    Nice work. I’ll consider building that TI IC into my microphone circuit so I can get optical output without having to worry about interference from the PC. With a few low-noise pages out of Marco Reps’ book.

    May I ask a question referred to s/pdif. I've got a PC soundcard that should have spdif out but corresponding components are not populated on the PCB. There are places for it and also pcb mask says which component should be soldered. I think that schematics should be somewhat standart for such things but I'm not familiar with it. Is it possible to restore this function that has been disabled by manufacturer? This is an old soundcard with interesting wavetable synthesizer onboard and I would like to get opportunity to get clean digital output avoiding it's bad analog audio output which isn't good quality. This soundcard has even spdif out in windows driver but no way to use it.

      Hi. Sorry for veery delayed reply but as I re-started the channel I will reply anyway. Unfortunately, it is impossible to say if it has been disabled somewhere else in HW-level as well. I would check with oscilloscope if you can see any signal in there.

    Is there any chance for a 4x I2S to ADAT-Lightpipe converter, e.g. based on 2x TI SRC4194 + 1x Coolaudio V1401?

      Unfortunately, at least not right now. Everything I do for now comes from my own needs/interests and my background is in Hifi and home audio, so unfortunately don't know much about Pro Audio needs. However, I do get occasional pro audio customers and requests so I am definitely keeping the options open trying to serve that space in the future.

      @@kaamostech There is a home audio application: Convert 4x I²S (7.1 channels) HDMI audio to ADAT Lightpipe to get 7.1 into an USB audio interface (HDMI audio extractor -> 4x I²S -> ADAT Lightpipe -> USB audio interface). This would e.g. allow to run CamillaDSP on the HDMI audio to to active-crossover, channel/down mixing and/or frequency-response-correction.
