If OBS audio seems to disappear during a 24/7 YouTube radio stream, first check the source’s mixer meter while the problem is happening. A quiet meter points you towards playback, device selection or the input path; a moving meter with dropped frames or disconnections points you towards the stream connection instead.
Those are different failures, even when listeners describe both as “the music stopped”. The meter is not a complete guarantee that the audience is hearing clean audio, but it gives you a useful place to start before changing settings at random.
Identify what listeners mean by dropped audio
“OBS audio source keeps disconnecting”, “OBS music stops playing” and “the stream has no sound” can describe different points in the chain. A file might have finished playing, a capture device might have become unavailable, OBS might be receiving audio normally while its connection falters, or the audience might hear silence even though your local monitor sounds fine.
Think of the path in stages: the file or device produces sound; OBS receives it; OBS mixes and encodes the programme; the connection carries the stream to YouTube; viewers receive and play it. A fault at one stage does not prove a fault at another. In particular, dropped video frames are not evidence by themselves that an audio source stopped.
When somebody reports a problem, note roughly when it occurred and what they heard: continuous silence, a gap, crackling, or a stream that stopped and resumed. Then check the OBS mixer and the stream status around that time. Avoid restarting everything before you have looked, if it is practical to do so; a restart can remove the symptoms you need to distinguish.
If the stream uses a playlist of local files, check the playback path as well as the live connection. The practical setup questions in how to stream a playlist on YouTube Live 24/7 are relevant here: a continuous broadcast still depends on the content source continuing to play.
Watch the source meter during the problem
In OBS, look at the meter for the particular source that should be producing the radio audio. If you use multiple scenes or sources, make sure you are looking at the source in the active scene rather than an unrelated desktop or microphone meter. A meter that moves when the music is playing tells you that OBS is receiving some signal from that source at that moment.
If its input indicator is absent or the meter is not moving, treat that as evidence that audio is not reaching OBS at that point in the chain. It does not identify the cause on its own. The file may be idle or finished, the selected device may be wrong, or an interface may be disconnected. OBS’s technical audio guide describes a missing input indicator as no audio being streamed to OBS and includes a disconnected audio interface as one possible explanation.
If the meter is moving while listeners report silence, do not immediately replace the source or reselect the device. The signal may be disappearing later in the chain, or the meter may show activity that does not represent the audio you expect. Check whether the source is the intended one, whether OBS monitoring sounds normal, and whether OBS reports dropped frames or disconnections.
The difference matters because the remedies do not overlap neatly. Enabling Loop can help a file that has reached its end; it will not stabilise a weak network connection. An Ethernet connection may help with transport stability; it will not make an unselected audio device deliver sound. Use the observation to choose the next check, rather than applying both classes of fixes at once.
If the meter is still, trace the input path
Start upstream of OBS. For a local file, confirm that the file is actually playing and that its audio is audible outside the OBS meter, if you can check without disrupting the broadcast. For an application capture source, confirm that the application is open and producing audio. For a hardware input, check that the device is connected, powered if required, and selected as the source you intend to use.
If you recently changed an operating-system audio setting, moved a USB device, updated a driver, or edited a scene, repeat the device-selection check. OBS’s Quick Start Guide notes that desktop audio and microphone capture may be configured by default, but recommends selecting devices manually in Settings → Audio when needed. Default devices can change, and a setting that worked before a system change is not proof that the same input is selected now.
For a Media Source playing one audio file, open its properties and check the file path and playback options. The Loop setting controls whether playback starts again when the file finishes. “Restart playback when source becomes active” is a separate behaviour: it controls what happens when the source becomes active, not whether a completed file repeats indefinitely. “Close file when inactive” unloads a hidden source, which can introduce a delay when it is shown again.
For a playlist, OBS’s VLC Video source can play a playlist and has a Loop Playlist option. This source depends on VLC being installed; the OBS documentation specifies that 64-bit OBS requires 64-bit VLC. Do not assume that a playlist has stopped because the connection dropped, or that it will continue because OBS remains open. Confirm that the player and playlist are behaving as expected.
