As one of the best open-source audio recording software, Audacity is used and appreciated by a lot of people. With Audacity, users can record a high-quality audio file and trim it with the in-app tools.

However, Audacity has bugs. If you use it to record sound on your computer, you may find out that Audacity is not recording computer sound or microphone sound at all.

If you’ve encountered such an issue, this tutorial will introduce 4 methods that actually work to solve the ‘Audacity Not Recording Sound‘ issue. You can check out the content below and start to fix your Audacity right away.

Method 1 Make sure you have a recordable audio device

Your Audacity will record the sound from one of the audio input and output devices. But if the two devices are not available to be recorded, Audacity cannot catch the sound from these two devices and can only give you a silent audio file.


The audio input device is the microphone device that can catch the external sound and input to your computer.

And the audio output device is generally a speaker or headphone device that can support computer sound playback.

Here’s how to set the audio devices recordable:

On your Windows computer, right-click the icon of the speaker and go to Sounds. Then, locate the Recording module, there, you can see all the audio devices on your PC that support recording.

If Audacity is not recording computer sound:

Locate an audio output device like a speaker or a headset and right-click on it. Choose Set as Default Device from the list, and click Apply to confirm the adjustment.

When Audacity is not recording mic:

Locate a microphone device and right-click on it, set it as the default device. Hit Apply to use this setting.

In this way, Audacity can catch the sound from the default audio device and you can create an audio file that actually sounds.

Method 2 Set up an audio source on your Audacity

Audacity can record the sound from a certain audio source. If you don’t set up one for it, your Audacity is not recording any sound since it doesn’t know which audio device it should lock to and catch sound from.

On your Audacity, go to Edit and click Preferences. Then, move to Devices, there, you can choose an audio device.


There’re cases that some Audacity users said it was not recording sound but it turned out that they forgot to set up a Playback device to run the captured audio file.

You’d better set up a Playback device to play the captured audio.

After you choose an audio source for Audacity, it can record sound from that source.

It’s very easy to unmute it though, follow the steps below.

On your PC, go to Speaker on the toolbar. Right-click the speaker icon and go to Open Volume Mixer.

On the Volume Mixer window, you can see if your Audacity is muted or not. If it’s muted, click Unmute Audacity.

Method 4 Unmute the tracks on your Audacity

Audacity supports keyboard shortcuts to activate different features. One of the hotkeys is Ctrl + U which is the combination to mute all tracks.

Some people might press it carelessly and fail to realize that they’ve muted all audio sources on their Audacity. For these people, unmute those tracks that you’ve muted before.

On Audacity, go to Tracks on the Menu, and move to Mute/Unmute, there, you can see if you’ve muted tracks.

Audacity Unmute All Tracks

If you’ve muted all tracks on it, press Ctrl + Shift + U to unmute your tracks.
