Quiet Audio

[zultan]

Hi, I am currently running Mezzmo 2.7.1.0 with a pair of WDTV devices. Recently I've noticed that I need to increase the TV volume considerably to hear anything. Dialogue is particulary quiet. The problem does not occur with my FLAC files, streamed to the same devices. What should I do?

What is the FFmpeg information on the the video that has the quiet audio? To get this, right-click on the file in Mezzmo and click 'Get FFmpeg Information'. Also, make sure you using the 'WD TV Live' device profile for your WD TV Live devices. Go to the Media Devices dialog to check this.

Thank you for your prompt reply. WD TV Live (Gen 1) is correcly selected as the device profile. Here is the FFmpeg format:
