    Default Chromecast - audio compression

    When trans coding mkv files the audio compression is to hard, resulting in bad sound quality. Can the device profile for Google Chromecast be modified to improve sound quality?

    sent you an email about this too.

    Video with MP3 or any other 2channel audio seems fine but once it decodes surround the bitrate goes back to the dialup days to the point I can hear artifacts in the background.

    I suspect this is due to a bandwidth restriction on the heavier 5.1 as opposed to the smaller 2channel?
    Any chance you could optimize this profile to downmix all to 2channel? as I just have it as a simple bedroom TV setup.

    Thanks in advance

    Email us at support [at] conceiva [dot] com and we'll tweak the device profile for you to try. In your email, describe the problem in detail and include FFmpeg information for video that you can hear audio artifacts when streaming to Chromecast dongles. Right-click on the video in Mezzmo (Windows) app and click 'Get FFmpeg Information'.
