Youtube - video on Ipad + audio on Uniti - how?

You can do this with an Apple Airport Express - even the older ones. They only receive audio so the video plays on the iPad screen whilst the sound is sent over AirPlay to your Naim system. I got a couple on eBay for exactly this purpose.

You will suffer pretty poor audio sync issues. for my money I would hook up an apple tv to the tele with digital out to the uniti, you can airplay mirror the screen to the tele then

In my experience the Airport Express does exactly what BR is after, without sync issues or lag. The Apple TV would also do the trick though, and of course gives you the option of mirroring the display onto a connected TV too, as gari says.

Thanks for the solution first. Do I understand it right: I get the youtube

video+audio on the ipad, send (how?) the audio to the airport express device

and this acts as server which my naim can use as source. ok?

The apple airport express acts as a dlna server. Why cant I send from my

ipad directly to the naim, means the ipad needs a kind of dlna app?

Would save an extra device.

BTW: even with a cable I have a delay between video and Audio on the naim

(might have been a bug in the video itself, too).

You send the audio via AirPlay from the iPad to the Airport Express (easy - just swipe up from the bottom of the iPad screen and select AirPlay). The Airport Express has a simple audio out (combined analogue and optical 3.5mm jack) which you use to feed either an analogue or optical input on the Uniti using the appropriate cable. So once your hardware is set up the process is:

play YouTube video on iPad

select AirPlay -> Airport Express

selet appropriate input on Uniti

adjust volume as desired

enjoy

I use this setup myself in various rooms around my own home and it works perfectly, with no lag or video/audio sync issues.

Note that the Airport Express does NOT act as a DLNA server - I'd suggest reading up on this to avoid any disappointments. As far as I am aware the only way to stream audio 'live' and wirelessly from an iPad is via AirPlay or by using a third party dongle, which is a less convenient option and would cost more than an Airport Express. A second hand Airport Express from eBay, even the earliest generations, is cheap and will do everything you need.
