Before proceeding, reformat the microSD card in your ContourROAM using the steps outlined here and then test your camera's audio. In many cases this will correct the low audio issue.
We recently discovered some early production ContourROAM camcorders are not recording audio correctly. The resulting audio may sound very low or non-existent when played back on the video file. We determined there are two separate issues contributing to this “low audio” issue – an intermittent low audio condition that is resolvable with a firmware update in the field and constant low audio condition that cannot be resolved in the field.
The intermittent low audio issue is firmware related and involves the Automatic Level Control (ALC) for the camera’s microphone. After being exposed to a loud noise, the ALC will temporary dampen the audio levels for an overly extensive period of time. Cameras with firmware version 1.06 will NOT exhibit this behavior and the audio level will quickly recover after the camera is subjected to a loud noise. If your camera is experiencing intermittent low audio as described above, please check the firmware version on the camera and upgrade the firmware if necessary. The firmware download and complete firmware installation instructions are found at: http://help.contour.com/customer/portal/articles/235034-contourroam-v1-06-
Once this firmware is installed, the ALC will work as properly and return the audio level to normal much quicker after loud noises. Please contact Contour Technical Support if you have any questions.
The second audio issue involves the camera CONSTANLTY recording low audio. This issue is the result of a mechanical problem with the camera’s microphone assembly and cannot be corrected in the field. For customers experiencing this issue within the US, please contact Contour Technical Support directly (http://help.contour.com/customer/portal/emails/new). Contour Technical Support will make arrangements to get you a replacement camera that does not exhibit this issue. For customers outside the US, please EXCHANGE your camera at the local retailer within your country from which you purchased the camera.
Thank you for your patience and understanding.
