The sound system I used in the UK is no longer convenient, due to the TV-over-IP unit having no audio output other than that on the HDMI signal, and my amplifier being old school stereo using baseband audio. At the moment I am taking audio from a headphone output socket on the TV which is less than ideal.
I have the following video/audio sources, all with HDMI outputs:
IP TV 'receiver'
Humax DTT receiver (kept for the material recorded over the years) which also has analogue audio
DVD/CD player which also has analogue audio
a selection of computers, all of which have HDMI but also analogue outputs on headphone jacks
Two approaches come to mind - either an HDMI switcher with an audio separator which can drive the amplifier directly, or an amplifier which incorporates at least four HDMI inputs and is capable of selecting any one to both the TV via HDMI and driving *stereo* loudspeakers (not 5.1 or 7.1 bollocks thank you. I spent too long as an audio studio designer).
A potential nice-to-have may be an adjustable audio delay so that the layers of switches don't bugger up the synchronisation - an issue I have had previously.
I have located a couple of HDMI switchers; they're not expensive, but the reviews seem to suggest that they're also not particularly reliable. And to be honest, I'm not even sure what to search for for the amp - AV amp perhaps? I dunno. I do, though, want something which works *without* connection to the interwebs.
Any suggestions/advice gratefully accepted, thanks!
I bought an Onkyo AV amp well over 12 years ago, it has 4 x HDMI inputs as well as digital audio and analogue inputs, I use it to output to 5.1 speakers (ahem) but bought the two main speakers on account of their sound when playing good old fashioned stereo, plus looks (they are rather large , so need to look good too). Is there a German equivalent if Richer Sounds or Sevenoak HiFi you can go and visit?

To be fair - I did professional audio - at an order of magnitude or two more than I would ever spend at home. I never had much of a clue about domestic audio, apart from a few hours in a shop in the nineties where I upset the sales assailant by insisting on testing quite a lot of amplifiers with quite a lot of speakers - and discovering that he had no idea... he couldn't hear a phase error, and more particularly he couldn't heat that one of the amps he was trying to sell me was clipping the power rails...
I've still got that amp - a Pioneer A300 - and the speakers - Wharfedales. Both have performed sterling service.
@DaveG - I don't know, I'm still looking for von Richter sounds, but not come across them yet. Visiting isn't going to happen any time soon, courtesy covid.
Indeed my Pioneer VSX922 that I bought last year is 2nd hand and it replaced a 25 year old Aiwa AV (pre HDMI or anything like that) amp that decided it wasn't switching on anymore. The Tannoy's are still going strong... I love them. Certainly worth reading up on the VSX922 or others from that range.
I had this, when I was running an amp without any HDMI, but had multiple HDMI sources into a projector and running the audio through the 3.5mm jack. Not sure if this of any use, but can sell / post it to you for a nominal fee

So, stereo wise only, there are hdmi extractors, which give you rca-audio out. Then, there are toslink to rca adapters...Similar Bluetooth thingy available too. All pretty cheap. Then you can use the regular inputs of the amp. Then there are the multichannel options, I personally prefer Marantz, which, even designed for home cinema outperform many purely stereo amps in terms of sound quality. I'm in the diy process of converting old (and very dead) Technics cassette deck to just this - vintage looking, multi input stereo amp
The toslink mention came in mind because, as far as I know, all TV sets now have the optic output for sound bar, home cinema, etc..

Yes, I considered the optical tos-link - everything has that as an output except the computers, but then it needs a tos-link switch (and of course a copy-bit stripper! Not that I want to record anything, but I hate being told I can't...)
Oh, wait, I can use the tos-link out of the TV and route everything through the TV. Hmmm...
I fitted the splitter from Amazon mentioned above, and so far it's been flawless. The sound is somewhat better than that via the TV analogue output (presumably limitations in the TV's DAC or output drive) and infinitely better than the rubbish TV speakers... I wish they'd stop pretending that they sound good
Curiously though - live TV, recorded output from the Humax, and DVD from the player are all at the same level, but CD from the same player is perhaps 10dB louder on the few CDs I've checked so far. Perhaps they're just cranking up the volume on the CDs to use all the bits up...
I wouldn't be surprised. When I was doing that sort of thing, the rule of thumb was 12db headroom, 11dB quantisation noise, giving 73dB signal to noise ratio... but of course the s/n gets worse as the signal level drop. So crank up the volume, why not - pre-processing to make sure any peaks get compressed (and incidentally bugger the sound, but, hey, as long as it's loud!)
Certainly you see the dynamic range completely crushed on 'pop' style CDs, but I don't expect it on e.g. Deutsche Gramafon classical recordings.
But the explanation fits the observed facts: A DVD needs more headroom so Holywood can have its loud explosions, or to cover up the actor's mumbling with unnecessarily loud music...
This is what i have Its expensive but worth every penny - superb and does all my IR over CAT as well has HDMI i just keep everything away in a comms cab and can control whatever from whereever and use alexa also to do some voice commands such as Play CCTV in the Livingroom or Show DVD in the Family Room
I had the great good fortune of requiring yearly hearing and vision checks because of the BBC job. I know my high frequency response is no longer as good as it was - turns out that sitting in front of racks of tv monitors for years is very good at killing 15kHz and up - but Anita comments that playing the TV through a decent amp and speakers, and avoiding the reprocessing crap of 5.1 and the like - not only sounds better but enables her to hear the programmes more clearly (she has minor hearing loss and tinnitus).
Me, I spent so long in an environment where good quality sound was compulsory (including designing and building radio studios) that hearing the crap that passes for 'good sound' these days can be physically painful.
(But I still think that between 95 and 99.99% of what is spoken and written about 'hifi' is complete and utter bollocks )
