If I create a new project in cubase 15, import an audio track and then insert the UAD Ocean way studio plugin, the audio does not sound. If later I save the session and reopen it then I do have sound. This only happens to me with Cubase 15, in Cubase 14 it doesn’t happen, and it only happens to me with this plugin.
A friend also has Mac mini M4, Cubase 15 and the same plugin and exactly the same thing happens to him. It doesn’t happen to him in Cubase 14.
Can also confirm this as well. Same problem on Cubase 15 with UADx Ocean Way Studios Deluxe on a MacStudio and MacPro 2019 (Intel).
I have to quit and reopen the session for it to sound 
I checked my UA Connect and saw there was a plugin update to v1.0.1, but the problem still persists. Very weird
I wrote to Universal audio and they told me that maybe cleanmymac caused it.
For me the solution was to format and reinstall everything from scratch, this time in Tahoe and without cleanmymac.
Thanks for sharing, and glad it worked. I’m not using that application, so maybe something else is triggering it.
On Sequoia 15.6
Did you reinstall everything on the Mac, or just the plugin/Cubase?
is this if Ocean way is the first loaded plugin only? I use this plugin a lot, never had problems with it. I have Mac m4 and clean my mac
I reinstalled the whole mac. Clean installation, a friend solved it by deleting a file within application support, Universal Audio/ Ua Connect, preferences, but it didn’t work for me.
I related the failure with another Realphones plugin but I’m not sure
In my case, when the failure occurred, any other ocean’s who added also gave the failure.
