List devices

Hi,

I have a dmix plug that's connected to hw dev 1 (/etc/asound.conf):

pcm.i2s_play {
           type dmix
           ipc_key 1024
           ipc_key_add_uid 0
           slave {
                   pcm {
                           type hw
                           card 1
                   }
                   rate 96000
                   format S24_3LE
           }
    }

I cannot get it listed with ALSA API function snd_device_name_hint. Neither does aplay -L list it.

But I can play to it: 

# play -D i2s_play -f S32_LE -c 2 -r 96000 /dev/urandom
Playing raw data '/dev/urandom' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo

I'm working on an ALSA C++ backend so in order to use the device I need to be able to list it, so how to ?

Regards
/Robert
