I’m seeing an issue where the Stereo Out channel has stopped passing signal. The meters on the Stereo Out channel in the mixer are moving, but no sound (also no meter movement in the RME mixer software). A few pieces of info:
1.) I don’t think it’s a hardware/driver issue. I can create a new bus, assign it to the same physical outs and get sound. That new bus is identical in every way that I can see to the non-functional Stereo Out bus.
2.) I don’t think it’s a plugin issue. There are no plugins on the stereo bus, and no inserts in the signal path.
3.) I don’t think it’s a routing issue. I’m testing by assigning the exact same signal to the new bus that I created and Stereo Out.
The triggering event may have been one of two things (but I’m not sure.) I disabled an instrument track, and opened the “Import / Tracks from Project…” window (cancelled without importing anything though).
After reloading the project, the Stereo Out bus worked as expected.
