exmh : audio/basic for all kinds of files ?

[beitamos@inter.net.il (shaul)]

Whenever I am trying to attach a file to a message using exmh, it says that 
its default type is audio/basic.
When I used to do the same thing under bo, it used to show the correct type of 
the file.
does anybody else exprienced it ?
Is it a matter of some settings that has to be changed ?
I tried to delete all the entries that mention audio from my /etc/mailcap (by 
editing the file), but it didn't help.
I think it is worth mentioning that I don't have a sound card. 

					Thank you.
