    I started a thread on this topic on the old forum.  Luckily I kept a copy of the first post – here it is:

    As one of several Beoworld members routinely connecting modern AV sources (eg Apple TV4) to older B&O TVs (i.e those without an hdmi input), I thought I’d post my experience with a few hdmi Audio Extractors.

    In short, most people in my situation will want to feed the Apple TV’s digital video signal to the TV’s digital DVI input, which usually works (as long as there are no hdcp problems).  However, DVI does not carry audio hence you need to use an hdmi Audio Extractor to extract the audio signal and feed it into the TV’s analogue PC sound input sockets.  Of course this sound will be stereo only.

    Audio Extractors are mostly small devices (approx. 6x6x2cm), and tend to be supplied with a simple USB power lead – you are expected to find your own power supply.  I usually use a spare iPhone charger to provide a suitable 5V USB output.

    Anyway, several years back when I first purchased my Apple TV4 and wanted to connect to my BV6-26, I used this Audio Extractor: https://www.amazon.co.uk/aoeyoo%C2%AE-Analog-Converter-Digital-Extractor-White/dp/B00NAJ4UM2

    My Apple TV4 is what is now called the HD version (not the 4K version) and as an aside I have contributed to madskp’s thread about using the the Siri remote with B&O here: https://forum.beoworld.org/forums/t/34673.aspx?PageIndex=1

    My Apple TV and the Audio Extractor above were initially used with my BV6-26 Type 9272 which has a DVI socket.  The Audio Extractor worked very well, hence I have recommended it frequently in Beoworld discussions.  I also purchased a second to use with my BV6-23.   I found that Apple TV’s video output setting worked well at ‘720p 50Hz RGB High’.  My only negative observation is that the audio LR channels are reversed in one of the two Extractors  – easily corrected by swapping L&R phono connectors at the TV’s PC sound input.

    However, I recently ‘upgraded’ to a BC6-26 Type 9282 (with both component input and DVI socket), and tried to use the same Audio Extractor setup.  Whilst watching I noticed occasional blinking of the screen – not all the time, and not frequently, but enough to be annoying.  I suspected a timing/synchronization issue.  I experimented with several different hdmi leads (from ATV to Extractor) and hdmi to DVI cables (from Extractor to B&O TV), and tried different power adaptors.  I also tried different Apple TV video output resolution settings.  None of these experiments removed the ‘blinking’.

    Hence thought I’d experiment and tried a new Audio Extractor, eventually ordering the following:  https://www.amazon.co.uk/gp/product/B07TZRXKYG

    My thoughts were that this new Extractor would be configurable to suit various input and outputs, and would work with my setup.  However, when the Extractor arrived I found it very difficult to setup – there were just too many permutations of the little DIP switches on the side.  I found that I could get video and/or audio outputs working but not reliably, and there was occasional video interference (lines across the screen).  Also there seemed to be an annoying background hiss.  The instructions were poor and I could not get the Extractor’s reset button to do anything.  It cost about £28 and didn’t work (or wouldn’t for me) so I sent it back to Amazon for a full refund.

    This week I have purchased a further ‘Amazon Basics’ Audio Extractor for about £15:  https://www.amazon.co.uk/gp/product/B07KRWYN4R

    This worked very well straight away!  Although the instruction manual said that 720p 60Hz was supported but when I tried this setting my Apple TV seemed to auto configure its resolution back to 720p 50Hz and continued to work very well.  The sound quality is also good with no noticeable hiss.  Note that this Extractor also has a digital sound output, although I have not tried this.  This Extractor is also very well built with a strong metal case and good quality connection sockets.  I am very pleased with this latest purchase.

    Perhaps if other Forum members have experience of other hdmi Audio Extractors perhaps they could post here and let us know how well they work (and with what sources and B&O equipment).  If using Apple TV it would be useful to know what video output resolution setting you have chosen.

    I hope forum members find this post useful – I will amend or update if I experience any problems with the latest Audio Extractor in the coming days.

    Have a good weekend all!
