This is AC3, not AAC...
How is your WDTV connected to your receiver/tv?

You mean the WDTV is set to stereo?

Yes, stereo.Meant AC3 too bad typo. It's connected via HMDI. I think I found out the reason something has changed in the .mkv codec where none of the WD HD players aren't able to read the audio without a firmware update..

If the problem is the same as the one in that thread, an easy solution is posted there:
Quote
If any of these files got encoded with MKVMerge 4.1 or higher, there's a good chance that they used "Header Removal Compression" (which is now DEFAULT) and none of the WDTV players of any generation support that.

 

Mediainfo can confirm.

ANY version of MKVMERGE will work.

 

Here's what you need to know, though:

 

Versions 4.0 and EARLIER do NOT use header compression.   So, with those versions, you can just load up the file and re-mux immediately.

 

Versions 4.1 and HIGHER DO use HEADER COMPRESSION by DEFAULT, but it CAN be disabled.

 

Load up the file.   Select the Audio Track(s).  Click the "Extra Options" tab (I think that's what it's called) and select COMPRESSION:  NONE.

 

Remux.  Done.   Total time:  A few minutes at most.
So simply remux the files without 'header compression'.

Thanks! That did the trick.  ;D

With WD stop supporting Gen 1 looks like the player is no good for new stuff anymore.. :-\
it only took a minute or two to remux the file, but still it's annoying to do from now on.

Yeah, but it seems like it's limited to certain groups/rippers that don't turn the compression off. I get new mkv shows and movies all the time and they all work fine...
Glad you got it working at least :)

Funny that I always recreate the MKV container with 16x9 in the video tag and inside Portuguese subtitle.

So I was never impacted by this problem.  :D

That is the problem of being perfeccionist like me. You always want things right!!
