Most Toshibal laptops now come with a built-in webcam and microphone. These allow you to video chat and conference with other individuals, without installing additional hardware on the system. However, if the internal laptop microphone is not working properly, you have a driver problem (as there is no connection issue and the laptop is automatically set to use the built-in microphone). To correct the problem you need to reinstall the laptop's mic driver.

Difficulty: Moderately Easy

Select "Laptop" and select the model Toshiba you are using, followed by the model number. Click "Go" to view all of the available features on the laptop. Click "Downloads," choose the operating system you are running on the computer. Select "Driver" in the box to the right. Click the driver next to the "Driver Sound"option (if there are multiple "Driver Sound" options choose the most recent driver post as this is the most up-to-date).
