Try check if the audio stream of that movie is AC-3, and if so then try use mpv with the option --ad-lavc-ac3drc (read the man page for valid values). If you experience similarly expanded dynamic range also for differently encoded audio sources then more likely there's a problem in how your system downmixes multi-channel audio (like deloptes is getting at). NB! Consider switching to mpv in general, it is a successor to mplayer with many improvements. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
