It can play music through "aplay 48.wav" and modify the eq through "alsamixer -D equal"
when use the configuration as bellow:
pcm.!default {
type plug
slave.pcm "equalizer"
}

pcm.equalizer {
type equal
slave.pcm "plughw:0,0"

}



ctl.equal {
type equal;
}



i get the error information when add dmix。
# aplay 48.wav &
# Playing WAVE '48.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
ALSA lib pcm_params.c:2150:(snd1_pcm_hw_refine_slave) Slave PCM not usable
aplay: set_params:957: Broken configuration for this PCM: no configurations available


the /etc/asound.conf :

pcm.!default {
type plug
slave.pcm "equalizer"
}

pcm.equalizer {
type equal
slave.pcm "dmixer"

}

pcm.dmixer {
type dmix
ipc_key 1026
slave {
pcm "hw:0,0"
}
}


ctl.equal {
type equal;
}
