Recording has no sound may crop up due to improper recording settings, system settings, out-dated audio driver or conflict between multiple audio drivers.
As a general rule, microphone sound is naturally easy for screen recorder to capture directly, while system audio, because of potential copyright reason, makes recording a challenge. Hence, RecMaster screen recording products take advantage of its own virtual audio driver to route the system sound to speaker for capture. The Windows version has bundled this driver into its setup file. However, RecMaster for Mac still needs users to install the audio driver named “Aunboxsoft Audio Device” manually.

After you have got familiar with this workflow, let’s check several possible solutions to muted/silence recording.
If the system sound is muted or you didn’t plug the mic into microphone jack rightly, no sound will be captured. Set Windows for example, you can navigate to the Sound settings to enable the speaker or headphone playback and fine tune the speaker volume to a relatively higher value (at least 50%) from Volume Mixer/Control.
If you get a failure when recording system sound on Mac, you can close RecMaster app and then check whether the “Aunboxsoft Audio Device” is selected under Settings -> Sound -> Output. Also, navigate to Input section to ensure the option is picked as its Microphone. After that, do quit and open RecMaster again to start the recording. Also, you can restart the computer to begin a new recording with RecMaster.
If you get such soundless video when recording Zoom meetings, please go to Audio Settings and pick “Aunboxsoft Audio Device” as the default speaker.
Note that currently RecMaster doesn’t support recording audio from any bluetooth audio device.
If the device driver is out of date, audio capture may encounter errors. You are suggested to visit the official online support center of your computer to obtain the latest audio driver and get it installed on your machine.
Either pre-installed by default or installed manually by you on the computer, any third-party audio related components or software may contribute to conflict so that RecMaster can not grab the audio signal normally. So, go over the one(s) on your computer, disable or uninstall it/them depending on the circumstances.
