After all those years, I finally figure out which audio codec this thing needs!
This Microsoft website lists all the codecs that windows xp and later versions of windows have by default: https://support.microsoft.com/en-us/help/899113/the-default-codecs-that-are-...
One that almost immediately stands out is: DSP Group True Speech. After a bit of searching on the internet (here https://social.technet.microsoft.com/Forums/windows/en-US/a4ecc925-5e65-46fd...) I found that this page allows you to get the codec http://www.bytescribe.com/downloads/tsp_codec_install.exe
Note: I only tested it on WINE under linux. Under wine, the process is a bit less straightforward. Aside of installing the codec itself, you will also need to edit drive_c/windows/system.ini and add msacm.trspch=tssoft32.acm under [drivers32] so that the codec is known by wine. Note: I didn't test it starting from fresh wineprefix, I also had windows media player 9 installed. Running this 64k thing also requires installing directx using winetrics, and copying gm.dls from a real windows installation from C:/windows/system32/drivers.
It's so complicated maybe it's not worth bothering.
