Common troubleshooting steps
If Audacity shows you an error message when trying to record or playback audio start using Transport > Rescan Audio Devices to update the list of devices.
Error message when trying to playback audio
Refresh the list of devices
After rescanning audio devices try selecting a different host using the Audio Setup button and make sure the desired device is selected as your Recording or Playback Device
Try changing the Host
Recheck that the correct device is selected
If the error is still present try changing the Project Rate to a different value:
Set Project Rate to a different value
Verify that the Recording Meter Toolbar and the Playback Meter Toolbar sliders are set to an appropiate level. Place the mouse cursor over the meter and Audacity will display the corresponding level
Some operating systems may block access to the microphone for untrusted apps. You need to allow microphone access for Audacity in order to record.
- 1.Open Settings
- 2.Go to Privacy or Privacy & Security
- 3.Go to Microphone
- 4.Toggle on Microphone Access, Allow apps to access your microphone, and, if available, Let desktop apps access your microphone
- 1.On your Mac, choose Apple menu > System Preferences then click Security & Privacy in the left-hand menu and the click the Privacy tab.
- 2.Click Microphone in the left-hand menu.
- 3.Select the checkbox next to an application (Audacity) to allow it to access the microphone.
If you have installed Audacity as a Snap or Flatpak, you may need to go to the System settings > Application settings
Your operating system may disable the microphone in general. You need to enable it in order to record.
- 1.Open the Sound control panel and select the Recording tab
- 2.Make sure that Show Disabled Devices is selected
- 3.Look for your microphone and Enable it
Enabling Microphone using Windows Sound control panel
After enabling your microphone use the Audacity Transport - Rescan Audio Devices option to update the list of available devices.
It is recommended to update drivers for audio devices you are using. The way to do that depends on the specific device but in general it is recommended to visit the manufacturer support website.
Some audio devices install a complementary application that provides options to check for firmware and driver updates.
Windows users can try to manually update drivers using Device Manager, before looking for drivers on the Internet. This is easiest, but may not necessarily find the latest or most appropriate drivers.
- Windows 10 / Windows 11: Right click the Start button and select Device Manager
- Windows 8 / Windows 7 / Windows Vista: Click Start > Control Panel then using the "Category" view, click "Hardware and Sound", find "Devices and Printers" near the top of the screen then click on "Device Manager" (the last item in the list underneath). "Icons" views have a direct link to Device Manager, as does "Classic View" on Windows Vista only.
Then expand Sound, video and game controllers by clicking on the + sign, right-click over the sound device and click Update driver.
Using Device Manager to manually update drivers for an audio device
After the update (even if more recent drivers were not found), you should right-click over the device again, click Properties and then on the Driver tab to check the "Driver Provider". You don't want drivers from Microsoft - in most cases these are only generic drivers, not specifically matched to your hardware. This often leads to problems such as not being able to select the correct input, or recordings not being made correctly. These must be replaced with drivers made by the manufacturer of your hardware, so they are correctly matched to that hardware.
If you have now got updated non-Microsoft drivers, try them and see if your recording problem is solved.
Use the Recording Meter Toolbar to check the audio level that Audacity is receiving from the selected Recording Device. Click on the toolbar to Start/Stop monitoring the audio level.

If there is no level present on the meter you could check if your device provides some physical control to mute or set the audio level.
USB Sound Card with Microphone Mute and Level controls
USB Interface with Microphone and Instrument gain controls
If the controls on your device are properly set you should check the connections between the computer and the recording device.
Due to a Windows limitation, you cannot use WASAPI on a USB device while listening back on an onboard audio card. Use MME or DirectSound instead, or use the USB device for both the input and output (if possible).
