LTC Timecode using USB audio interface

Hi folks, I’m trying to get LTC timecode working with Onyx using a Presonus Audiobox USB96. I generated the timecode audio file using LTC Generator (which I’ve seen recommended by others) and I’m sending it to my console over Dante, which is tie-lining it to analog XLR going to the interface. Both the interface and Onyx see an audio signal but the timecode display shows a flat line, even if I increase the input gain. Any suggestions? Last time I was able to get this working I had to use a Dante AVIO USB interface, but it’s broken recently so I’m looking for another way.

Software Version:
NX Console Type or PC OS Version: PC 4.32.1311.0

Hi @zklosko

Thank you for getting in touch.

To do this, you will first need to choose the Presonus Audiobox USB96 as your Audio Input Device in ONYX > Menu > I/O Settings > Settings. I recommend choosing Kernel Streaming as the Driver Type.

Then, you will need to add this audio as an LTC > Audio input…

You can then choose this input in ONYX > Menu > I/O Settings > Timecode > Audio LTC…

The incoming clock should then be shown.

I hope this helps.
