NDX, iPad, and Smart TV

Posted by: John Toon on 03 December 2017

I have question please. I own a NAIM NDX and am trying to connect my iPad to a smart TV while viewing youTube and wanting to stream Audio via Bluetooth to my NDX.

I can stream Bluetooth audio of youtube while viewing the iPad screen no problem.

I can view the Youtube from the iPad via the smart TV no problem and audio through the TV. However, when I select NDX under airplay I can still connect to the NDX bluetooth okay and the NDX screen even shows what is playing on bluetooth (i.e. whatever I am viewing in YouTube, but for some reason there is no sound from my naim system.

Can anyone help please, or perhaps it is just not possible? Thanks in anticipation. John

Not sure if what you want to do is possible, but maybe you can connect the TV to the NDX optical input and route the sound that way. I’m not sure if this would work for Youtube, but it should work for regular TV viewing. Also, if you have a smart TV, it may play Youtube natively rather than having to route it from the iPad.

John, just played You Tube from my IPad into a Samsung QLED TV as wired above and this works.

Thanks for this, but not sure it is the answer. Ideally I want to be wireless so that iPad streams to the Smart TV, and bluetooth sound connects to the NDX. Strange thing is it seems to be almost there with the iPad screen coming up on the TV okay and bluetooth connection working with the NDX (including is showing what track is playing from the youtube playlist), but no sound So infuriating.

I suspect that an iPad is not capable of streaming to two devices at the same time (i.e. picture to TV and sound to NDX.) Is there a problem with connecting the TV to the NDX optical input?

No and I must admit I have not though of that. In his way can I then stream video and sound through the NDX and then onto the TV? Will give this a go and thanks Chrissu!

There isn't an optical output on the NDX but there is an optical input into the NDX...

No, as Phil says, it has an optical input. What I’m suggesting is that both sound and picture are sent from iPad to TV, then the sound is sent from TV to NDX. This would mean that all your TV channels would get improved sound quality by playing through your hifi.

I'm afraid I don't understand this - there's no way to stream sound and video to an NDX and then on to a TV ... that sounds like you would end up using the TV sound anyway if you even could do it.

You could stream video to your TV (which would include audio) and then use the S/PDIF out on the TV to pass the audio on to one of the NDXs S/PDIF inputs which would then play through your HiFi ... of course you'd need to ensure that the TV was outputting PCM (stereo) audio rather than bitstream (surround / multichannel) encoded audio as the NDX doesn't decode surround encoded audio in which case you'd get silence (at best) or digital noise (at worst).

Hi Phil, further update. Took your advice and although the TV defaults to PCM when you select YouTube either airplay or smart TV, you have to reset it as PCM. Possibly a quirk of my TV, but works great now and thank you so much to all the Team, and especially Phil.
