Fix: Audacity recording device error or while opening sound device issue

When it comes to mixing or cutting your favorite tracks or recording something, Audacity always comes at the top of your list of choices. This free audio editor usually works quite well, but sometimes while trying to record something or editing an existing track, Audacity may not work or show an error message “Error opening sound device. Try changing the audio host, recording device, and the project sampling rate” on the screen. You won’t be able to record (and, or play) anything further unless you solve this issue manually.

Workarounds

1. Just close Audacity and relaunch it. Usually, it should solve the issue.

2. If this is the first time the problem has occurred, restart the system and then test Audacity.

3. Make sure that the audio device or the microphone is plugged in properly to the system. Unplug it from the machine and replug it.
