No Audio Stream through DV Cam to Firewire Issue in Connect Pro

Report · Mar 28, 2011

I have seen a few other forum posts on the issue but none has helped thus far.

My setup is a Sony DSR250 near broadcast quality DVCAM that gets sound from a Shure Mixer connected to Lavalier Microphones. From the Camera I go fire out to the laptop (a IBM/Lenovo T1500) and currently I have to use a 3'5 male jack plugged into the laptop microphone input to get sound.

I am trying to get the audio to stream in from the camera firewire connection. I have downloaded DVDrive and I got the video stream to come through but still no audio. I went to the sound setup and it only detected the on-board microphone and the microphone jack when I believe there should be a DVDrive or DVcam input.

Does any have suggestions for getting the audio and video to come through the same stream via firewire. And in case some one raises the issue I am positive the camera is getting sound from the mixer since I can see the audio levels on the camera.

Your problem is stated on the DvDrive website:

"DVdriver does not support audio. You might be able to do what you want to do by selecting DVdriver as the video source in your video-conferencing application and selecting your camcorder as the audio source if the video-conferencing software allows you to select separate devices for video and audio."

Adobe Connect uses Adobe Flash as it's base feature set and where it gets it's audio and video feed. Adobe Flash can see your video devices through the operating system driver which in your case would be DvDrive. If DvDrive is not supporting audio transmission, then Adobe Flash would not be receiving audio and why you are having this problem.

I was able to locate the Sony manual for this camera and I read most of it. I see references to the iLink cable. That is Firewire for sure. However, I see no reference in the manual to PC/Mac based support for this camera. I see all kinds of references to this iLink connection to a VCR. So, when I see this it tells me that Sony did not intend for this camcorder to be used with a computer and they did not engineer it to work with the native Windows and Mac drivers for digital camcorders. Consequently, that is the issue. Adobe Flash will only work with cameras that are supported by the operating system. Now, that being said, if you can find a driver that will work properly with this camera then Adobe Flash and Connect will work with the camera. It looks like the choice of using DvDrive is not a good one since they do not pass on the audio. I'm not aware of additional drivers in the market, but you need to find one that supports transmission of both audio and video at the same time.

I hope that helps.

Try using Xsplit instread of DVDrive. Xsplit supports both video and audio as well as you can do a lot more things with it like PIP, etc. I use it and love this application. Xsplit will present itself as a video/audio driver to Adobe Connect. You can download a trial version here
