If you need to hear a playlist locally while it continues to reach your YouTube stream, set its OBS monitoring mode to send audio to both the monitoring device and the output. Then check the source meter and listen in OBS; the monitoring setting does not create the loop or guarantee uninterrupted streaming.
A harsh sound can come from two different problems: the signal may be clipping throughout playback, or a brief click may occur exactly where the file repeats. Lowering the level can help with clipping, but a limiter is not a remedy for a loop-boundary click. Diagnose when and where the sound occurs before changing settings.
First identify the sound: clipping or a loop-seam click
Clipping happens when the audio signal exceeds the available level. You may hear it on loud notes, percussion hits, or busy passages, and it can recur wherever the source is loud. In OBS, watch the audio source’s meter while that passage plays. The OBS Audio Mixer Guide describes the meter as a way to view source level and identifies its red zone as near clipping. A meter is useful evidence, but listening matters too: check the actual stream output path rather than assuming the display alone tells the whole story.
A loop-seam click has a different pattern. It is a short tick, pop, or abrupt change that recurs at the moment the file reaches its end and starts again. If the rest of the track sounds clean and the noise is tied to the repeat point, do not treat it as general overload. The file may have an abrupt waveform or room-tone change at its boundaries, or the player may transition between the end and beginning in a way that is audible.
For example, if a devotional recording sounds clear for most of its length but ticks once at every restart, focus on the file’s start and end. If the loud chorus distorts each time it plays, investigate its level and peaks. Both faults can happen in one file, so test them separately rather than assuming a single adjustment will fix both.
This distinction is especially useful in a long-running channel, where a small defect repeats all night. A brief transient can be easy to miss while you monitor a short sample, so note the playback position when it occurs and listen through a complete repeat. For broader choices about players and loop workflows, see software for looping prerecorded videos on YouTube Live. That choice is separate from OBS’s local monitoring controls.
Set up a single file as a looping Media Source
For a single video that you want OBS to repeat, add it as a Media Source and check the source’s loop option in its properties. The exact arrangement of controls can depend on the OBS version, so verify the setting in the installed version rather than relying on a screenshot from another release. The aim is simply to have the media source play again after reaching the end.
Looping and monitoring solve separate problems. The loop control determines whether the file repeats; audio monitoring determines whether you hear that source through a selected local device. A source can continue to reach stream output without local monitoring, and you can monitor a source without having created a reliable playlist workflow. Confirm both behaviours independently.
If the source is meant to remain audible to viewers, check that it is not muted in the mixer and that its output is active. Later, use Advanced Audio Properties to choose the monitoring mode that also leaves the signal in output. You can first test a short passage, but a short test will not reveal a click that occurs only at the repeat boundary. Let the file reach its end and restart before considering the seam checked.
A Media Source is a straightforward fit when the channel is built around one prepared file. If you need several files in sequence, playlist behaviour and transitions are a different setup question. The guide to setting up a 24/7 YouTube music stream with OBS covers the wider OBS workflow; use it for the overall channel arrangement, not as a substitute for listening to this source’s repeat point.
Enable Loop Playlist for VLC Video
If you use VLC Video Source for a sequence of files, enable its Loop Playlist option in the source properties when you want the playlist to repeat. This setting is about repeating the playlist, not about smoothing the audio between one file and the next. Listen at every transition that matters, particularly the point where the final item returns to the first.
Do not assume that a playlist loop and a single-file loop behave identically at the boundary. A single file has its own end and beginning; a playlist may also involve a change of file. Either can expose a change in level, background noise, ambience, or musical timing. If a transition is meant to sound continuous, prepare the material and test the actual transition rather than relying on the name of a loop option.
If the source behaves differently after a restart or when the computer has been running for a long time, log what happened and check the media path and source configuration. This is not a reason to change the monitoring mode at random: first establish whether the source is playing, whether its meter is moving, and whether the sound itself is present at the transition. A playlist file-path troubleshooting guide concerns a different playback method, but it illustrates why file access and audio monitoring should be treated as separate checks.
