I recently purchased new in the UK a DVR4CHSOUH264 with Software 7.09.06 13D4E and Hardware Rev: 1.3 and now trying to get the audio to work. I have special CCTV microphones with preamps and when the audio is 'enabled' on the 'record' page of the DVR, they come out loud and clear with about a second delay, so putting the microphone near the speaker causes an echo build up. However, as soon as I escape from the 'record' page the audio completely stops working. I get nothing LIVE or RECORDED! It would seem from the above that the audio input and ouput is working o/k. SO WHY DOES THE AUDIO NOT OPERATE DURING NORMAL OPERATION.
