Under the devices section, navigate to the channels option and set it to channel 1 or channel 2.

To fix this, head over to menu bar for Audacity, click edit and select preferences. Errors can therefore occur if Audacity is trying to record more than one channels.

Another reason for this error is the fact that some soundcards use a channel or two for audio.

Most sound cards support the 44100Hz and 48000Hz rates, if you have a different sample rate being used, change it to either of the following and test for recording.

This sample rate is positioned at the bottom left corner of the program window as “Project rate”.

If you still get the error, ensure that the default format set for the recording and playback devices uses the same number of recording channels and sample rates as Audacity. Re-open the Audacity app and see if it runs fine.Click OK and close all the open windows.On the properties dialogue, navigate to “device usage” and select “enable/use this device”. If you do find a new device displayed, right click on the new-found device and navigate to “properties”.

At this point, the next thing to do is to reinstall your sound card driver.
