Sound Skips

Hi, I’m not very tech-savy but i’ll try my best.

First, my files are stored on a WD ‘My Book’ External HD connected via USB to my ‘WD TV Live Plus HD Media Player’ connected to my TV via HDMI cable.

  • current firmware - 1.06.16

  • The audio is set to Stereo on both the media player and the TV

  • The problem is all my video files with FLAC audio, the sound skips. I have only owned the media player for a week or so and this problem has left me disappointed.

  • Yes I have tried remuxing the file with MKVtoolnix

  • Ive tried the other audio settings but nothing changed

  • Also the first thing I did when I bought it was update the firmware, would rolling back to a previous version fix anything? if so what version?

here is the info on one of the problem files with flac audio that skip:

High @ L5 h.264 video decoding isn’t supported by the chip.  The chip can’t keep up with the video stream, is why your audio is suffering.

You’ll have to recode the files to something the chip is capable of decoding.


5. MPEG-4.10 (H.264) BP@L3 up to 720x480p30 or 720x576p25 resolution, including FMO and ASO.

6. MPEG-4.10 (H.264) MP@L4.1 and HP@L4.1 up to 1920x1080p24, 1920x1080i30, or 1280x720p60 resolution (constrained to match BD and HD-DVD specifications), 180 Mbin/s maximum for CABAC streams.


  • H.264 BP@L3 up to 720x480p30 or 720x576p25 resolution.
  • H.264 MP@L4.1 and HP@4.1 up to 1920x1080p24, 1920x1080i30, or 1280x720p60 resolution.

No firmware can change the chip’s decoding abilities… all you can do is provide it with supported streams.

thanks for the reply, like I said im not very tech-savy, im more of a ‘monkey see, monkey do’ type

im looking at the info on some of the other files that dont work and its strange because there are files with High@L4.0 that do not work, and yet some files with  High@L5.1 that work perfectly fine

Well, for that matter, the manual only lists the following audio formats as being supported in a Matroska container:

  • MPEG
  • PCM
  • Dolby Digital
  • DTS
  • AAC

Nothing really says that pulling FLAC out of a .mkv is supported by the WDTV, even though FLAC is supported in a FLAC audio file.

I probably should have started with that one. :wink:

But, I doubt you’re going to convince WD that it’s a “bug”, when they never claimed it’d work in the first place.  The stock answer we get is generally to play supported files.

There’s many things that aren’t listed as “supported” and yet they work anyways… or, at least somewhat work… but all we can really do is go to the Ideas section and ask for official support.

hmm, ok fair enough, thanks again for the quick reply, much appreciated.

Sorry I don’t have a happier answer for you.

In theory, since the chip itself can decode FLAC, I see no technical reason why FLAC (and OGG) support can’t officially be added to .mkv in a future firmware… but since they’re not officially supported now, nobody can really guarantee success with trying to use them.  It may work, or it may not.

I’m just so used to answering “my HP @ L5 won’t play properly” posts, that it didn’t even occur to me, at first, that FLAC wasn’t listed as supported.
