected outputs, so use the listening test from the previous section rather than relying on an assumed name.
After changing the selection, apply the settings and test the route with a source that you can safely play. Listen through the intended device. If the sound still comes from a different output, inspect the device selection and the computer’s current audio configuration. Some systems have separate playback endpoints for speakers, a headset, or an interface; choosing one endpoint does not necessarily redirect every other sound made by the computer.
The Monitoring Device setting answers, “Where does OBS play audio that is being monitored?” It does not answer, “Which audio reaches YouTube?” OBS handles source output and local monitoring with different controls. A source might be sent to the programme mix without being heard through the selected local monitor, or be heard locally without being part of OBS output. That distinction is the centre of this setup.
OBS’s Audio Mixer Guide describes checking audio both early in the device chain and again through OBS Audio Monitoring. Use both checks: first confirm the chosen physical output can be heard, then confirm the sound reaches OBS as intended. A meter moving in OBS is useful evidence of signal, but it does not tell you whether the selected headphones are audible or whether the final recording contains the sound only once.
Enable monitoring for the prerecorded source
With the clip playing in the scene you plan to use, open Advanced Audio Properties from the mixer gear or the Edit menu. Find the audio source associated with the prerecorded video, often a Media Source, and inspect its monitoring control. Monitoring behaviour is configured per source, so setting the Monitoring Device alone will not make every source audible locally.
Choose the mode by tracing the signal. If OBS is not capturing the computer’s playback output elsewhere and the clip must be heard locally and sent to viewers, set the source to Monitor and Output. This sends that source to the selected monitoring device as well as OBS output. Confirm that the clip is audible locally and that a test recording includes it.
If OBS captures the same playback through Desktop Audio and the clip also needs to be heard locally, Monitor Only may be appropriate for the Media Source. In that arrangement, the Media Source itself is monitored locally, while the captured Desktop Audio path carries the sound into OBS output. Check that this captured path appears once in the test recording. Monitor Only does not send that Media Source to OBS output; it only works for viewers if a separate captured path is carrying the clip.
If the source should be present in the recording or stream but not heard through the local monitor, use Monitor Off and check the result. The right choice depends on your signal path, not on whether a church is using a particular type of service or video. OBS’s Video Call Streaming Tutorial explains the distinctions among the monitoring modes; your own test remains necessary because the tutorial cannot know which outputs your computer captures.
Check the source’s monitoring mode
Before changing a mode, draw a simple path for the clip. It may enter OBS as a Media Source, then go to OBS output. Separately, OBS can monitor it to the selected local device. In some setups, the computer’s playback output is also captured as Desktop Audio or through an audio-capture source. If that happens, there can be two routes from one clip into the programme mix.
| What OBS captures | Media Source mode to consider | What the test should show |
|---|---|---|
| No separate capture of the playback output; the clip should be local and in OBS output | Monitor and Output | Audible on the chosen local output and present once in the recording |
| Desktop Audio or another source captures the same playback; the clip also needs local monitoring | Monitor Only for the Media Source | Audible locally, with the captured route present once in the recording |
| The clip should be in OBS output but not locally monitored | Monitor Off | Absent from local monitoring and present in the recording |
These are routing examples, not universal prescriptions. The second row only works if the separate capture really carries the playback to OBS. Conversely, Monitor and Output does not always create a duplicate: it becomes a concern when another OBS path is also sending that same sound to output. Confirm the signal flow instead of switching modes repeatedly and hoping the result improves.
A useful way to reason about it is to ask, for each path, whether it feeds the room, OBS output, or both. The local monitor route is for the operator’s listening. The OBS output route is what the recording or live programme can contain. Desktop Audio capture is another input route; it is not merely a synonym for local monitoring. If you are unsure whether a source is captured twice, temporarily mute or disable one candidate path during a controlled test, then restore the intended settings and test the full arrangement again.
If your service uses a playlist or a long-running prerecorded sequence, audio checks belong alongside the visual and broadcast checks. The guide to setting up a playlist for a 24/7 YouTube bhajan stream discusses playlist operation; it does not replace a source-by-source OBS audio check. Treat a clip transition as another point to listen and watch the mixer, particularly if different files have different audio characteristics.
Test local playback and stream audio separately
Run a short rehearsal with the actual scene and clip, not just a tone or an unrelated desktop sound. Confirm that the intended headphones or speakers are audible. Watch the relevant mixer meter while the clip plays, and check for mute states or a level that reaches the meter’s clipping indication. A moving meter confirms activity in that OBS source; listening confirms the local output is working.