Choose the monitoring mode and destination
In the OBS mixer, open Advanced Audio Properties for the playlist’s audio source. The monitoring control has modes for no local monitoring, local monitoring only, and monitoring while retaining output. The OBS English locale currently labels these Monitor Off, Monitor Only (mute output), and Monitoring Enabled; labels and controls can vary by version. Read the wording shown in your own installation.
| What you need | Monitoring choice | What to verify |
|---|---|---|
| Audio to stream, not played locally by OBS | Monitor Off | Source remains unmuted and reaches output |
| Local listening without sending that source to output | Monitor Only (mute output) | This is not appropriate if viewers need the source |
| Local listening and audio in output | Monitoring Enabled or the equivalent label | Listen locally and confirm the source remains in the mix |
For a stream that should include the playlist, choose the mode that monitors and keeps the source in output. “Monitor Only” is explicitly described as muting output in the OBS locale labels, so it is the wrong choice if you expect that source to remain on the stream. OBS’s Audio Mixer Guide explains that the monitor control plays the source through the monitoring device configured in Settings.
Next, open OBS audio settings and select the intended monitoring device. This might be headphones or another playback device you can hear clearly. Wired headphones are an optional practical choice if you want to listen without room speakers feeding back into a microphone; they are not a requirement, and no particular model is needed for the setting to work.
Check the routing before monitoring for an extended period. If the same playback device is also captured by OBS as desktop or application audio, the signal may re-enter the mix through a second path. That can sound like echo, doubling, or a hollow version of the original. A separate output device or carefully configured virtual audio route may help, but it adds configuration to check. OBS community discussions describe this kind of duplicate-path problem; see the device-routing discussion if the source reaches viewers but not your headphones, or if you hear a duplicate.
Check whether the source is truly clipping
Play a passage that you already know is loud, and watch the playlist source meter in OBS. The mixer guide notes that stereo sources have separate left and right meters, so look at both sides where applicable. If only one channel is consistently higher, investigate whether the file itself is imbalanced before applying a broad adjustment to every source in the scene.
A red meter indication is a warning to investigate, not a diagnosis of every click you hear. Observe when it appears. If it coincides with loud passages and distortion, level reduction is a sensible first test. If it appears nowhere near the repeat point but the click always occurs at the boundary, the likely issue is different. Conversely, an abrupt boundary can make a click without a sustained red meter reading.
Listen to the audio as early in the chain as practical, then listen through OBS. The Mixer Guide recommends listening to the signal and recording a normal session for playback before going live. A short local recording gives you a way to hear what the OBS mix actually contains, rather than only judging the source file in a separate player. Include the loud passage and the repeat boundary in that check.
Avoid changing the global output level first if the problem belongs to only one media source. A global adjustment can make other scenes or microphones too quiet while leaving the defect’s cause untouched. Keep a note of the starting level and change one control at a time, so you can tell whether the result came from the source fader, a filter, a different monitoring route, or an edited file.
Reduce source level and use a Limiter for peaks
If the source is genuinely too hot, lower its level in OBS and listen again to the loudest section. Keep enough level for the material to remain audible beside other sources, but do not compensate by pushing the final output higher without checking the whole mix. A quiet source and an overloaded mix are different problems; adjust the path that is actually producing the excessive level.
A Limiter can be useful as a peak-control measure on the source or mix when occasional peaks rise above the level you want. In OBS, add it as an audio filter and place it after gain-raising or other level-changing filters if you are using them, so it can respond to the resulting signal. Then listen and record a test. A limiter can alter how peaks sound, and aggressive settings may make music or ambience feel constrained, so use it as a control to assess, not a reason to stop checking.
The key boundary is worth stating plainly: a Limiter is not a fix for a click at the loop seam. It acts on signal level; it does not edit the start and end of the source into a smooth transition. If a brief transient occurs at every repeat, turning down the entire programme or placing a limiter in the chain may make the click quieter, but it does not address why that transient is there. Return to the source file and transition when the fault is boundary-specific.
