[Trisquel-users] Re : Envy 24 sound card issues.

I find that depending on the track certain media players play MKV files  
without sound, VLC being the exception. I assume the other players use  
similar codecs (e.g the GStreamer codecs). I find using Mplayer then looking  
at its error messages helped to identify what extra packages were required to  
get it to work.
