Timidity++ " Can't open pcm device 'default' " [SOLVED]

Hi

I wanted to connect ScummVM's ALSA output with Timidity++ daemon and here's what I get:

[enjo@myhost scilab]$ scummvm
Using configuration file: /home/enjo/.scummvmrc
Looking for sky

and

I've tried creating dmix entries in /etc/asound but it didn't help anyway.
MIDIs can be played using timidity and I play multiple sounds simultaneously using aoss. It doesn't help here. My sound hardware is onboard nforce2 AC97
Using alsa-lib 1.0.14rc4-1

Re: Timidity++ " Can't open pcm device 'default' " [SOLVED]

I got it working somehow.
Here's my /etc/asound.conf

pcm.nforce-hw {
        type hw
        card 0
}
pcm.!default {
        type plug
        slave.pcm "nforce"
}
pcm.nforce {
        type dmix
        ipc_key 1234
        ipc_perm 0660
        slave {
                pcm "hw:0,0"
                period_time 0
                period_size 1024
                buffer_size 4096
                #rate 44100
                rate 48000
        }
}
ctl.nforce-hw {
        type hw
        card 0
}

ScummVM works like a charm, though I still hear no music in Crimson Fields.

[EDIT] Sometimes launching with
aoss scummvm
command is necessary
