Audio does not work through Remote Client

Usage Example:
When selecting Audio through the RMS , the number selected corresponds to the Camera which you want to hear audio from.
Camera 1 has audio channel 3 associated with it.
Through RMS , you select the Audio tab and the number 1 (for the camera), not number 3 (for the audio).

If problems still persists:
Attempt to get audio using a crossover network connection directly between a PC and the ETM DVR

Known Issues:

• The ETM-120-04CDRW, firmware version 1.23 or lower
  • This version only supports audio over a local network. Audio does not work over the Internet.
