CAE non-existent sessions #949

Closed dklann closed 2 months ago

Running Rivendell 4.1.3int1 (commit 15f550b9) on Linux Mint 21.3. This is a virtual machine on which previous versions of Rivendell 4 worked as expected.

When attempting to play a log in RDAirPlay, the VU meters do not move, no sound is produced, and the countdown and count-up timers do not move. But Cuts transition from one to the next as if they are playing.

The system journal contains the following messages:

Mar 14 16:12:10 u2204ram rdairplay[4543]: loaded log '240314' in Main Log Mar 14 16:12:10 u2204ram ripcd[4494]: received rml: "MN 1 0!" from ::ffff:127.0.0.1 Mar 14 16:12:15 u2204ram caed[4493]: attempted to operate non-existent session, serial: 1 Mar 14 16:12:15 u2204ram caed[4493]: attempted to unload non-existent session, serial: 1 Mar 14 16:12:15 u2204ram caed[4493]: attempted to operate non-existent session, serial: 1 Mar 14 16:12:15 u2204ram caed[4493]: attempted to operate non-existent session, serial: 1 Mar 14 16:12:15 u2204ram caed[4493]: attempted to play non-existent session, serial:1 Mar 14 16:12:15 u2204ram rdairplay[4543]: log engine: started audio cart: Line: 0 Cart: 60001 Cut: 1 Pos: 0 Serial: 1 Card: 1 Port: 0

I looked briefly at cae/cae.cpp and cae/playsession.cpp, but I'm unable to discern what a "non-existent" session is.

Any pointers on what to look for in troubleshooting this?

Thanks!

Two possible spots in the source code that this could have come from: line 692 or line 743 of 'cae/cae.cpp'. Both of those sections deal with manipulating the virtual mixer built into CAE.

Combining this with #951.
