I recently upgraded to Ardour 2.8.14 and now I’m not getting any sound from most of my busses in previously made recordings.
To explain: I use ardour to record sessions with my band. I start a session with a master bus and additional busses for each instrument group (guitar, bass, etc.) I also have two additional “sub-busses” for the drums - overhead mics into an “cymbals” bus and tom mics into a “toms” bus both of which are routed to the master bus. Kick and snare both go directly to the drums bus along with these two sub busses and the drums bus is routed directly to the master.
This setup worked perfectly in previous versions of ardour. No problems at all. Now, after the upgrade, I can still see the wavforms, but the only bus that shows any audio activity is the drums bus and the only way I can hear any sound from this bus is if I solo it. None of the other busses or tracks show any audio activity during playback.
I can get sound on playback when I route a track directly to the master bus, but this is not a desirable solution, as much of my processing is done at the bus level.
What changed between 2.8.13 and 2.8.14 that would cause this sort of problem and how do I go about correcting my setup?
Any help at all would be greatly appreciated.
