w3m and wav files

[Richard G Riley <rileyrgdev@xxxxxxxxxxxxxx>]

Could someone please tell me how to get w3m to invoke external player
for an audio link.

e.g here there are links to the German pronunciation of each letter in
the alphabet.

Despite me modifying w3m-content-type-alist it still just
opens the file as a binary when I hit enter on the link to the wav
file. What should I do?

regards
