I have no sound card on my machine, but I want to (automatically) record screen with audio on it. So I thing it's some kind of virtual sound card driver needed to loop back sound send to play to microphone. Is there such solution for Windows OS?

+1 This is one weird question. Nice, but weird. – alex Oct 15 '09 at 6:21
Virtual Audio card (Lakeofsoft) unfortunately does not seem to work on Windows 7 64 bit – user115470 Jan 26 '12 at 17:02

"Virtual Audio Cable" costs $30. I guess you can buy a cheap audio card for that price. – Snark Oct 15 '09 at 5:21
There is a free trial version limited to 3 virtual cables. This may be enough for artem.tikhomirov – user12889 Oct 15 '09 at 23:21
Thank you very munch. That's exactly what I need. – Artem Tikhomirov Oct 16 '09 at 10:29
@user, the trial version has a voice saying “trial” every fer seconds, so it's not actually very useful – svick Nov 19 '10 at 12:59
There are also other similar drivers, like VSC (which seemed to have better pricing for our purposes). – svick Jul 19 '11 at 15:58

A cheaper virtual sound card with the same function.

Also includes a virtual webcam to broadcast/record screen/file. May consider the virtual audio+webcam package.

Actually, it's currently only 5 cents cheaper. – svick Nov 19 '10 at 13:11

possibly of interest:


Virtual Audio Card

It's free and it works on Windows XP and it creates 3 Virtual Audio Cables as Windows Sound drivers.

It comes from a software kit for a commercial TCP/IP mp3 streaming device. Go figure. Works for me in place of VAC (Virtual Audio Cable) but the latency on my machine is pretty awful. YMMV
