I can see different recording devices in my computer as shown in following printscreen There are two options for Microphone and one is Line in. i m using Acer Aspire 4710. when i open sound recorder and start recording it either tells me that there is no recording device on this computer or if it records the audio, playing it gives no output sound. how can i solve this problem. Any suggestions are highly appreciated
As far as the sound playback issue goes, you might want to try the Windows Sound Diagnostic page: http://windows.microsoft.com/en-us/windows/help/no-sound-in-windows
With the microphones, you might want to see if you're plugging them into the right ports or try them on different computers to see if it's a hardware issue.
Right click in an empty space in the Recording tab and tick Show Disabled, and Disconnected devices, "Stereo Mix" is what you need but is disabled at the Sound driver level by many PC makers for various reasons.