Then make a short OBS recording using the ordinary service settings. Play the resulting file back and listen for silence, missing speech or music, and doubled playback. This tests the recorded programme path, which is more informative than assuming that a signal heard locally must also be present in the programme. If the recording sounds right but live monitoring does not, revisit the local device route. If local sound is clear but the recording is absent or doubled, revisit the OBS output paths.
For a live service, also check the programme as a viewer would hear it, using a suitable monitoring method that does not feed the stream audio back into the room mix. Keep the stream mix in view while the clip plays. If you change a fader, mute, source mode or capture setting, make another short recording: one successful test does not validate a later configuration change.
OBS recommends listening at more than one point in the chain and recording under normal conditions before relying on the setup. Its mixer guidance is a useful checklist for the meter, device and monitoring checks. For a channel expected to remain on for long periods, plan who will notice a silent or doubled clip and how they will verify the next transition. If the wider challenge is keeping a prerecorded broadcast running when a local computer is not attended, StreamNeo removes the need to leave that computer operating by turning an uploaded video into a YouTube live stream, while the audio still needs to be checked in the file and channel workflow.
A rehearsal note can make repeat checks easier for volunteers. Record the chosen device exactly as OBS displays it, the source name, its monitoring mode, whether Desktop Audio or another capture path is enabled, and the result of the test recording. Do not write only “headphones on” or “audio fine”: those notes do not reveal which route was tested. Recheck after a device is unplugged, a scene is rebuilt, or a computer’s audio configuration changes.
Troubleshoot missing or doubled audio
If the room cannot hear the clip, first check that the correct output is selected as the Monitoring Device and that the headphones or speakers work with another known sound. Then check that the clip’s audio source is active, unmuted, and configured for a monitoring mode that sends audio locally. A source set to Monitor Off will not be heard through OBS monitoring. Also check whether the clip itself has an audible soundtrack and whether playback has started.
If the room hears the clip but the recording is silent, identify which path OBS is meant to use for output. Monitor Only excludes that Media Source from OBS output, so it cannot carry the clip to viewers by itself. If Desktop Audio is meant to carry it, confirm that the desktop capture is enabled and its meter responds. Otherwise, consider Monitor and Output and test whether that introduces a second route.
If the recording contains doubled or echoing audio, look for two OBS paths carrying the same playback: for example, the Media Source on Monitor and Output and the same computer output captured as Desktop Audio. Change one route at a time, record again, and listen. Do not assume that turning the local monitor down will fix a duplicate in the programme; a monitor level and an OBS output path do different jobs.
Also check for duplicate device capture. OBS warns that configuring a device globally and adding that same device again as an Audio Input or Output Capture source can create echo. Its Audio Sources guidance explains this risk. Review both global audio devices and scene sources rather than removing a source at random, then keep the route that is needed and retest.
If sound is present but too quiet, too loud or distorted, follow it through the chain: the clip’s level, any computer playback level, the OBS source fader, and the recording. Change one control at a time and listen back. Avoid trying to solve every level issue by increasing the stream output; that can leave the local monitor misleading or push the captured signal into clipping. For video delivery issues separate from audio routing, the guide to fixing dropped frames when streaming prerecorded video to YouTube Live covers a different part of the chain.
For a final pre-service check, play the clip in its intended scene, verify the local device by listening, watch the relevant meters, record a sample, and listen to the file. If anything changes after that test, repeat it. A written route and a repeatable check are more dependable than relying on a volunteer remembering which dropdown worked last week.

FAQ
Does Monitor Only mean the clip will still reach YouTube?
Not by itself. Monitor Only sends that source to local monitoring but not to OBS output; the clip reaches viewers only if another route, such as Desktop Audio capture, carries it into the programme. Confirm the route in a test recording.
Should I use Monitor and Output for every prerecorded video?
No. Use it when the source needs to be heard locally and sent to OBS output, and no other captured path is also carrying the same playback. If OBS captures that playback separately, account for both paths and test for duplication.
Why can I hear the clip but see no activity in the OBS meter?
You may be hearing computer playback outside the OBS source you are watching, while the source intended for the stream is muted, inactive or routed differently. Check which source is producing the sound and watch its meter during playback, then verify the recording rather than relying on the room sound alone.
Does the Monitoring Device setting decide what viewers hear?
No. It selects where OBS plays monitored audio locally. The source’s monitoring mode and any captured inputs determine what enters OBS output, so listen locally and check a recording as separate tests.
