Game: Riven DVD, Windows, English, 10th Anniversary/v1.2

Error: Could not find sound 2 in card 31!

Similar to #9928.

1. Load save game (prison island).
2. start dome spinning.
3. go to elevator and slide lever of sound puzzle left to right or play some tunes first before sliding the lever.

This crash does happen (same error) if you have saved catherine (or not), but if you have saved her you must first stop the dome from spinning and then start it again.

Prison Island, catherine not saved.

Thanks for your report.

This one is a script bug (it does not crash in the original, but ScummVM has extra error checks)
This is part of the script that makes the dome spin up:

playMovieBlocking(3); // Dome closing
playMovie(4);         // Dome spinning up
activatePLST(2);      // Dome closed
playMovieBlocking(4); // Dome spinning up
storeMovieOpcode(1, 0, 0, 40, 2); // Schedule ambient sound change to "dome spinning" after movie 1 finishes blocking playback
playMovie(1);         // Dome spinning

this script needs to be patched to

playMovieBlocking(3); // Dome closing
playMovie(4);         // Dome spinning up
activatePLST(2);      // Dome closed
playMovieBlocking(4); // Dome spinning up
activateSLST(2);      // Ambient sound change to "dome spinning"
playMovie(1);         // Dome spinning

Patching this will also fix the incorrect ambient sound after making the dome spin.

ScummVM now applies the aforementioned patch since commit 69dc56a.
