    Hi everyone.
    1. Does anyone know if we will be able to play music through miracast without also showing your screen (mirroring).
    Think: Streaming spotify from your phone to your stereo via the TV/Miracast device.

    If yes.
    2. Will we be able to show album arts and the tracks progress?
    3. Will there be any way you can skip tracks with a remote connected to the miracast device.
    4. Is there any metadata-stream in the miracast stream so that you can send volume-information. You send the music-stream in full volume (not loosing any quality) but send information to the receiver to lower the volume during the DA-conversion.
    5. Are there any lossless audio-option in the stream to use if the music-streaming-service doesn't use any of the other compressed codecs.

    In short: Can miracast replace airplay regarding musik quality and functionality, or is it optimized for video streams.

    I'm an audio nube, but wouldn't it just be easier to use a Bluetooth connection? does the audio quality suffer that much? if not, I think it would take care of most of the things your looking for...

    To OP, Miracast is video first and audio second. So you MUST mirror video. In fact most Miracast adapters only come with a HDMI port.

    Miracast is not for media streaming, what you need is DLNA (media streaming).

    Hi everyone, thanks for your answers.
    rory753: Windows Phone lacks support for bluetooth/apt-x protocol. That means that Windows have to decompress and recompress the music. Using compressed 320Kb/s music on a 4000$ Bang Olufsen system is bad enough, but dubble compressed is not OK.
    Different compression formats removes different things in the music, so their faults adds up.

    foxbat121: HDMI contains a few lossless audio formats and can be used for high quality audio. Its OK to use HDMI, you need a HDMI cable to be able to show album arts etc to the TV. Apple TV uses HDMI for example.

    Xpider: DLNA would work, bute there are no native DLNA-support in WP. There are a limited DLNA support in Xbox Music for Windows, but can not be used for protected music, only MP3:s. Still you need every application to handle DLNA-support separately, which will never happen.

    Apple TV is simply an Apple's rip off of DLNA, nothing more.
    Miracast requires the hardware support from the video chip to compress the entire screen buffer of the video output into H.264. Then use WiFi Direct to send the video to receiver. So, it is highly unlikely you will be able to get anything other than screen cast unless your phone has dedicated video chip for compose off the screen contents and send over Miracast (not to mention the separate drivers and software).

    So, for your purpose, DLNA is the best choice but as you mentioned, there is very weak DLNA support in WP. However, DLNA can be directly supported by the apps, no need for OS level support.

    Hi Foxbat
    All I care about is how I and other newly WP-users can get the same or better experience then when we had apple/airplay in our homes.
    Airplay works for video, music, screen mirroring and are part of the OS's API.
    DLNA works for video and none DRM music, but are not part of the OS's API.
    Miracast works fr video and mirroring and are part of the OS's API.
    Airplay contains more functionality than DLNA and Miracast together. If it is a ripoff, who cares if it based on different code and gives more functionality?
    The car is a rip off the horse wagon with its four wheels. Nobody complains about that?

    For me the solution will be the following.
    1. Wait until Spotify releases a full featured client for WP with spotify Connect and use that for streaming music to a Spotify Connect-enabled device like Bang Olufsens Essence or Xbox One (if Spotify releases a client for that.)
    2. Use miracast for videos land screen mirroring.

    Hi,

    I'm looking at the microsoft miracast wireless display adaptor v2.

    As I have a monitor (with an hdmi input) with very small internal speakers, I would want to use the microsoft
    adaptor to mirror my screen, but be able to send the audio - via bluetooth or cable - from my computer / surface pro 2
    to decent speakers.

    Would it work? Any suggestions? thanks

    Yes it does work, what you have to do to set it up is right click on the volume button on the bottom right of your screen and click on playback devices. Then you would click on the speaker that you want and then press set default. This will make it so that whenever that speaker is on and connected it will autimaticly send audio there.

    You could try HDMI Audio Extractor Splitter to SPDIF RCA Stereo L/R Analog Output Converter LE | eBay and just not plug anything into the HDMI OUT port. You might get the sound but as for albumart and whatnot on your tv screen, you'd have to connect the cable.
