Wow, I didn't realize this, but it seems to be a problem with UPATCH, and maybe specifically with UPATCH on Windows 10.
When I run AOE1 ROR 1.0A on my Windows 10 laptop, start a Random Map with the Small Islands layout, Reveal the whole map with the Reveal Map cheat, and use the NO FOG cheat, I hear Ambient sounds like whales puffing and a Loon bird calling. But when I run AOE1 UPATCH on the same computer and take the same steps, there are NO ambient sounds: No Whale puffing or lion roaring or birds. This must be a glitch because there is in fact a SOUND folder in my AOE1 Upatch directory containing Ambient sounds such as ocean waves.
I don't recall if this same glitch shows up when playing UPATCH on my Windows 7 computer. The glitch might not be on Windows 7 for a few reasons:
1. My Windows 7 computer shows the Players' flags in the Diplomacy menu, but on Windows 10 my game has a glitch where the Players' flags don't show up there. So maybe there are other glitches when playing on Windows 10 that I don't realize.
2. I am used to playing UPATCH on my Windows 7 computer and don't remember a glitch where there are no ambient sounds.
3. UPATCH was made about 2014, probably for Windows 7.
Next, I tried turning on WINDOWS 7 "Compatibility" mode in the PROPERTIES menu for my .exe file on my Windows 10 computer. When I did this, I heard a lion and an elephant make noises, and heard a whale puff twice. But I didn't hear the bird song (a "Loon" bird) and didn't hear the ocean waves. So maybe playing UPATCH in Windows 7 Compatibility mode is a
partial fix.[This message has been edited by rakovsky (edited 09-25-2021 @ 02:31 PM).]
