If your OBS YouTube stream goes silent after you change videos, first check whether the new video is sending audio into OBS. Then check whether OBS is routing that audio to your headphones or speakers, and separately whether it is included in the stream output.
A moving Audio Mixer meter and audible local playback test different parts of the signal path. The steps below cover that distinction and, for a VLC Video source, how to build a shuffled, looping playlist from files you choose. OBS does not automatically watch a folder for new media.
Install VLC with matching architecture
OBS uses VLC’s libraries to provide the VLC Video source. Install VLC in the same architecture as OBS: for example, a 64-bit OBS installation needs a compatible 64-bit VLC installation. If the source is missing from the add-source menu, this is a sensible first check before investigating audio routing.
Check which OBS version you have installed, then install the matching VLC build from VLC’s official download page. Close and reopen OBS after installation so it can detect the VLC components. If you installed a different architecture by mistake, remove or replace it with the compatible build rather than repeatedly adding the source in OBS.
This step is about making the source available; it does not correct a silent file or a monitoring choice. If VLC Video is already in your sources and plays video, move on to the Audio Mixer meter. If you are comparing ways to keep a YouTube channel running without a desktop machine, the options for a 24/7 stream without a PC explain a different operating trade-off from running OBS locally.
Add a VLC Video source
In the scene where you want the videos to appear, use the Sources panel’s add control and choose VLC Video. Give it a name that identifies its role, such as “Main playlist” or “Break clips”. In the source properties, use the playlist controls to add the media files you intend to play.
A VLC Video source is distinct from an ordinary Media Source. The VLC option is useful when you want OBS to play a list of selected files with playlist controls such as shuffle and loop. A single Media Source is simpler for one file, but it is not the same as a playlist. OBS describes the available source types and media behaviour in its Media Sources guide.
Once added, make sure the source is visible and active in the current scene. A source can exist in OBS without currently playing. If you switch scenes or hide the source, the change may affect what is active and what appears in the mixer. In a multi-scene setup, also verify that you are changing the source in the scene actually sent to the live output.
Populate the playlist with chosen files
The playlist must be populated with the files you want it to play. Use the source’s playlist controls to add files from your folders, selecting individual files or the intended set. Check that the list shows the correct paths and that the media is accessible from the computer running OBS. A file moved or renamed after it was added may no longer be available at its saved location.
This is not a folder-watching arrangement. Adding another video to the same folder later does not, by itself, add it to the VLC Video source’s playlist. To include new material, edit the playlist and add the chosen file, then check that it appears in the list. That distinction matters for an always-on channel: a folder can be your organisational source, but the playlist in OBS is the actual set of items queued for playback.
Before going live, test a small representative set of the files you plan to use. Confirm that each plays, that its audio is present if you expect sound, and that the next item loads. A playlist can contain video-only clips alongside clips with sound, so the meter may move for one item and remain still for another. If the channel depends on a planned sequence of scenes and clips, the guide to scheduling a playlist of nature videos for YouTube Live is relevant to deciding how much of that sequence OBS should manage.
Enable Shuffle Playlist
In the VLC Video source properties, enable Shuffle Playlist if you want OBS to select playlist items in a shuffled order rather than follow the listed order. Shuffle changes the order of playback; it does not locate files outside the playlist or add new files from the folder. Review the playlist itself before relying on the setting, because shuffle cannot play items that were never added.
For a devotional channel, for example, you might add the bhajan videos cleared for that channel, then enable shuffle to vary their order. For a local news loop, you may prefer the listed order if a bulletin needs to follow a particular sequence. The right choice depends on the editorial purpose, not on audio troubleshooting. Either way, listen to more than one transition during a test: a shuffled sequence may move from a file with audio to one that has none.
If sound appears to stop only after the video changes, note the name of the new item and watch its meter. If that file has no audio track, a still meter is expected. If it does contain audio, check that playback has started and that the VLC Video source is active. This test narrows the question to the file and source before you alter global audio settings.
Enable Loop Playlist
Enable Loop Playlist in the same source properties when the playlist should begin again after its final item. Shuffle and loop address separate behaviours: shuffle affects order, while loop repeats the playlist rather than stopping after its last item. Check the labels and state shown in your OBS version, as interface details can change; the essential test is whether playback reaches the end and begins again as intended.
For an uninterrupted ambience stream, looping a short, deliberately assembled list may be appropriate. For a programme where the ending should remain visible, repeating may not be what you want. Decide what viewers should see at the playlist boundary, then test the final item and the return to the next item. Audio can appear to fail at that boundary if the next clip is silent, slow to load, or has a different audio mix.
Do not assume that loop means OBS will keep a directory current. It repeats the files already in the playlist. If you have a weekly update, add the new file to the playlist deliberately and verify its playback before the broadcast. For a broader look at building a continuous channel around repeated material, see how to start a 24/7 YouTube playlist stream; the actual source setup and available controls depend on the tool you choose.
