2.12.5 and the problem returns

This is not strictly correct.
Yes, you do require a splitter although in practice it is a duplicator!!!
In other words, one stereo signal in and two identical stereo signals out.
During the setup of Direct Optical mode, it is the speakers that are configured to use either the left or right channel.


I have been using a rather more involved Direct Optical mode solution for a number of years.
It has been extremely stable and has allowed me to change the audio sources at my convenience as and when new options are available.  If an audio source does not work I am free to try something that does.  That's more than you can say for the Devialet offerings.

Oh, interesting. Is the duplication necessary ? It seems overkill to me to feed L/R onto each ADC/Optical to just discard one of them at the end.

I've ordered the second ADC (With the hopes that it'll work as well on my second Phantom which is a bit newer), so I'll try this. If I'm happy with this solution, I think i'll try opening the Swissonics to see how they are made. Eventually I could do my own PCB to make an "all in one" solution that even could be a superior solution to Devialet's software. I've dabbled with audio in the past and made my own ADC/UPnP/AirPlay server (just all analog) that, to the contrary of the Phantoms, got a four years uptime without any kind of downtime.
