No sound incomming email

[tuurke]

After adding an mp3 sound (notifications) to obtain a personal sound at a incomming email.
I find the mp3 in the emailsound list.
When I click it the sound is playing correctly.
So I indicated this one in the list.

But it isn't playing when an email is comming in.

I did the same for a sms/mms...here I receive a sound.

Question: can an email produce a sound at arrivel ?

Thanks for helping
