A 24/7 YouTube radio stream can go silent between playlist files even when the playlist is set to loop. Looping tells the playback source to start again after it runs out of media; it does not guarantee a gapless handoff between files.
Start by identifying the source in OBS, then watch the transition in the preview and audio meters. If the next file starts locally, follow the signal through the programme output and a test stream before treating the silence as a YouTube problem.
Identify the source that plays your files
In OBS, check the Sources list in the scene that is actually live. A playlist may be playing through a VLC Video source, while a single repeating video may use a Media Source. These have different controls, so first establish which source owns the audio you expect to hear.
Select the source and inspect its properties. A Media Source points to one media file. A VLC Video source has a playlist of files and can play them in order; it relies on VLC being installed. OBS notes that 64-bit OBS needs 64-bit VLC. If VLC Video is missing or does not play media, check that dependency rather than changing YouTube settings.
Also confirm that the source is present in the scene used for the broadcast and is not hidden, muted, stopped or paused. In OBS, visibility and playback are separate matters: hiding a source can affect whether it plays, depending on its source behaviour and settings. A playlist that works in a test scene but is absent from the live scene cannot provide its audio to the programme output.
If you use an ordered radio rotation, check that the playlist contains the intended files and that shuffle is not enabled. Shuffle is useful for variety, but it makes a transition test harder to reproduce. For a devotional channel, for example, keep a short test playlist in a known order so you can tell whether the expected bhajan really starts after the preceding track.
The distinction matters when you diagnose a quiet interval. A playlist that has finished and is waiting to loop is not the same failure as a file that started but has an empty opening, or a source that is no longer audible in the scene. Make a note of the source type and current order before changing anything; otherwise, several simultaneous edits can obscure the cause.
Set the loop control for that source
For a single file that should repeat, open the Media Source properties and enable Loop. That setting repeats the one file. For a collection of files in a VLC Video source, enable Loop Playlist. OBS describes this control as specifying whether the source should restart after it has run out of media files. It is a restart-at-completion behaviour, not a promise that two different files will join without an audible gap.
The OBS media-source documentation describes the Media Source and VLC Video controls. Use the one that matches your source rather than searching for a global OBS loop switch. If your playlist should return to its first item after the last, Loop Playlist is the relevant control. If you want a single file to repeat, use Media Source Loop instead.
After changing the setting, check the whole path once: apply the properties, return to the scene, and verify that the source is active. Then allow the current file to finish and watch what happens. If you are testing in an existing broadcast, avoid making an unplanned change that could interrupt a real audience; use a private or unlisted test stream where possible.
Loop settings answer what the source should do after it runs out of media. They do not repair an incorrectly ordered list, remove silence encoded at the end of one file, or make differently encoded material transition seamlessly. Treat the setting as the first configuration check, not as proof that the output is continuous.
If your stream freezes on the last frame rather than going quiet, that points to a related but different symptom. The checks in the OBS one-frame freeze guide may help separate a stalled visual source from an audio boundary problem.
Test the exact file boundary in OBS
Do not judge the handoff only by whether the playlist eventually advances. Test the end of one file followed immediately by the start of the next, using the same files and source settings intended for the live channel. Listen to the result, and watch the OBS preview to confirm the expected next item begins.
A practical test can use a short representative copy of the playlist. Start near the end of the first item, let it complete, and keep listening through the opening of the next. Check both sides of the boundary: the tail of the first file may contain silence, and the next file may have a quiet lead-in before its audio begins. A moment that looks like a loop delay may be present in the media itself.
Check that the second item really starts. If the preview remains on the first image or the playlist does not advance, inspect the VLC Video playlist and source status. If the picture advances but the audio disappears, investigate the audio path as well as the files. A visual change alone does not establish that the next file has an audible soundtrack.
For music files prepared from different sources, compare their beginnings and endings in a media player or audio editor if you have one. You are looking for intentional content, not a particular waveform shape: an intro, a fade, a quiet spoken prayer, or a deliberate pause may be part of the programme. Do not cut those out simply to make the meter move sooner. If the quiet section is unwanted, edit a copy and retest it before replacing the live file.
Repeat the boundary test after any change to the playlist, file exports or OBS source. A transition that worked between two tracks does not demonstrate that every pair in a large rotation behaves the same way. You do not need to inspect every hour of a long schedule in one sitting, but test representative boundaries, especially where file formats, recording levels or editing methods differ.
Follow the sound through meters and output
Watch the OBS audio mixer while the first file ends and the next begins. If the relevant meter falls to silence and stays there, the missing signal is at or before that mixer input. Check whether the source is muted, whether its audio is enabled, and whether the next file contains sound at that point. If the meter moves through the boundary, OBS is receiving audio, but you still need to verify that the programme output and stream carry it.
The mixer can show activity from more than one source. Identify which meter belongs to the playlist, and avoid assuming that desktop audio or a microphone is the track you want. For a music-only broadcast, an unrelated input might keep a meter moving while the playlist itself is silent. Conversely, a quiet recording may produce only small movements; listen as well as watching the display.
Monitor the OBS programme output, not just the preview window. The preview is useful for checking which visual item is active, but it is not a substitute for listening to the broadcast output. Use headphones or a separate playback device if practical, and check that you are monitoring the intended programme mix rather than a local source in isolation.
If the playlist meter drops, check source properties and the media boundary first. If it keeps moving but the programme output is quiet, review OBS audio routing, mute states and the active scene. If the programme output sounds right but a test stream is silent, the issue is further along the chain: encoder audio configuration, stream output or delivery should be examined next.
This is also where a checklist for OBS encoder initialisation problems can be useful if the wider output is failing, though encoder initialisation errors are not the same thing as a gap between playlist files. Keep the diagnosis tied to the symptom: an encoder problem may affect the stream as a whole, while a boundary-specific silence often begins with playback or the media itself.
