You're right, I only used '-D my_dmix'.
Using '-D plug:my_dmix' works properly, so I guess the problem is 
solved, thanks !

For the record here's the working .asoundrc section :

pcm.hdsp_dmix {
     type dmix
     ipc_key 1024
     slave {
         pcm {
             type hw
             card 2
         }
         rate 44100
         format S32_LE
         channels 18
     }
}

Of course people will have to tweak the card and channels number to 
match their setup.