For a nonstop channel, avoid judging the filter only on the first few seconds. Play the loudest content, let the limiter encounter a peak, then listen to the repeat boundary separately. If a recording sounds clean before OBS but distorted after the mix, review OBS levels and filters. If it is already distorted in a direct file player, repair or replace the source before expecting OBS controls to restore it.
Investigate noise at the repeat boundary
When the sound is tied to the repeat point, start by listening to the end and beginning of the file in an editor or media player that lets you move precisely around those points. Check whether the final audio abruptly stops while the opening begins at a different waveform level, or whether background ambience changes suddenly. You do not need to assume that every loop can be made seamless; some material has a natural ending that is not suited to a hard repeat.
If the content allows it, prepare a version whose opening and ending are more compatible, or use an intentional transition in the editing workflow. For music, this may mean selecting a section that can repeat musically; for room tone or ambience, it may mean avoiding an abrupt change in the underlying sound. Any crossfade or edit should be reviewed for timing and content before it becomes the channel’s source. OBS’s loop option alone does not create a seamless audio transition.
Compare a direct playback of the prepared file with playback through OBS. If the click is present in both, investigate the file or the edit. If it appears only in OBS, check the source configuration, transition behaviour, filters, and whether another captured audio path is overlapping the same sound. Temporarily monitor one source at a time to isolate the path, then restore the intended mix and recheck it.
Do not try to solve every boundary fault by lowering the entire stream. That can make speech, devotional singing, or low-level ambience harder to hear while leaving the abrupt waveform change in place. A useful record is the timestamp or playback position, the source involved, whether the meter spikes, and whether the same point clicks in direct playback. Those observations make the next edit or routing change more deliberate.
Test the full playback and meter path
Before relying on a long-running setup, run a test that includes the parts that can fail differently: ordinary content, the loudest passage, and at least one complete repeat. Watch the relevant source meter, listen through the configured monitoring device, and make a local OBS recording to review. If the source has multiple channels, listen for imbalance as well as distortion; OBS’s mixer guide notes that left and right channels are represented separately for stereo sources.
Confirm the output path in a private or otherwise appropriate test before treating local headphones as proof of what viewers hear. Monitoring is a local cue; it does not demonstrate that YouTube is receiving the same signal or that the live session will stay connected. If local sound is correct but the stream output is absent, revisit mute state and monitoring mode. If viewers hear audio but you do not, revisit the selected monitoring device. For the distinction between a local setup and a whole-channel workflow, see how to start a 24/7 devotional podcast stream in India.
Keep notes of the source, mode, device, and any filters you changed. If the problem returns after a scene or device change, those notes help identify what changed without rebuilding the entire mix. A long-running channel also has continuity concerns beyond audio: monitoring settings do not prevent a process or connection from stopping. Treat audio quality and stream continuity as separate checks, and do not infer that a clean test guarantees a later session will remain live.

FAQ
Which OBS monitoring setting lets me hear the playlist and keep it on stream?
Choose the mode that monitors the source and keeps it in output, labelled Monitoring Enabled in the current English locale. Confirm the exact wording in your OBS version, then check that the source is not muted and remains audible in a test recording.
Why can I hear the source on YouTube but not in my headphones?
The source may be reaching stream output while OBS is configured to monitor through a different or unavailable device. Select the intended monitoring device in OBS audio settings and check the device’s volume and connection. The OBS community has a discussion about this local-monitoring problem and device selection at Listen to video in OBS while streaming?.
Will a Limiter remove a click when the playlist repeats?
No. A limiter can control peaks, but it does not make the file’s end and beginning meet smoothly. If the click occurs at each repeat, compare direct playback with OBS and inspect or edit the source boundary.
Does enabling monitoring make a 24/7 stream uninterrupted?
No. Monitoring controls whether OBS plays the source locally, and the loop setting controls repetition. Neither guarantees that a broadcast, computer, or connection will stay active; test the complete setup and check continuity separately.