A private or unlisted test stream lets you check the encoded result without asking viewers to report what they hear. Listen from a separate device or browser if you can. Monitoring the same computer that produces the stream may conceal local routing or playback differences. Keep the test long enough to include the transition you are investigating.
Check the YouTube stream health after local checks
YouTube stream health is useful for finding ingestion or delivery trouble, but it does not control how OBS hands one file to another. First confirm that the file advances, the relevant OBS meter moves, and the programme output contains the expected audio. Then compare those observations with the test stream and YouTube’s health information.
YouTube’s encoder settings and live-stream guidance recommends testing before going live and monitoring stream health. Use a test that resembles your actual broadcast, including the audio path and representative media. If the local programme output is already silent at the boundary, a healthy ingestion report will not repair the source. If local output sounds normal but the test stream does not, the platform-side report and encoder configuration become more relevant.
Watch for a difference between a brief silence that recurs at file boundaries and a stream-wide interruption. A boundary-only symptom points you back towards file contents, source behaviour or routing that changes with the item. A broad loss of audio, unstable stream or encoder warning calls for a wider output check. Record what you hear and what OBS and YouTube report at the same time; that makes it easier to distinguish one failure from another.
Do not switch ingest protocols as the first response to a playlist gap. YouTube’s HLS setup guidance covers requirements for HLS ingestion, which is a separate delivery configuration. Changing that path adds work and does not remove silence already present in a media file or created at a local source handoff. Consider protocol-specific guidance only when your stream setup actually uses that protocol and the evidence points to ingestion.
For a stream that also disconnects or fails to remain live, investigate resilience separately from playback. The article on keeping a YouTube channel live all day discusses the broader operating choices. A process restart can recover an encoder that has exited or stopped responding; it cannot make a badly configured playlist continue correctly at a file boundary.
Adjust the files or the playback workflow
If OBS advances correctly but you can hear a pause, inspect the files before changing the streaming chain. Listen to the final portion of the outgoing file and the first portion of the incoming one. Remove accidental leading or trailing silence from copies, or re-export material with consistent, deliberate transitions. Keep a clean original so you can reverse an edit if it changes the intended programme.
Different recordings may have different sample rates, channel layouts, loudness and codec settings. Those differences are reasons to test, not proof of a particular cause. If the transition behaves inconsistently, create two test exports with compatible properties and compare them through the same OBS source. Change one thing at a time: otherwise, you will not know whether the improvement came from the file edit, source setting or audio routing.
A crossfade can conceal a small pause only when it is suitable for the content and the playback workflow supports it. It may be wrong for spoken introductions, prayer recitations or a news bulletin where one item should end cleanly before another begins. Do not apply fades automatically to every item. Decide whether the intended sequence calls for a pause, a direct cut or an overlap, then prepare the files accordingly.
If this is a radio-style channel rather than a playlist of visual programmes, consider preparing a continuous programme file or a set of carefully aligned segments. That reduces the number of boundaries the player has to manage, but makes replacement and scheduling less flexible. With separate files, you can update one track; with a longer render, you must regenerate or replace a larger piece when the programme changes.
The playback method also affects the work you carry. OBS with VLC offers direct control over local files, but the computer, power, software and internet connection need to remain available. An FFmpeg setup on a rented machine can run without a desktop session, but requires command-line configuration and someone to monitor it. Cloud playout can remove the need to keep your home computer switched on; assess the service’s actual workflow and terms rather than assuming it fixes poorly prepared audio.
Where the recurring pain is leaving a personal computer running, StreamNeo lets you upload a video and provide the YouTube stream key so the broadcast can continue with your computer off. That addresses the need to keep a local machine on; it does not make source-file gaps inaudible, so test and prepare the boundary before relying on any playback workflow.
Choose an approach by asking what you need to control and what you can maintain. If you already have a stable OBS setup and want to edit the playlist directly, local playback may be simplest. If you can manage a headless command-line process, a VPS gives you a different kind of control with more operational upkeep. If avoiding a computer at home matters more than editing a playlist live, investigate cloud playout and confirm that its supported content and controls suit your channel.
| Playback approach | What you control | What still needs attention |
|---|---|---|
| OBS with VLC on a local computer | Local playlist order, OBS scenes and source properties | Computer, power, network, VLC and file-boundary testing |
| FFmpeg on a VPS | A scripted playback and restart workflow | Command-line setup, monitoring, file preparation and service recovery |
| Cloud playout | Upload and channel-level playback without keeping your own computer on | Service terms, available controls and the quality of the uploaded media |
No approach removes the need to validate the audio. A restart policy is useful when a playback or encoder process has stopped; it is not a gapless-playback control. Likewise, moving a file to another machine does not remove silence that has been rendered into its start or end.

FAQ
Does Loop Playlist make two files join without a gap?
No. It tells the VLC Video source to restart after it has run out of media files, but OBS does not promise a gapless handoff between different files. Test the actual pair of files in OBS and listen to the programme output.
Should I use Media Source Loop or Loop Playlist?
Use Media Source Loop when you want one file to repeat. Use Loop Playlist with a VLC Video source when you want an ordered list of files to start again after the list ends. Confirm the source type before changing the setting.
The OBS meter moves, but YouTube viewers hear silence. What should I check?
Listen to the OBS programme output and a private or unlisted test stream, then compare them with YouTube’s stream-health information. If the programme output is audible but the test stream is not, check encoder audio configuration and delivery rather than editing files immediately.
Will changing YouTube settings remove silence inside a file?
No. YouTube receives the audio sent by your encoder; its stream-health tools help you assess delivery, not edit the source file or its transition. Inspect the file’s beginning and ending, and prepare a corrected copy if the quiet section is unintended.
