Hi guys

Bought a new (black Friday deal) 4K TV on a bit of a whim - the Samsung 43" UE43NU7020K ( https://www.samsung.com/uk/support/model/UE43NU7020KXXU/ )
Great entry level 4K TV and still some mega deals on them. We upgraded from the fairly standard HD 40" UE40K5600AK ( https://www.samsung.com/uk/support/model/UE40K5600AKXZF/ ) which has served us well.

Part of that setup we have been using TaoTronics bluetooth headphones with (5600 has BT). The 7020 doesn't have bluetooth so bought a TaoTronics TT-BA09 ( https://wap.taotronics.com/product/...product/product_details?urlKey=ttba092afae1ab ) to connect to the Optical out and then transmit to headphones. Makes sense right? (Bonus - being able to use 2 sets of headhones too!).

Problem we have now is strange... Much of what we watch is streamed content - iplayer, itvhub, Now tv and more recently Chilli.tv (got a bunch of free credit from Vodafone). The 7020 doesn't play any audio through the BT headsets when using any streamed service, yet works fine on normal TV. I thought it might be the TT-BA09 but swapped back to the older 5600, plugged the TT-BA09 into the Optical and it works perfectly. Weirdly the TV speakers on the 7020 work fine on streamed content.

I'm at a bit of a loss what the fault is, it almost seems like a decoder/software/firmware bug in the Optical output from streamed content (yet 'normal' tv unaffected). I have nothing else Optical to test with it. The 7020 also doesn't have a 3.5mm jack out we could use instead.

Getting close to returning this 7020 while we still can! :eek::mad::o

Any ideas?! :confused:

probably need to get the tv's optical output specs ..
but maybe older tv only sends pcm via optical and the new tv sends a bitsream (for non freeview) of some kind that the ba09 cannot decode ...
can you force the tv to send pcm ?

quick google https://us.community.samsung.com/t5/TVs/Optical-audio-output-not-working/td-p/214630 similar'ish
"Well, I asked the same question in a local A/V forum and we came up with the solution pretty quickly. Nothing wrong with the DAC I was using, it's in the TV Settings. Sound > Expert Settings, HDMI Input Audio Format must be PCM instead of the default Bitstream. That's it for anyone encountering the same problem."
