Comment 15 for bug 292676

For me;
A fix on the non-performing machine mentioned on he previous post.
 Take the .wav file that I had chosen (which did not play) and
Using "OggConvert" convert it into an .ogg file.
OggConvert is a GUI application from the repository that 's pretty well intuitive.(you might have to install it)
 Go to thunderbird /edit/preferences/general and choose the newly created .ogg file from where you saved it.
Worked for me. Although I don't know which player did the job.
Now chosen .OGG sound file plays.
Just tried it on a whim and success,,,,,,,,,,,, if it lasts.
