Title: Anyone else do this?
Post by: ScottulusMaximus on November 08, 2018, 11:26:34 AM
So after ditching the AVR set up and going back to stereo I had to come up with a solution for the Shield and Nintendo Switch sound to get into my Karel mars pre-amp, so I got myself and HDMI ARC DAC(that's a lot of acronyms) so I could use the TV as the switching component:

https://www.amazon.com/gp/product/B07DWLMWHQ/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Now this worked fine but intermittently the ARC connection would drop requiring the TV to be unplugged to power cycle it which drove me mental.

So I got thinking and researching and discovered most, if not all, modern TV's still have an optical out. And most, if not all, decent DAC's have an optical in. So why not try that! Got myself a Cambridge DAC magic from ebay.co.uk and now I can have a decent digital experience paired with a completely separated analog setup in the same system!

Quite proud of myself actually...

I find ARC more of a hassle than anything else myself as well, just stick with optical out. The other useful aspect of using optical is it's a good way to sync the picture with your sound solution as usually it allows you to play the audio through both. Just play the audio through both at a matching volume and adjust delay until they sync up (also a good way to figure out input delay).

Yip. Thats how I connect my laptop to my stereo set up, as my preferred dac has no USB but has optical. I also cast from my cell to my tv and thus can use the dac in the same way.

did the same for a while. optical out into fiio d3 usb powered dac - 599 from cplan & 24/192 capable.
very similar sound to fiio x3 dap.

So you connect from your laptop to your TV using HDMI, and then from the TV optical to DAC and then RCA to stereo amp?

that's what i did - except no laptop. since the little fiio is usb powered i use one of the tv's usb so now power cord required.
i am now using a powerdac - optical into powerdac then straight to speakers.

Yeah that optical out is a blessing.

I'm using all 4 HDMI inputs on my TV.
A single Toslink cable to the soundbar,
and it's done. Simple.

And I thought I was being so clever...

Always viewed optical as the ginger step-child of connections for some reason.

You had to see the look on my brother in law's face when I setup his this way :giggle: He thought it was sorcery  :BWAHAHAH:

I had a TV with no RCA out (I don't know why they would do such a thing), also ran a short optical into a small cheap DAC and then into my amp.

That was my problem as well, except that my problem was escalated by the need to display images either on the TV or Projector (needing distribution of each video source to both the TV & Projector), let alone audio to the stereo system.

So my solution was to use a 4x2 HDMI Matrix (4 inputs, 2 outputs) with an Optical Audio out:
(https://ae01.alicdn.com/kf/HTB1ukVNPVXXXXa6XVXXq6xXFXXX8/New-HDMI-Matrix-4X2-4-Input-2-Output-Switch-Switcher-Splitter-With-Remote-Control-Support-4K.jpg_640x640.jpg)

So for audio from low quality audio sources like DSTV and Xbox, I use the Optical output from the HDMI matrix straight to my DAC's Toslink input, then only the high quality sources like the PC and CD transport sends digital audio directly via USB and Coax respectively to the DAC.

That way, both my audio and video problems were resolved without an AVR or Surround Processor.

It works really well actually, don't know where my negative perception of optical came from.

Most modern TV's do not have analogue out audio anymore.

I was toying with the idea of a switch box but that was yet another remote to teach the Mrs, yet another wall wart and I've had endless issues with the things over the years. For your use case there's not much choice though, I don't think any TV's would offer HDMI passthrough.

i tried a splitter from hdcables previously.
it had a significant impact on picture quality with no noticable improvement in audo.

Also using optical out from the TV to my ancient Denon 3805. Don't use it often, but it works. :)

Generally use the TV speakers but for movies will switch to the DAC and big system. Saves me from running the valves too much while watching nonsense.
