I recently tried to play some .mkv files on my WD TV live player, but the AC3 audio is not playing (despite it being recognised). The video and subs work fine.
This happens only when the mkv files have been through the mkvmerge program (muxing in the subs for example). Even selecting a .mkv file that works fine, and remuxing it with no changes to the streams/file using mkvmerge gives an output file which causes problems with the WD TV. Strangely, everything is fine when I play the file in WMP 12.
Has anyone else experienced this issue? Is there any workaround?
