I have an old webcam in my porch which enables me to see who is at the door when I am upstairs on my PC. I put it in about 7yrs ago and it works well via a 6Mtr screened USB cable. The camera is also capable of audio although I have never used it for that. It is called "ICatch (V1) PC camera" and I am using Amcap software which shows a heading "Sunplus SPCA 561". I would now like to enable the audio but have failed to do so. A bit of a longshot I know but if anyone can help I would appreciate it.
