Issue: Missing Ports & powered off speakers

I think this issue is related to the 25H2 update since I had it when I upgraded, it went when I downgraded to 24h2, now it’s back when Windows insisted on an re-upgrade.

Issue: When loading Cubase 15.0.20 build 226 (and previous). My LFE (sub) port goes missing.
I work in 5.1 and compose with my sub off, until final mixes. This is common practice.
