When OBS audio goes silent during a YouTube radio stream, trace the signal from the source to YouTube rather than changing settings at random. The first useful check is whether the relevant OBS mixer meter still moves at the moment you hear silence.
A flat meter points you towards playback, a device, system levels or source processing before OBS. A moving meter means audio is reaching the mixer, so check mute and output routing, then compare an OBS recording with the live YouTube stream. The right cause depends on how your audio enters OBS, your operating system and your OBS version.
Start with the silence, not a settings reset
If the stream has been running normally and then becomes quiet, resist the urge to restart everything at once. A restart may restore sound without showing whether the source stopped, OBS stopped capturing, or the signal was lost later in the path. That distinction matters if you need the channel to last through another night.
At the moment of failure, note what you can observe: whether the originating player or device is still active, whether the expected source is in the active OBS scene, and whether its mixer meter moves. If possible, make a short local recording while the silence is happening. These checks take little time and preserve evidence that a restart would erase.
For a radio playlist, the source might be an OBS media source, a browser, desktop audio, or a physical input. Do not assume that the player showing a play icon is producing sound: check the output itself, and listen at the device or application if you can. If it is an external device, check that it remains connected and powered, and that its own controls have not changed.
If silence starts only after the stream has run for a while, use that timing as a clue, not a diagnosis. A source may have stopped, a device may have disconnected, or the signal may still be arriving in OBS but not reaching the stream. The timing alone does not prove a particular fault. Leave the channel in its failed state long enough to inspect the meter and, if practical, record a sample.
Confirm the source is still playing
Begin at the point where the sound originates. If the radio is playing from an application, check that playback continues and that the application is sending sound to the expected output. If it comes from an audio device, inspect the connection and controls. If a browser or media source supplies it directly to OBS, check that the relevant source is present and active in the scene currently being broadcast.
This check separates a stopped source from a capture problem. A playlist can appear loaded while playback is paused or its current item has ended; a device can remain visible on screen after losing its connection. These are possibilities to test, not assumptions about your setup. Check what the source is actually doing when viewers report silence.
The same principle applies to a continuous music playlist: the file or station must be producing sound, and OBS must be using the intended source. If you are still setting up the channel, the guide to streaming a continuous Indian classical flute playlist can help with the broader playlist workflow; it is not a substitute for checking the live signal when audio drops.
OBS’s Audio Mixer Guide recommends starting with the device and then checking the operating system’s mixer and individual application volume. Follow that order where it applies: verify the device or application first, then inspect levels, and only then move downstream to OBS’s mixer. If the source itself has stopped, adjusting stream output cannot restore its sound.
Read the OBS mixer meter during the fault
Watch the meter for the source that should carry the radio audio while the sound is absent. A moving meter means OBS is receiving some audio at that point in the path. A flat meter means the expected audio is not reaching that mixer input, so investigate playback, the selected capture device, system or application volume, connection, and source processing before YouTube delivery.
Take care to watch the right row. A scene can contain several audio sources, and a meter moving for a microphone or another application does not prove that the radio source is reaching OBS. Identify the source that should carry the programme, then observe it while the problem is occurring. OBS’s Audio Mixer Technical Details explains where its input indicator sits in relation to filters; temporarily disabling source filters can help establish whether processing is suppressing the signal.
If the meter is flat, avoid turning up every fader. First verify that playback continues, that the correct device or source is selected, and that its operating-system and application levels are not muted or reduced. Then test the filters as described below. Raising unrelated levels can create clipping when the missing signal returns, without fixing the cause of silence.
If the meter moves, capture is occurring, but that alone does not prove audio is in the encoded programme. Check whether the source or mixer channel is muted, whether its fader is lowered, and whether it is routed to the stream output and the audio track OBS is sending. OBS labels and mixer layouts can change between releases, so look for the function rather than relying on a menu path from a different version.
Monitoring is another separate question. Hearing a source through an OBS monitoring device tells you something about monitoring, not necessarily whether the source is being sent to the stream. Conversely, not hearing monitoring does not by itself prove that stream output is silent. Check the output routing and selected stream track as well as what you hear locally.
Check operating-system and application levels
If the source appears to be playing but its OBS meter is flat, inspect the operating system’s sound controls. Confirm that the relevant output or input device is selected and that the application is not muted or assigned to a different device. The names and layout of these controls vary by operating system and release, so use the controls available on your system rather than following steps written for an unspecified platform.
For desktop audio capture, the application may be sending sound to a different output from the one OBS captures. For a physical input, the selected device in the operating system may differ from the device selected in OBS. Check both ends of that connection. If the device is no longer present, reconnect it or select the appropriate available input, then confirm that the mixer meter responds before changing stream settings.
A useful test is to play a known sound through the same application or device and watch the correct OBS meter. If that test moves the meter, the signal path can work under those conditions; return to the radio source and compare. If it does not, stay focused on device selection, application routing and system levels. Do not treat a successful test from a different audio path as proof that the radio source is configured correctly.
If your setup depends on a computer staying awake, or a device that can sleep or disconnect, those may be hypotheses worth checking when the timing supports them. The article’s symptom alone does not establish that either occurred. Look for evidence at the failure point: did playback stop, did the device disappear, or did the OBS meter remain active?
