I'd like to use the input from an USB microphone and my sound card (some Realtek)'s Line In input at the same time - so that they could be recorded at the same time by a program (Audacity or Skype or any program which would normally expect only a single device).

Is there any solution for that?

I'm on Windows 7, 64-bit.

If the program supports multiple simultaneous inputs, then it should be able to read from both devices. Have you tried it already? Is there some error or something that’s preventing you? – Synetech Feb 5 '11 at 23:27
No, the program only expects a single recording device to be chosen. – Kos Feb 6 '11 at 11:53
