Any example to load this with ld10k1?

Also, could you make a patch for inclusion to alsa-tools/ld10k1 CVS
tree?  Such a thing is nice to share in the public tree.

I have inserted this between tone and vol_master:

#Tone
$LO10K1 -n --ctrl c-bass0,bass1,bass2,bass3,bass4:Tone\ Control\ -\ Bass,t-Tone\ Control\ -\ Bass:2,v-Tone\ Control\ -\ Bass:1,c-treble0,treble1,treble2,treble3,treble4:Tone\ Control\ -\ Treble,t-Tone\ Control\ -\ Treble:3,v-Tone\ Control\ -\ Treble:1,c-toneonoff:Tone\ Control\ -\ Switch,t-Tone\ Control\ -\ Switch:4 --patch_name Tone\ Controls -a tone.emu10k1
#Input
$LO10K1 --conadd "POUT(PCM Multi Volume)=PIN(Tone Controls)"
$LO10K1 --conadd "POUT(Stereo To 51)>PIN(Tone Controls)"

#Equalizer
$LO10K1 -n --patch_name EQ10 -a eq10.emu10k1
#Input
$LO10K1 --conadd "POUT(Tone Controls)>PIN(EQ10)"

#Master

Thanks.  It would be nicer to include the example scripts like above
in the patch.  Could you add them?

ld10k1 equalizer patch

[Piotr Tajduś]

[-- Attachment #1: Type: text/plain, Size: 196 bytes --]

There were problems with EQ10 on Sound Blaster (caused by ACCUM or macmv 
instruction, i am not sure), so i made some changes. Now equalizer 
should work also with SB Live.
