ADDIT: Hallelujah! Un-installing BTS, reinstalling, re-patching to 3.1, and then installing the 1.0 and 1.1 RTW upgrades has brought sound back to RTW!
In short, the problem I describe below in my original post seems to have been fixed conclusively.
I've had two types of problems with RTW scenarios that might constitute bugs.
First, before I installed 3.13 patch, I had the game lockup a couple times in the late game when it was getting to be lots of units. This prevented me from winning at least twice. When I would reload the .sav, it would lockup again. I presumed this was just a processing overload sort of issue, else an accumulated corruption issue?
Second, after I installed 3.13 patch, I had a new problem with no sounds right from the beginning. I have not upgraded to the upgrade pack for RTW. This problem only occurred with RTW mods and all three stock scenarios (both 1936, and the 1939 scenarios).
Here is the procedure I've followed. Load BTS. I hear all the
startup music. Load a Mod. Still hear sounds fine.
Select Road to War. Select Single Player. Select Load a Scenario.
(It works the same if I load the scenarios via the BTS Content screen)
Select RTW Europe 1936. Select Germany. Select Noble Difficulty.
The Signature screen of US troops walking the burning Germany village
comes up (full screen), followed by the smaller popup window of
info about the Mod (no sounds). Click OK to close the smaller window and the game progresses to the game map but no sound.
The signature screen with the air-raid warning pops up to start the game.
I hear the air-raid warning. Close this screen, and no more sounds.
Move an infantry and fortify or sentry it: no sound.
Move a bomber or fighter to another city: no sound.
Zoom the map in or out: no sound.
Click open a city: no sound.
Move a tank and fortify or sentry it: no sound.
Send a plane on a recon mission: no sound.
What I expect to be happening is everytime I tell a unit to fortify or move,
etc., I should hear sounds, plus there should be background sounds (cows,
birds, etc.) and when I go into a city, I should hear town noises. I hear
none of these. I attach a .sav.
Exit to the Main Menu for the RTW Mod. Start another SP game, this time
RTW 1936 Pacific. Follow all the same steps, except play as Japan.
Same problem with RTW 1936 Pacific.
Exit to the Main Menu for the RTW Mod. Start another SP game, this time
RTW 1939 Europe. Follow all the same steps, play as Germany.
Same problem with the RTW 1939 Europe.
This is not happening to me in other scenarios, or non-scenario SP games.
After I diagnosed this this morning as being common to all the RTW scenarios, I uninstalled BTS (and Warlords too since I'm never gonna play it again anyway). I then reinstalled BTS, but have not yet patched back to 3.13, nor have I tried to install the RTW upgrade pack 1.
My questions: (1) am I the only one experiencing anything like either of these two possible bugs (the late game crashes in the original patch, and the no sounds in the 3.13 patch); (2) is it likely that uninstalling and reinstalling has fixed it? If so, then I'd like to go ahead and repatch to 3.13 so I can (a) start a PBEM with some friends, and (b) install the RTW upgrade pack 1.
