Audio interface with S/PDIF or AES and volume knob

[somebodyelse]

We badly need such a box. Alas, the reason it doesn't exist is because (as implied above), you need some sort of DSP or processor to change the volume. It would also need a display, and mute button. For bonus, it should have an IR receiver. Seems to me a more useful version would be USB in/AES out although AES to AES would be more general.

I could approach a company to build one. How much are we willing to pay for such a thing?

@drandyhaas built a toslink in/out delay based on a Teensy 4.0 which also has USB that could be used for audio in/out. I speculated at the time that it could be the basis for an inline EQ box since https://www.pjrc.com/teensy/td_libs_Audio.html includes DSP functions. Turning it into an inline volume control shouldn't be too hard.

Do any of the RME interfaces offer this feature? I’ve been looking for the same thing.

All of them do, along with the DSP-equipped ADI-2 series converters.

Similar to this?
It would be nice if you could test it...

I had the same issue and bought this thinking it would be prefect, and it almost was. Lots of really cool additional features. Unfortunately, the AES clock is not passed through the interface to the aes outputs. Only the digital audio which is also resampled to 96K. So I ended up returning it, such a shame as it had so much potential.

Maybe this one.
The only difference between the SE-U55SX and SE-U88SXII is the color (white or black).
You can only get them used through Japan sites.

Sorry but I don't understand what your problem is and what are the defects and limitations of the product.

Sorry but I don't understand what your problem is and what are the defects and limitations of the product. I am assuming you are connecting the AES output of the Genelec 9320 to the AES input on the KH750?

The AES protocol passes clock data along with the digital audio. This is how the sample-rate and timing of the digital audio is synchronized between the different digital devices in your audio chain.

Yes, I was connecting:
Lynx AES16 Audio Interface (AES out) ->
(AES input) Genelec 9320 (AES out) -> to (AES input) on the KH750?

I talked with Genelec support and unfortunately, the Genelec 9320 output does not provide any AES clock data and the sample-rate for the AES OUT is set to a fixed 96K.

All Genelec SAM have an internal sampling rate of 96kHz

Exactly! So the Genelec 9320 is not super useful with (non-Gelelec) AES devices unless you working only at a fixed sample-rate of 96K.
