Does anyone know how to synchronize speech and game sounds?

    This is a problem I've been having since my old computer died. My new one is more powerful but has only 1 sound card. I'm trying to make it so that when I record my voice on my videos, it records the game sounds too, at exactly the same time.

    Unfortunately, I haven't been able to do so now. Every time I try, my voice gets cut off as soon as I start the game. Does anyone know how to fix this problem?
     
    Here's the problem with Audacity.

    I have a video capture program called "Fraps". That records the game sounds as well as video. Even if Audacity DID capture my speech, the timing would be off, which is exactly what I don't want.

    Audacity doesn't let me record sound if another program is doing that already.
     
    I tried that with Windows Movie Maker. The audio comes out wonky. One minute the audio is perfect, the next it plays 3 seconds after it's supposed to.
     
    It's all right. I don't know if my computer is built for speech and audio at the same time. It only has one sound card. My last one had two, before it broke down.
     
    It's Sony's primary brand of laptops... this particular model's all about being able to watch BluRay movies on the go. Audacity'll let my overlap my mic sounds with the sounds my computer makes, if I set it up right (involves a couple cables).
     
    My desktop's a Dell and my laptop's a Toshiba. Do they have any sort of thing like you're talking about, soundwise?
     
    Sony laptops are bad, but if you want to buy Sony software (Vegas, Acid, etc.), go for it. Cost is through the roof, though.

    Anyway, what I'd suggest is to do what you were doing initially (dub your voice over the audio), check to see whether the timing comes up long or short, and then just stretch or compress the audio to where it times correctly. I've actually done this with a video I made for my friends.
     
    What I meant by overlapping with Audacity was to record the game audio by using a single wire audio cable to connect your headphone jack and your microphone jack, then unplug the cable and record your voice audio over the game audio. That's what works for me, though I can't guarantee great sound quality.

    Or you could try what twocows suggested.
     
    I'm assuming you want to do something like record game Audio/Video with real time voice chat through something like Ventrilo or TeamSpeak, correct? If this is the case, I can see the need for both to be recorded in real time. Unfortunately, however, it also tends to be very difficult to do without either two sound cards or one professional card with multiple inputs.

    In your case, the simplest solution would likely be to buy a headset you can plug in via USB. The USB connector, at least on some of the higher end ones, will act as a second sound card and you should be able to feed it's input and output to separate tracks in an audio recorder.

    Here's something else you could try if you don't want to buy a new headest. Get a 1/8 inch line cable and a splitter. You would need a male input split into one male and one female output - this may be hard to find. I'd look for you but I'm a bit short on time at the moment. Run the cable from your headphone jack into your splitter. Connect one end of the splitter to your mic input and the other to your headset or mic (assuming it is also 1/8 inch). Now, your mic will be getting audio from two sources at once and should be able to record on a single track. Then, just disable the audio track from Fraps and you should be good to go. The only concern here is volume balancing which would have to be done individually on the two sources before you started recording.

    There is one other thing you could check though and that's your Fraps settings. I haven't used the program myself but make sure it's not doing anything to speed up or slow down your game's audio or video. That could be a source of your timing issues.
