Measure at the start and at later points, then compare those observations with stream-health messages and encoder diagnostics. A constant delay and cumulative drift are different problems; neither has a universal OBS setting or FFmpeg flag that fixes every stream.
Identify the kind of sync problem
At a known start point and at later intervals, note whether audio leads or lags video and estimate the gap. Use the same identifiable event each time—for example, a visible action paired with a sound—so the comparison is meaningful. With a mostly static radio image, use synchronized visual cues if available, or examine the encoded output and playback statistics.
- Fixed offset: the gap is about the same at the beginning and later. Investigate a start-time or processing delay.
- Growing drift: the gap changes over time. Investigate ongoing timing, clocks, timestamps and resampling; a one-time offset cannot establish a rate correction.
- Intermittent mismatch: sync changes around interruptions or at particular times. Correlate those moments with encoder logs and YouTube’s timestamped health messages.
- Playback-specific mismatch: the local output appears synchronized but YouTube playback does not. Check the delivered stream and another playback device or player before changing the source.
Record the direction and approximate size of the gap at each observation. For a 24/7 stream, a brief check can miss a slow change.
Compare the local output with YouTube playback
If the local output is already drifting
Focus first on the source and encoder chain: how audio and video are timed, whether they depend on separate device clocks, and whether timestamps remain continuous. The actual cause depends on the specific production chain; a measurement alone does not identify which component is responsible.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
If the mismatch appears only on YouTube
Inspect the stream sent to YouTube, Live Control Room’s health messages, and a second playback device or player. Buffering and playback can make a live presentation appear different from the encoded source, so verify the symptom before altering source timing.

FFplay synchronization statistics
FFplay’s documented -stats output includes stream position, duration, codec parameters and audio/video synchronization drift. Use it to observe whether the measured gap changes; it reports the condition, not an automatic correction. The FFplay documentation describes these playback statistics.

YouTube Live Control Room health messages
YouTube says, “The Live Dashboard and Live Control Room check for errors in the stream that you’re sending to YouTube.” Its errors are timestamped and classified by severity. Note whether a message coincides with the point at which sync changes, and address reported ingestion errors before interpreting a retest. See YouTube’s live streaming error messages.
OBS dropped frames and connection state
Check OBS’s dropped-frame counter, connection indicator and logs. OBS explains that when the counter is increasing and the connection square is yellow or red, the connection to the server is unstable or cannot keep up with the configured bitrate; OBS drops video frames to avoid buffering. That is useful evidence about the connection path, but it does not prove that network trouble causes every case of progressive audio drift. The OBS dropped-frames guidance explains this indicator.

Check the YouTube stream configuration
Confirm the stream against the current recommendations in Live Control Room for its format and resolution. YouTube’s live-stream error guidance specifies H.264 video; AAC or MP3 audio; one audio stream; mono or stereo audio; and a 44.1 kHz audio sample rate. It recommends a 128 Kbps audio stream bitrate, keyframes every two seconds, and no less frequent than every four seconds. These are delivery settings, not a diagnosis or guaranteed cure for drift. YouTube lists them in its live streaming error guidance.
Choose a correction from the evidence
For a measured fixed offset
A constant delay may justify a measured delay adjustment in the component where that delay is introduced. Confirm which side leads, where the offset first appears, and whether it stays constant before applying the adjustment. Do not use an arbitrary delay value as a fix for a gap that grows over time.

For a growing gap
Investigate continuing timing and clock behavior, timestamp continuity, resampling, and the relationship among audio and video sources. FFmpeg documents audio filters such as aresample, but filter behavior and side effects depend on the installed version and configuration. Consult the FFmpeg filter documentation and validate a proposed change before using it on a live output. There is no source-established generic command or flag that corrects every cumulative drift problem.
Make one change at a time
Preserve the current configuration, change one relevant setting, and compare measurements again. Multiple simultaneous changes make it harder to tell which one affected sync.

Retest for a representative duration
Test on the actual YouTube stream long enough to see whether the original trend returns. Keep a simple record of the start and end offsets, encoder logs, dropped-frame counts, timestamped stream-health messages and the one change made. A short successful check does not establish stability across a 24/7 operating cycle.
Common troubleshooting branches
| What you observe | What to check next |
|---|---|
| The gap is similar at the start and later | Locate the stage that introduces a constant delay; measure before applying a delay adjustment. |
| The gap grows during the broadcast | Check source clocks, timestamps, resampling and the relationship between audio and video sources. |
| Local output is synchronized, YouTube playback is not | Review Live Control Room messages and compare another playback device or player before changing source timing. |
| OBS dropped frames increase and its connection indicator is yellow or red | Investigate whether the connection can sustain the configured bitrate, using OBS counters and logs. |
| A YouTube health error appears near the sync change | Address the reported ingestion issue, then repeat the measurement. |
