Justin, it solves problem with “frozen icon” on startup, but anything else … Unfortunately didn’t.
Nuendo and WaveLab have (obviously) the same problem when you press PLAY first time when app is opened.
WaveLab shows “rainbow” for a few seconds, then you must press play once again, another rainbow for few seconds and then starts to play.
Nuendo - when you press play, timeline starts to move but there is no sound for about 4 - 5 seconds. After that, sound card is start to working and it works fine when playing except recording causes disk overload randomly.
I just tried with internal soundcard (not RME) and it works with the same “audio lag”. So, I think it is Steinberg’s issue (under Mojave)…
