No audio output device is installed

Hi, Jacqueline.
Do you still see an exclamation mark on your audio device in device manager? Please make sure latest Windows updates are installed.
My sound is not working there is a red dot with a cross on my toolbar and when I look in my device manager there is an exclamation mark beside Intel High Definition Audio. I have tried uninstalling it and restarting my laptop but it did not work. I purchased AVG driver updater but it did not detect any faults or missing driver. What can I try next?

Thank you for confirming.
When a device has a yellow circle with an exclamation,  this indicates that the device is conflicting with other hardware. Or, it may indicate that the device or its drivers are not installed properly.
Please note that AVG Driver Updater will scan for an out of date driver and downloads the update for it. It is not designed to fix a corrupted driver or missing driver. We'd request to contact Microsoft or your device manufacturer support for assistance or dowload the driver manually from Intel website.

Thank you, tried that but exclamation mark still there and sound not working.
