DO i need some extra hardware interface for receving both Audio and video

Question

hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for receving both Audio and video. im using code AVTransmit and AVReceive found from this site only
After running TX
i give Dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull
transmiter/server side code .first run TX on server

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works