Keep a note of what you changed and whether the meter resumed. If you alter several settings together, you may restore audio without learning what failed, making the next overnight interruption harder to diagnose. A small, reversible check is more useful than a broad reset when the stream is already running.
Check interfaces and source availability
An audio interface, USB microphone, mixer or other capture device can disappear from OBS’s point of view even if the scene still looks unchanged. Verify that the intended input is present in the operating system and selected in OBS. If you use a scene-specific Audio Input Capture source, inspect that source’s device setting in the scene where the radio is running.
There are two common ways to capture a device: set it globally under Settings → Audio, or add it as an Audio Input/Output Capture source in a scene. OBS warns that capturing the same device both globally and as a scene source can cause echo. If you need a device only in selected scenes, a scene source can be useful; disable the duplicate global capture for that device rather than letting both paths run unintentionally.
Source availability differs by operating system. OBS lists Audio Input/Output Capture for Windows and macOS; on Linux, its guide points users to ALSA or PulseAudio sources. Use the source type intended for your system instead of copying a Windows setup step onto a Linux machine.
If an interface disconnects intermittently, check the physical connection and whether the device remains available to the operating system when the sound disappears. A loose cable or device power issue is plausible only if the observation supports it; it is not a conclusion from a still meter alone. If reconnecting a device restores the meter, record that outcome and check whether it happens again before leaving the system unattended.
This is also a useful point to review scene changes. A source can be present in one scene but absent or configured differently in another. If a scheduled or manual transition changes scenes, test the transition and verify the active source’s meter on both sides. The same principle applies to a video loop that carries audio: the picture continuing does not establish that its audio is reaching the mixer. For other OBS scene troubleshooting, see how to fix a black screen on a pre-recorded YouTube live stream; a visual symptom and an audio symptom need their own checks, even when they share a scene.
If the meter moves, inspect stream connectivity
A moving source meter shifts the next check downstream. Confirm that the correct source is active and that the signal sounds right through OBS Audio Monitoring, then inspect OBS’s stream status for dropped frames or intermittent disconnections. If the audio is audible in monitoring but the audience reports silence at the same time as connection trouble, investigate transport rather than starting with the input device.
OBS’s Stream Connection Troubleshooting guide associates dropped frames and intermittent disconnections with an unstable connection to the ingest server or a bitrate the connection cannot sustain. It recommends a wired connection when Wi-Fi is unstable. That can be a sensible transport check, but it cannot repair a stopped local file, an unplugged audio interface or an incorrectly selected source.
Also check whether the report is limited to one viewer or occurs consistently for several listeners. Viewer playback conditions can differ, so a single report does not establish that OBS stopped sending audio. Compare the timing with OBS’s own status and, if possible, a recording or another independent playback check. The aim is not to dismiss the report, but to locate where the evidence changes.
If OBS shows no connection issue and its meter continues to move, use a normal recording to review what OBS actually produced. A recording with sound while the live audience reported silence suggests a different investigation from a recording that is silent too. Keep the comparison bounded: a recording can confirm the local output at that time, but it cannot establish what every viewer received.
Relate dropped frames to connection or bitrate
Dropped frames refer to the stream’s connection and delivery, not to an audio input meter. Treat them as a reason to examine connection stability and the configured bitrate, rather than as proof that OBS’s source stopped supplying audio. Conversely, a still audio meter does not establish a network fault just because the broadcast is live.
OBS recommends setting video bitrate in relation to stable upload capacity. Its guide gives 75% of total upload speed as a starting point, not a guarantee or a universally suitable value. If you use that guidance, assess the connection’s stable capacity rather than relying on a best-case speed test, and make one change at a time. A radio stream may use modest video, but the bitrate still needs to fit the actual connection and the rest of the network’s use.
