Article: The Complete Guide To HiFi UPnP / DLNA Network Audio

You have to go through a powered USB hub to get iPads to talk to an audio device these days. I don't have time to look up the spec, but Apple changed the requirements (or should I say realized that they were not querying the USB device per spec standards in the first iPad iOS) about 5 months after iPad gen one came out.

 

Superdad, were are you getting your info??? because it's not correct!

 

First it has to do with the current draw of the device. All USB devices declare their current usage from the 5V VBUS. If they exceed the usage from an IOS device it will require a powered HUB.

 

Software wise the IOS devices have (and always had) the same capabilities as the OSX partners. They will require with some usages the Apple Authentication Protocol to work correctly.

 

Thanks,

Chris,

 

In my experience there are a couple of problems with DLNA. The first seems to be at the Control Point recognizing and understanding different audio file types. This seems to be the biggest problem. I will bring up a Control Point app and it will see like 1/2 my files on my full server. The other is the format for which the renderer tells the server to send the data or the servers ability to decode the output to the correct format.

 

There seems to be a need for an updated specification and nobody is really running with the ball right now.

 

Thanks,

Gordon
