Audacity error message

I just downloaded the Audacity 2.x on my windows 7 pc and all I get is this message and I have no clue what to do. Can you please help me?

Audacity error message:

Error while opening sound device. Please check the input device
settings and the project sample rate.

See this Frequently Asked Question: .


I went there but there was no help because I had tryed that before I asked this question. I did discover however that there is no ‘input device found’. So how do I solve that problem?

What sort of input device are you trying to record from? A microphone plugged into your computer sound card?
Check in the Windows Sound Control Panel to see if the device that you wish to record from is enabled.

I keep at it and finely got things working, it seems that somewhere in the computer system that the sterio thing was muted. Thank you for your help
