I’m not sure why but when I open a Steinberg Product in Stand Alone - Halion 6, Groove Agent 5, Cubase and now Spectral Layers - the clock source on my Universal Audio Apollo interface changes to SPDIF. It only happens with Steinberg products. It only happens when I open the above mentioned in Stand Alone. It has been happening in every version of every piece of software mentioned above for the last 4 years.
Yes all my software is up to date, yes I’ve uninstalled and re-installed. This is happening on a fresh install of all software/hardware on a brand new Intel Mac Mini 2018.
Universal Audio’s trouble shooting ideas have been fruitless. I have posted this here, and there are similar posts about this topic in the past. I am willing to pay a nominal fee to anyone who can figure this and fix it for me for good. It’s a minor annoyance, and it’s not work limiting, but it’s annoying as hell.
