    That is of course true however of all Phillipeís excellent plugins upnpbridge is the one thatís least likely to work the way you want. Thatís no sleight on phillipeís code, itís the fact that upnp devices donít conform to any published standard and no two such devices quite work in the same way.

    To be honest in the setups I had been using upnp, I never had some kind of strange problem because of upnp anyway.
    Now ever since it is not necessary for the system to work I donít see a reason to use it.

    If you have an IP connected TV or Cinema Amp then you might find UPnP-AV as one way of having them join in.
    Of course, putting a player beside/behind the TV and connecting it up is another way ... or finding that the TV/Amp has Chromecast or AirPlay built-in brings even more ways.
    Basically there are numerous ways to do this sort of stuff nowadays.

    Personally I am interested in audio so all these features are good to know that they exist but no need for them ... for now anyway!!
    I am using a Chromecast though mainly for Netflix and YouTube

    Coming back to the thread..
    I saw that apart from UPnP there is also UPnP AV protocol.
    This is supposed to be optimized for AV applications.. no? Any comments about the differences to the "plain" UPnP?

    My question as I said before is that it seems strange to me that many expensive high end audiophile servers rely on this protocol and not squeezelite.

    UPnP is a family of protocols - and UPnP-AV is the family member used by the audio/visual industry.
    When your device - such as a TV - lists UPnP it almost certainly means UPnP-AV.

    The Squeezelite protocol is proprietary and published. It needs LMS server (or ~100% compatible) to be installed in the home network.
    Most homes do not have one.
    Some NAS (file servers) have it - but many more have a UPnP-AV server (such as Twonky) or the one that is built into MS Windows or perhaps Plex.

    I see... Thank you for clarifying.
    And now the question is apart from features that obviously there are many and different to each approach.

    What about sound?

    Also UPnP needs MPD for reproduction of sound yes? Is there any other way that does not use MPD?

    In broad terms ... it is the same bits that are transmitted to the device that is playing the audio.
    Provided the rendering device can support the codec/bitrate etc.
    The LMS set-up (including with plugins) is more sophisticated and can do a good job in handling all sorts of source files - and transcoding them if needed - and syncing playback devices ... which it can also do if the player is using UPnP-AV.

    Not really. There are plenty of different UPnP-AV "renderers" (players).
    For example - see non-exhaustive and long list at
    https://en.wikipedia.org/wiki/List_o...layer_software
    Internet-enabled TVs/AV kit/Hifi often have UPnP-AV renderers built in.
    However, while the specification is a published standard and large it also has a lot of options. One thing that we know from standards is that where there are a lot of options there can also be interoperability issues even where there are basic profiles.