Check playback and transitions
Play the source and look at the Audio Mixer. A moving meter beside the source means OBS is receiving audio at that source. If it does not move, check that the playlist is playing, the current file contains an audio track, and the source is active. OBS’s Audio Mixer guide explains the mixer and its monitoring controls.
A still meter does not establish a single cause. Playback may be stopped, a file may be silent, the source may be inactive, or its input may be misconfigured. Test a known audio-bearing file in the same source. If that file produces a meter movement but the problem clip does not, the issue follows the media item rather than the monitoring device.
If the meter moves but you cannot hear the source locally, open Settings → Audio and confirm that the monitoring device is the output device you are actually using. The monitoring device is a separate choice from a source’s monitoring mode. Then open the Audio Mixer gear menu or use Edit → Advanced Audio Properties. Find the affected source’s Audio Monitoring option.
| Audio Monitoring choice | Hear it locally through the monitoring device? | Include it in stream/record output? |
|---|---|---|
| Monitor Off | No | Yes, subject to the source and mix being active |
| Monitor Only | Yes | No |
| Monitor and Output | Yes | Yes |
Choose Monitor and Output if you need both to hear the source yourself and send it to viewers. Monitor Only is for local listening without stream or recording output, so it is the wrong choice for a source that viewers must hear. Monitor Off does not mean the source is muted from the stream; it means OBS is not monitoring it locally. The OBS audio mixer tutorial explains the distinction between monitoring and output.
When the source is inactive, its row may not be available in Advanced Audio Properties, or an “Active Sources Only” filter may hide it. Make the source active and check again. If you use Audio Input/Output Capture sources inside scenes, verify that the expected capture source is present in the current scene. Avoid selecting the same device in Settings → Audio and adding it again as a scene capture source unless you intend that arrangement; duplicated capture can produce echo.
For transitions, keep the mixer visible while moving between two files and, if relevant, between scenes. Note whether the meter stops, resumes after a delay, or continues while local listening drops out. OBS media sources can be configured to close a file while inactive, and may take a short time to reload when shown again. A brief pause at a scene change is not proof that the YouTube output has lost sound.
Verify the YouTube live output
Local monitoring is not the same as what YouTube receives. After confirming the source’s meter and its output mode, check the stream output through YouTube’s live control room or a separate viewer device. Keep the test short and controlled: play a known clip, change to another clip, and listen for the transition on the live feed. Use headphones for the viewer check if nearby speakers could feed sound back into a microphone.
If your local monitoring is audible but the live feed is not, return to Advanced Audio Properties and make sure the source is not set to Monitor Only. Check the active scene and any audio routing or track choices in your OBS setup as well. If the live feed is audible but your headphones are not, the problem is likely on the local monitoring path: confirm the configured monitoring device and per-source setting rather than changing YouTube stream settings first.
If the failure follows one video, inspect that file and its audio track. If it follows a scene, check which sources are present and active in that scene. If it follows the output device, test the device selected in OBS and the system’s current listening output. This comparison is more useful than treating every silent transition as the same OBS bug; the cause depends on your operating system, OBS version, and source configuration.
For the broadcast itself, verify that YouTube is receiving the intended live picture and sound before leaving the channel unattended. A working local meter cannot confirm what the public feed sounds like, and a successful test of one clip does not confirm every file in a shuffled playlist. If you are diagnosing other aspects of a long-running broadcast, the bitrate and upload-speed checklist covers a separate part of the live path; it should not be used as a substitute for checking audio routing.
If repeated maintenance of a local OBS setup is the larger problem, StreamNeo can remove the need to leave your own computer on for a file-based YouTube broadcast: you upload the video, provide your YouTube stream key, and the broadcast runs with monitoring and automatic restart if it drops. It is YouTube-only, and it does not determine whether your media has rights or whether YouTube will approve a stream.

FAQ
Why does the OBS meter move when I cannot hear anything?
The meter shows that audio is reaching the OBS source, not that OBS is sending it to your chosen listening device. Check Settings → Audio for the monitoring device, then check that source’s Audio Monitoring mode in Advanced Audio Properties.
Which setting lets me hear the source and send it to YouTube?
Choose Monitor and Output for that source. Monitor Only is local monitoring without stream or recording output, so viewers will not hear a source configured that way.
Why does audio stop after I change videos?
The new file may have no audio, may not have started playing, or may be inactive while OBS reloads it. Watch the source meter during the change and test the new clip separately; the symptom does not identify one universal cause.
Will VLC Video pick up a file I add to its folder later?
No. Add chosen files to the source’s playlist using its controls. Shuffle and Loop affect the playlist contents, but do not make OBS watch a folder for new media.