The same guide suggests investigating the ingest server choice, VPN or security software, network-optimisation software, drivers, router, modem, cables and other network hardware. These checks are relevant when the evidence points towards transport. OBS also recommends wired networking when Wi-Fi is unstable; an Ethernet cable may reduce one source of variability, but it does not guarantee a stable stream and will not fix an audio capture fault.
| What you observe | Where to investigate next | What the observation does not prove |
|---|---|---|
| Source meter is not moving | File or application playback, selected device, interface connection and source settings | That the network is at fault, or which input-path component failed |
| Source meter moves, with dropped frames or disconnections | Connection stability, bitrate, ingest path and network equipment | That the audio source itself stopped |
| Source meter moves, with no corresponding OBS connection warning | Confirm the source and monitoring; compare with a recording and viewer reports | That every viewer receives clean audio |
For a continuous radio channel, a useful baseline is a stable wired connection, a bitrate that the connection can sustain, and a source configuration you have tested. It is not a substitute for checking the evidence during an interruption. If you are comparing a computer-based setup with a cloud-based way to keep a prepared video running, the question of whether an Indian VPS can run a 24/7 YouTube stream is a separate operating decision; it does not change the meter-versus-connection diagnosis in OBS.
Run a long-duration test and record symptoms
Before leaving a stream unattended, test the full chain in the way you intend to use it. Check the source meter, listen through Audio Monitoring, confirm the selected device and playback behaviour, then make a recording using the normal settings and listen back. OBS’s mixer guide recommends monitoring the meters, listening as early as possible and again as the signal reaches OBS; its Quick Start Guide encourages a short test before going live rather than jumping straight into a broadcast.
A short test can catch an obvious routing mistake, but it cannot demonstrate that a source or connection will remain healthy indefinitely. No test duration guarantees that a 24/7 stream will not fail. Extend the test long enough to exercise relevant events in your setup: a file reaching its end, a playlist moving to the next item, a scene transition, or the computer’s usual network conditions. The right test is the one that covers the things your actual channel does.
Keep a simple incident log. Record the time, active scene and source, whether the mixer meter was moving, whether OBS showed dropped frames or disconnections, what a local recording contained, and what changed when audio returned. If you operate from India and rely on a local network that is shared with other people or devices, note those conditions too; a time correlation may help, but it is not itself proof of cause.
Use the log to make one targeted adjustment, then repeat the relevant part of the test. If the meter stopped, verify the file or device path. If the meter continued while connection indicators changed, test the connection or bitrate. If OBS’s meter and recording are normal but viewers still report silence, gather the timing and playback details before altering your source configuration.
For operators who want to avoid leaving a personal computer running the prepared broadcast, StreamNeo can take the uploaded video and YouTube stream key and keep that file-based broadcast running while the computer is off, removing the need to maintain the local OBS playback path for that use case. It is YouTube-only; it does not remove the need to prepare the media or check the channel and stream before relying on it.

FAQ
Does a silent OBS meter prove the audio interface disconnected?
No. It indicates that audio is not reaching OBS at that point, but the cause could be an idle or finished file, an incorrect device selection, a disconnected interface or another upstream issue. Check playback and device availability before settling on a cause.
Can dropped frames make an audio source disappear?
Dropped frames point towards connection stability or a bitrate the connection cannot sustain; they do not show that a source stopped delivering audio to OBS. Check the source meter during the incident, then use connection indicators to decide whether to investigate transport.
Should I enable Loop on every OBS audio source?
No. Loop is useful when a local Media Source file should repeat after it finishes. A device capture source does not need that setting, and playlist sources have their own playback behaviour; check the source type and intended programme first.
How long should I test a 24/7 stream before leaving it alone?
There is no validated test duration that guarantees an uninterrupted broadcast. Test the normal playback, transitions and connection conditions you depend on, and review a recording before going live; continue to monitor and log symptoms rather than treating one successful test as proof it cannot fail.
