Cannot replay recorded video


If the audio is closed on Symphony Client, the recorded video can be replayed, but if audio is turned off, then the recorded video replays for only 5-10 seconds.

The following errors appear in the Client log:

Error Failed to connect to input pin on filter 'Axis Audio DMO Embedded': 8004022A
Error Failed to AddAndconnect Axis Audio DMO Embedded
Error Unhandled media type: {000002EF-0000-0010-8000-00AA00389B71}, trying AVI Decompressor

Probable Cause

Some Axis DLLs were not registered.


  1. Ensure that Axis software is NOT installed. If Axis software is installed, then uninstall it from the computer.
  2. At the command-line prompt, enter the following:
    cd C:\Program Files\Aimetis\Symphony\_bin
    for %a in (*.ax *.dll *.ocx ax*) do (regsvr32 /s %a)
    killall 9
    killall 5
  3. Restart Symphony Client.
