Yes: composite video doesn't carry audio at all. Your VCR has
either mono or stereo RCA audio output jacks, and you can plug
them into a stereo RCA-> 1/8" stereo headphone plug or adapter
cable to bring it into your sound card. Possibly your video
capture card has a separate jack for that?

Input 0 is probably RF-frequency NTSC with a tuner to select
channels. That's low-quality, but includes audio.

Input 2 is S-Video, which is the best of the available video
connections if your VCR supports it. (I have one that does... if
it still powers up.)
