    Hi,

    my first original Max2Play squeezeserver/jivelite/7inch PI touch is working perfectly, connected wired to my amplifier.
    Youtube videos I can watch on my Ipad and playing the audio on my Max2Play Pi via sharepoint.

    However, I‘m looking now to stream also the video signal wireless from my ipad to an external beamer, but the audio playing seperated as used via the first max2play pi…

    Ho to do this? Any possibility via e.g. a 2nd max2play pi, HDMI port -> external beamer?

    Of course audio and video need to be synchron.

    Hi lemuba,

    Should work with Kodi -> System -> Service Settings -> enable DLNA or AirPlay -> stream video stuff

    I just tested with RPi3, Kodi 17.4 and UPnP/DLNA via Android using AllConnect, should work the same with AirPlay, your device shows up as „max2play (kodi)“

    Hello Heiner,

    thank you! I will test asap and report back.

    Hi lemuba,

    Just to clarify, you need to connect one Pi via HDMI to the beamer AND the sound card on the same Pi to your speakers. Then, you can select the audio output for your sound card in Kodi and have the HDMI output be to the beamer. That should allow your setup to work with just one Raspberry Pi.

    Hello Heiner, then it will unfortunately not work for me.
    Sound needs to come from PI 1, Video via HDMI from PI 2.

    My plan was to mount a budget LED beamer together with Pi2 to the living room ceiling and to stream wireless e.g. youtube video to it. But the sound needs to come from the Pi1 which is connected already to my 1980th amplifier and the sound output to two speakers mounted in the same ceiling.
    Defacto I need an extended Multiroom Video and Audio Solution…

    Hi lemuba,

    For that you could try pairing your device to play youtube on with the bluetooth plugin for the audio Pi and stream the same procedure as mentioned above for the second Pi with video.

    I got it now – I reanimated my old AppleTV2 with direct video output via HDMI to the TV or Beamer and updated it to the latest firmware. It the AppleTv menue its possible to select again external AppleTV speakers — in my case Max2Play via sharepoint. Video streaming from our IOS devices via airplay is now working almost perfectly — with almost I mean:

    — The Video/Audio sync is almost perfect — the audio signal slightly delayed, but almost not recognizeable…maybe approximate 0,1 seconds.
    — I miss a working volume slider on the IOS device — the volume of the streamed video content can currently only be adjusted manually on the amplifier. On the AppleTv I set up one times the external airplay speakers volume (Max2Play) to maximum. But according to my knowledge yet, it is not possible to adjust the volume during streaming on the IOS device…tbc, to be optimized…

    Hi lemuba,

    Firstly, congrats on finding your own solution.

    Secondly, if you have not yet, you can add hardware volume control for shairport which is exactly what should fix your volume issue:

    Hello Heiner,

    the hardware volume control is not working yet – I believe it´s a mixer related issue – any idea how to fix?
    My soundcard is from your bundle (7# touch display, PI 3 and IQaudIO PI-DAC+)

    I used following command line in the extended shairport options:

    -t hardware -m hw:0 -c Digital

    Error Message:
    Versucht zu starten … NICHT Erfolgreich Hier klicken für weitere Informationen
    The alsa backend -t option is deprecated and has been ignored. FYI, using the -c option automatically chooses a hardware mixer.
    Failed to find mixer element

    amixer output:

    Hi lemuba,

    Since you have an IQaudIo Pi-DAC, the shairport player should automatically be set to ideal hw volume control when selecting the sound card and rebooting. Please try selecting none as a sound card, rebooting and selecting the Pi-DAC again and rebooting.
