hi
my .asoundrc I have:
------------8<----------------------------
pcm.filter {
@args [ ENNOISE ENBIQUAD FLAT ]
@args.ENNOISE {
type integer
default 0
}
@args.ENBIQUAD {
type integer
default 0
}
@args.FLAT {
type integer
default 0
}
type test
slave {
pcm "play0"
}
noise $ENNOISE
biquad $ENBIQUAD
flat $FLAT
}
pcm.filter_mono {
@args [ _ENNOISE _ENBIQUAD _FLAT ]
@args._ENNOISE {
type integer
default 0
}
@args._ENBIQUAD {
type integer
default 0
}
@args._FLAT {
type integer
default 0
}
type plug
slave {
pcm "filter:$_ENNOISE,$_ENBIQUAD,$_FLAT"
channels 1
rate 44100
}
}
------------8<----------------------------
If I use filter device there is no problems, for example:
# mplayer -vo null -ao alsa:device=filter=1,0,0 sweep_100-5000.wav
it plays correctly wav file
but I have to use filter_mono device, and I get an error:
# mplayer -vo null -ao alsa:device=filter_mono=1,0,0 sweep_100-5000.wav
MPlayer UNKNOWN-4.3.3 (C) 2000-2010 MPlayer Team
Playing sweep_100-5000.wav.
Audio only file format detected.

how can I pass arguments from filter_mono to filter device?
thanks
