Topic: TOSLINK Out (TV) to FIREFACE UFX II ADAT2 In is functionig randomly??

Hi There,

I try simply to connect the audio digital out from my new philips OLED 807/12 TV (via TOSLINK optical connection) to my FIREFACE UFX II ADAT2 Input, and sometimes (10% of tries) it is functioning very well, but mostly at 90% sad it's do not function (a very strong digital noise by 100% Level).
I have tried any possible settings with the result: nothing or a very loud noise.
Proper functioning sims to happen only randomly sad((
Do you have any Idea, how can I do the connection to be stable so, that it function every time?

Best regards,
Michal

I guess the SPDIF output on the TV is compatible to 2 channel / stereo signals (uncompressed PCM) as well as to multichannel formats (Dolby / DTS). But the SPDIF input on the UFX only is compatible to stereo, so it’s probably the case to have the unwanted noise when the TV gives out a multichannel stream (90%) but a normal signal when it’s stereo (10%).
I had the same issue years ago with a DVD player and its SPDIF optical out. After some research I learned about this different formats, so I’m almost sure it’s the same thing with your TV.

What about synchronization, who is clock master, who is clock slave?

What is the input status in the driver settings? Status lock or sync from ADAT2 ?

All TVs that I know have a setting to limit the optical output to PCM (stereo).

Hello,

thank you so much for such quick answers!
I have set the digital output in the TV to stereo and at the moment it works big_smile ... I hope that was the reason.
However, I am still a bit suspicious, I will give you feedback if it works in the long run.

In RME Fireface UFX Settings at the moment:

Input Options - World Clock In Term: on
Input Options - Optical 2 In: AES/SPDIF
Input Options - EQ+D for Record: on
Input Options - TMS: off
Clock Mode - Word Clock: on, Single Speed
Clock Mode - Sample Rate: 48 kHz
Clock Mode - Clock Source: AES
Input Status / AES: Sync 48 kHz

Best Regards,
Michał

Only some of the listed settings are related to your setup with the TV. Most important is to have the TV as clock master and the UFX as slave over the optical connection.

Hi ... and how to set the UFX as the clock slave?

In the Fireface settings under 'clock mode' -> 'clock source' every other selection than 'internal' sets the UFX to slave. In your case you should select the optical input which is connected to the TV (ADAT1 or ADAT2).
