Screen Studio recording has no sound: microphone and system audio fixes

First, identify which sound is missing

Screen Studio records two separate kinds of sound: your microphone, chosen from the microphone icon, and system audio, the sound your Mac plays, chosen from the system audio button. The fixes differ, so note whether your voice, the app sounds, or both are missing before changing settings. [1][2]

Also confirm the basics: Screen Studio's system requirements are macOS Ventura 13.1 or later and 8 GB of RAM, with an Apple M1 or later recommended. The guide adds that some features depend on your Mac and macOS version. [4]

Step 1: Microphone permission

On first launch Screen Studio asks for accessibility, camera, microphone and screen recording permissions; clicking each permission button opens macOS settings, where you turn on the switch next to Screen Studio. [3]

If you skipped or denied the prompt, Apple's steps are: Apple menu, System Settings, Privacy & Security (you may need to scroll), Microphone, then turn access on for Screen Studio. Apple notes the Recording Indicator in Control Center shows when the microphone is in use or was used recently, which is a quick way to see whether any app is hearing you. [7]

Step 2: Choose the input device and check the level

In Screen Studio, click the microphone icon and choose the device you want. The guide says the white bar under the icon shows whether the microphone is working and collecting sound; if it stays flat while you talk, the app is not receiving audio from that device. [1]

Next check macOS itself: Apple menu, System Settings, Sound, Input, then select the device in the list. Drag the input volume slider up for a quiet source and down if loud speech distorts. Make sure the same device is selected in both places. [9][1]

Step 3: Screen and system audio recording permission

macOS controls system audio capture under its own privacy pane. Apple's steps: Apple menu, System Settings, Privacy & Security, Screen & System Audio Recording, then turn recording on for Screen Studio. Apple says you can allow an app to record screen and audio or audio only; if Screen Studio is not listed, use the Add button below the list and choose the app. [8]

Screen Studio's permissions guide lists screen recording among the permissions requested at first launch and does not list a separate system audio permission, so this pane is where to look. [3]

Step 4: Turn on system audio for the right apps

Even with permission, Screen Studio only records system sound you select. Its guide says to click the system audio button and choose whether to record audio from all apps or from one selected app, and that you can pick a group of apps while the rest are ignored. [2]

A common silent-recording cause is selecting one app and then demonstrating sound in another, for example capturing a browser but playing audio from a desktop app. For a demo, choosing all apps is the safer default; switch to selected apps only when you need to exclude notification sounds.

Step 5: Check volume in the editor

If the sound was captured but you cannot hear it, check the editor before re-recording. Screen Studio's Set Volume guide says to right-click the part of the recording you want to change, choose Set volume and pick a level; this adjusts the whole recording or a specific clip. A level set very low on a clip will sound like missing audio on playback and in the export. [5]

Also check your Mac's output volume and output device before concluding the file is silent.

The 10-second test routine and when to contact support

• Open Screen Studio, choose your microphone and confirm the white level bar moves when you speak. [1]
• Set system audio to all apps. [2]
• Record 10 seconds: speak a sentence, then play a short sound in the app you will demonstrate.
• Stop, play the clip in the editor and listen for both voice and app sound; check Set volume if either is quiet. [5]
• Export the 10-second clip and play it in another player before recording the real take.
• Still silent? In Screen Studio choose Settings, Advanced, scroll down and click Share diagnostics info, then email [email protected] with a detailed description; the guide says diagnostics alone may not be enough. [6]
