Error 801 MIT App Inventor

[Just_a_CoLyA]

While creating sound recorder, I encountered error 801 which does not allow recording any sound:
"ERROR 801: An unexpected error occured while recording sound".
I rebuilt the application and looked for a YouTube video about this error but nothing is said about it anywhere.
