Firstly, in order to fix the issue, navigate to Start, type dxdiag in the Search programs and files field and open the utility. Click the Audio tab, check your sound card model and download and install the latest drivers available from the developer's web page. After that, upgrade Cubase LE to the latest version using the package from the official website. Before downloading the package, you will need to create an account on Steinberg website. If you still have problems, you can check Software Informer database for another similar sound recorder.
