Windows Vista changed the way Windows handles audio. Before Windows Vista you had audio lines coming from one unique device. After Windows Vista each audio line became an audio device.
The first thing to do is to right-click the mouse over the speaker icon that sits on your system tray and select ‘Recording Devices’, then inside the recording devices panel right-click the mouse over again and select ‘Show Disabled Devices’. At this point you will see all recording devices you have installed.
Didn’t you ever try to record video with audio or only audio and you get an error depending on each program and you keep asking yourself why is this error happening? Well, in most cases it is simply a matter of turning the audio device into the Default device.
So, whenever you get an error while trying to record audio or video
and audio do this: Right-click the mouse over the speaker icon on the system tray, and choose ‘Recording Devices’, then make sure the audio device you have set on the recording program is listed and enabled, if it is not Enabled then enable it, and most importantly make it the default device.
To turn a recording device to be the default device you have to select the device and then click on the ‘Set Default’ button.
That is it. This simple procedure has a good chance to solve your recording problems. But before you go through all this trouble, try to record video without audio on your recording app, if it succeeds then you know for sure that the problem is the audio device.
There is one more thing: Some audio devices come with special effects and boosting options, turn them all off otherwise recording programs can’t manage to work with the audio device. This is the case especially with your microphone device or Line-in device.
This is a short article that hopefully will be able to help people having audio video recording problems on Windows Vista, 7, or 8.
