|Summary||0008221: Latency compensation suddenly is way off|
|Description||I've experienced this before and asked Robin about this in a forum post. Today it happened in a repeated fashion.|
With this specific session, I would notice that the vocals would suddenly be behind in there timing. I could not figure out why. When it happened again, I routed them straight to the Master bus, instead of their originaly assigned vocal buss. After pathing in this way, the vocals were in perfect timing. Then when I patched them back into their buss, all was well.
After closing out the session and restarting Ardour, I opened back the session and all was well. BUT, this time I was working on adding an LSP Parametric EQ to the Monitoring section's "Processing" block. (I wanted to experiment with headphone eq calibration). After making some FIR adjustments, this same vocal timing error happened again. So, I closed the session and restarted Ardour again. I performed the exact same eq adjustments in the monitor processing block and it happened again. the vocals were late. Attached is the gdb file is that helps.

Ardour 6.0.45 gdb output_latency error (49,146 bytes)
FYI, when opening the session today, right from the start I had the latency issue. But, this time i did an experiment. I turn OFF (Disabled) PDC. Waited a sec, then turned it ON (Enable) again. This fixed the issue.
I still don't know why this is happening.
