Now if you do specify 'channels 18' in the dmix slave definition, the error is as follows :
aplay: set_params:827: Sample format non available
I have 'format S32_LE' set in the dmix slave definition, but it doesn't seem to be taken into account.


It should be. Did you used 'aplay -D plug:your_dmix'?

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.