Inspect OBS source settings and filters
Once you know whether the meter is flat or moving, inspect the relevant OBS source rather than changing every source in the scene. Confirm that the source is enabled in the active scene and that its input or capture choice matches the way audio is meant to enter OBS. If the source uses a physical device, check that OBS has not been left with a different or unavailable device selected.
Filters can affect what reaches the mixer. Temporarily disable them one at a time while watching the meter and listening to a local recording, then restore or adjust only the filter that evidence implicates. A filter might reduce or suppress audio depending on its settings; do not infer that it is responsible merely because one is present. The technical details guide notes that the input indicator is upstream of filters, which is why testing with filters disabled can help distinguish incoming audio from processed output.
Next inspect the mixer state. Check mute, fader position and routing for the radio source. If audio is mixed across sources, verify which channels are included in the stream output and which track is selected for streaming in your installed OBS version. Interface text may include a warning where no tracks are selected, but the exact labels and location can vary. The principle is to confirm that the source’s audio is assigned to the output YouTube receives.
If you changed a source setting, filter or routing choice, make one change at a time and record a short test. That keeps the result interpretable. Aim for a clean signal that does not clip rather than raising levels indiscriminately; the final output should remain below 0 dBFS. After recording, listen back to the file before relying on the live stream.
Separate local audio failure from stream output
A local recording made during the silence is a valuable dividing line. If it is silent too, the problem is likely at or before the OBS output captured in that file: source playback, capture, processing, mute, fader or routing. Recheck the meter and OBS output state. If the local recording contains the radio audio but YouTube playback does not, move on to the live output and delivery path.
Compare like with like: use a recording made during the actual fault, and check the same section of the live stream. A recording from before the failure cannot establish what happened later. If viewers report different results, note whether silence affects one viewer or several people on different connections. That observation can help distinguish a single playback or viewer issue from a problem affecting the stream more broadly, though it is not conclusive on its own.
YouTube’s live-stream troubleshooting guidance recommends inspecting the encoder output and local archive, then checking for reported errors in Live Control Room. If the encoder and local archive look and sound healthy while viewers hear silence, examine dashboard warnings and consider whether the outbound connection or platform-side delivery is involved. Do not assume that a healthy local file guarantees every viewer receives sound.
The OBS guide to configuring a 24/7 YouTube music stream on JioFiber may be useful for broader streaming setup questions, but a silent stream still needs this comparison. If OBS’s recording is audible and the live stream is not, gather the time of the incident, recording evidence and any dashboard errors before changing encoder settings. That gives you a clearer basis for the next test.
Test YouTube playback and watch for recurrence
After a change, make a local recording using the same source and OBS scene you plan to run. Listen to it, check that the sound is present and clean, and inspect the meter. Then verify the actual YouTube stream, not only OBS’s preview or monitoring output. A brief test can confirm that sound reaches YouTube at that moment, but it does not establish that a later silence has been fixed; continue watching the source and meter through the period when the fault previously appeared.
If the recording is healthy but YouTube reports encoder errors or viewers still hear silence, use the Live Control Room’s current diagnostics. Keep track of when the problem began and whether the source and OBS meter continued. That record helps separate a source stoppage from a downstream issue and prevents repeated changes that obscure what happened.
Only investigate audio channel format if the evidence points towards conversion or an incompatible layout. YouTube documents support for mono, stereo and 5.1 input; other channel configurations may convert unreliably to stereo. Its 5.1 surround-sound guidance gives format-specific requirements for 5.1, including a 48 kHz sample rate and 384 Kbps audio bitrate. Those details apply to 5.1 delivery, not as a general fix for a stereo radio stream that has suddenly gone silent.
A practical recurrence note can be brief: record whether the source was playing, whether its OBS meter moved, whether the local file contained audio, and whether the YouTube problem affected more than one viewer. This creates a useful comparison if silence returns. For an always-on channel, remote checks also matter; the guide to monitoring an always-on YouTube stream remotely covers that wider task, while the meter and recording remain your first evidence about where this audio path failed.
If you are considering how to keep a file-based radio programme running without leaving your computer on, StreamNeo removes that specific operating burden by turning an uploaded file into a YouTube live stream that continues with your computer off. It is YouTube-only; it does not replace checking your source file or verifying the sound on the live channel.

FAQ
Why does OBS audio go silent after streaming for a while?
The timing does not identify one cause. Check whether the source is still playing and whether its OBS meter moves at the moment sound disappears; then compare a local recording with YouTube playback to locate where the signal stops.
Why does the OBS meter move, but YouTube has no sound?
A moving meter shows that audio reaches the mixer, not necessarily that it is included in the stream output. Check mute, fader, output routing and the selected stream track, then listen to a local recording and inspect Live Control Room diagnostics if the recording is audible.
How can I tell if OBS or YouTube is causing the silence?
Make a recording during the fault and compare it with the live stream. If both are silent, investigate the source and OBS path; if the recording is audible but YouTube is not, look at stream output, encoder errors and delivery diagnostics.
Should I change OBS’s audio channel format?
Not as the first response to sudden silence. Check the meter and local recording first; consider channel format only if evidence points to a conversion or layout issue, and use YouTube’s current guidance for the format you actually send.
