Pls help. Dxtory wont record any audio at all...(Both my In-game and microphone)

[ChrisIsNotMyName]

So the other day I got dxtory and tried it out for a while. For the first day, it worked out fine and was recording the video and both my mic and in-game sound. About a day ago I experienced some problems with the video cause when I view it, I could only hear sounds but I could not see the acctual video itself. I tried to change my video codec from Matrox to Lagarith lossless codec and it fixed the video but screwed up with the audio. Now I am stuck with the video but no audio. When I try to put the recording to sony vegas pro, the audio track just has a flat line on it. Any tips on how to fix? *Sorry for bad english*
