Until this can be updated to work with TB 115 there is a work-around using the FiltaQuilla Extension.
In the FiltaQuilla Preferences select:
Filter Actions -> Run Program
Search Terms -> Folder Name.

Use a program such as Fmedia https://stsaz.github.io/fmedia/ to play the alert .wav files.

Example:
Assume all files are installed in C:\Alerts and you have alert files Alert1.wav, Alert2.wav, ...

Create Alert.cmd containing the line
fmedia.exe %1

Create a shortcut to Alert.cmd for each wav file e.g. for Alert1.wav:
Alert1.lnk
Properties
Shortcut -> Target: C:\Alerts\Alert.cmd Alert1.wav
-> Start in: C:\Alerts
-> Run: Minimized

Test this by running the Alert1 shortcut. You should hear Alert1.wav.

In Thunderbird, set message filters on folders as required e.g.
Tools -> Message Filters -> New...
Apply filter when:
Getting New Mail
Match all of the following:
Folder Name is Inbox
Perform these actions:
Run Program C:\Alerts\Alert1.lnk
