  1. No audio when playing HEVC videos using Windows Movies & TV


    I own a laptop capable of decoding HEVC (i7-8550U, MX150) . I have HEVC Video Extensions from Microsoft store installed. Movies & TV is able to decode x265 images, but no audio. Does anyone know how to fix this (I know I can switch to VLC or other program, but I would love to use native Windows program to watch movies).

    Directories with HEVC/x265 or Hi10p/10bit video sluggish

    This was working for me in the Anniversary Update and Creators Update, but has been slowly going downhill after the Fall Creators Update (build 1709). After updating to the Fall Creators Update, I could sometimes get thumbnails to show up in Explorer, sometimes
    not. I could sometimes get HEVC video to play in Movies & TV and Movie Moments, sometimes not. Now File Explorer won't create any HEVC thumbnails and HEVC video won't play in any of the Microsoft desktop or metro apps.

    Here's what I've been able to piece together from a couple of different sources:

    • Microsoft removed native HEVC support from the Windows 10 Fall Creators Update.
    • If you applied a feature update from a previous version (Creators, etc.), you were supposed to retain HEVC support. Wasn't quite true for me, which is how I found this thread. The work-around I mentioned in a previous reply has now stopped working.
    • Update KB4041994 enables SOME systems to ADD HEVC support back. There's a hidden app in the Microsoft Store called "HEVC Video Extension". Windows may add it manually. The app only enables HARDWARE HEVC decoding.
      You need a video card or processor released within the last ~year to get it though (Kaby Lake, Kaby Lake Refresh and Coffee Lake, and GPUs like AMD's RX 400, RX 500 and RX Vega 56/64, and Nividia's GeForce GTX 1000 and GTX 950 and 960 series.)
    • One of the sources suggests software HEVC decoding might become available as a paid app in the Windows Store in the future. No further info available.
    I did a clean install of the Fall Creators Update in Virtualbox. Applied all the updates and installed the "HEVC Video Extension" from the store. MP4 opens in Movies & TV metro app; HEVC video is blank, but HE-AAC audio plays. The slow folder refresh issue
    with HEVC files exists.

    I have a mid-range desktop processor and video card from early 2013. VLC plays 1080p HEVC using just a couple of percent CPU. I can encode 480p 30FPS in real time using the x.265 Medium preset. My system doesn't need hardware-accelerated encoding / decoding.

    As for the original issue. I took someone's suggestion and installed Icaros. Explorer refresh is speedy and I get thumbnails not only for HEVC MP4/MKV, but also FLV (like Icaros claims - anything FFMPEG can decode).

    Additional info:

    movies & TV app can't play sound in mkv files?

    Thanks, but - "Movies & TV" as it is now called is a Windows built-in App; it has a superior HEVC video codec which plays 4K h265 10-bit video more smoothly than latest VLC, Windows Media Player or Media Player Classic (aka, K-Lite).
    Unfortunately, the Movies & TV app gags on many audio formats - which ARE supported by those 3 other Apps. So - if I want sound with my HEVC movies, I have to put up with occasional freezes and dropped frames... OR - I may be forced to choose
    smooth playback - without sound! (Ms actually suggests using VLC to convert MKV to MP4, but it took 3+ hours on a reasonably fast laptop, to convert 1 movie & it was
    still was silent (in Movies & TV) after converting to MP4 file No audio when playing HEVC videos using Windows Movies & TV :) < Grrr! >

    (Btw, the MacOS version of VLC does play all of those 'problematic' 4K HEVC video files smoothly - with sound - and on a 6-year old Mac laptop.)

    No audio when playing HEVC videos using Windows Movies & TV

    DTS audio is not playing on Movies&Tv

    Hi Abdul,

    A DTS audio file format is not supported by the Movies&Tv app which is why you're unable to play it. To better assist you, we suggest that you visit this

    link
    . From there you'll see all of the file formats being supported by the Movies&Tv app.

    Hope this information is helpful.
