So, I believe I have a good solution... 1. You will have to take ownership of the files/folders to complete these changes. 2. Replace the soundai.cfg with the soundai.cfg file from B737_800 folder. 3. Delete the sound folder in the b747 directory 4. Copy the sound folder the B737_800 directory to the b747_400 directory. 5. Open the sound folder you just copied in the d747_400 directory. 6. Delete the following files (these are the ones causing problems with the 747 sound sliders). ban11.wav thru ban24.wav and bbn11.wav thru bbn24.wav... Once complete, the sliders will work...

The previous replies are notable but don't really solve the problem, they are more of a work-around. I have spent hours trying to fix it and this I believe solves it. 1. You will have to take ownership of the files/folders to complete these changes. 2. Replace the soundai.cfg with the soundai.cfg file from B737_800 directory/folder. 3. Delete the sound folder in the b747 directory 4. Copy the sound folder the B737_800 directory to the b747_400 directory. 5. Open the sound folder you just copied in the d747_400 directory. 6.
