    Default HLS stream without audio on iOS

    Hello,

    HLS stream works well on Android but on iOS only video works without audio.
    Do you have any clue why is that?

    Regards

    Hello there and welcome to the Wowza support forum.

    What type of stream is this? Live or VOD?
    What is the audio codec of the stream?
    Do you see any indication of this issue in the logs? You can start Wowza in stand alone mode [install-dir]/bin/startup.bat|startup.sh, and view the output in the console.

    Kind regards,

    Salvadore

    Both Live and VOD. Android works well but no audio on iOS.
    We use default audio codec. We don't change it. I think it's Speex. (We don't use multibitrate.)
    No errors in logs.

    Any ideas?

    iOS devices only support MP3 at 44100Hz, 128kbs and AAC audio. You have to transcode the Speex to AAC. Take a look at this guide:

    Kind regards,

    Big thanks. It works!

    But only for Live. Is there any way to have audio on mobile during VOD?

    For VOD, you will need to implement a 3rd party solution. Please take a look at this article on How to encode video on demand content.

    Kind regards,
