# OBS Not Recording FL Studio Audio? What to Check

Canonical page: https://homeinstruments.com/learn/fl-studio/obs-not-recording-fl-studio-audio/

Before changing drivers, play FL Studio and look at two meters: the Mixer Master and the music source in OBS. That usually tells you where the silence starts. Leave a working mic source alone while you check the music.

## Find the first missing signal

Does FL's Master meter move? No → Check the project . Yes → look at OBS. Does the OBS music meter move? No → Check the capture route . Yes → open the saved file. Is the file silent even with a moving meter? Check recording and playback tracks .

Follow the branch that matches what you can see. Reinstalling FL will not fix a video player listening to the wrong track.

## Start inside FL

Open the Mixer and select Master. Check that you are playing the intended Song or Pattern, that the useful tracks are not muted, and that they reach Master rather than a different hardware output.

A synth can be audible through direct hardware monitoring even when it is not in the DAW mix you are recording. Include the instrument's return in your test. Once FL's intended output is moving, move on to OBS; the capture source cannot repair missing music inside the project.

## FL plays, but OBS hears nothing

Open **Options → Audio settings** and read the selected device. With a manufacturer's ASIO driver, a still Desktop Audio meter often means OBS is watching a different path from the one FL uses.

Use interface loopback if your model supports it. The [manufacturer's OBS instructions][focusrite] are more useful here than a generic device name. Some drivers expose loopback as a normal recording input; others need a different supported source. A microphone-only input will still be silent when the music plays.

With FL Studio ASIO, try the [six-step Windows recipe](/learn/fl-studio/screen-record-fl-studio-with-audio/#quick-setup-fl-studio-obs-on-windows). Test application capture first, then the matching output device if necessary. On Mac, use the [native capture route](/learn/mac/record-daw-audio-on-mac/) and check recording permission.

If switching to OBS stops FL playback, inspect **Auto close** in FL's audio settings. That is a focus/device-sharing issue, not a reason to change video encoders.

## The meter moves, but the file is silent

In OBS, open **Advanced Audio Properties** and find the music source's track assignments. Then check **Settings → Output → Recording** for the tracks actually being saved. A source routed to track 2 is no use if you only record track 1.

Open the recording in an editor or switch audio tracks in your player. If another track contains the beat, your audio survived. The [separate-track walkthrough](/learn/fl-studio/record-fl-studio-mic-and-audio/) gives you a simple listening-mix arrangement.

## If it sounds wrong rather than silent

| What you hear | Try this next |
| --- | --- |
| Hollow, louder or doubled music | Mute duplicate Desktop, application and loopback sources one at a time. |
| Voice twice | Check whether the mic is already inside FL's Master or the interface loopback mix. |
| Mic only on the left | Map that mic input to mono; leave the beat stereo. |
| Crackles only while recording | Test a lighter capture resolution or frame rate with the same project. |
| A fixed camera delay | Record a visible tap and measure the offset. |

After the fix, record a minute that includes a window change and your loudest passage. Check the saved result. Keep OBS if it now does the job; choosing another recorder is a workflow decision, not a required troubleshooting step.
