[Alsa-user] Problem to configure type multi volume control

[Gaetan Lord]

Hi I have special needs with 2 different sound cards 00:1f.5 Multimedia audio controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) 02:0a.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07) I include my .asoudrc at the end. I want to do the following, but I'm still fighting to get better control handling on the volume. I want to be able to play sound on each of them separately, and also sometime using both cards simultaneously, with aplay and xmms. Single card work fine, when I use the "mplug" pcm, it does work but !!! I have to control the volume for each source separately, with alsamixer/amixer, and I have no way to do that with xmms, I could only control a single card. I try the softvol, but it doesn't work. My question are. Any way to configure a ctl, where I could with a single command control both cards via amixer, and that I  could use inside xmms. Thank You pcm.ich5 {   type hw   card 0 } ctl.ich5 {   type hw   card 0 } pcm.emu10k1 {   type hw   card 1 } ctl.emu10k1 {   type hw   card 1 } #from http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php?module=Generic # create a virtual four-channel device with two sound devices: # This is in fact two interleaved stereo streams pcm.multi {        type multi        slaves.a.pcm "hw:0,0";        slaves.a.channels 2;        slaves.b.pcm "hw:1,0";        slaves.b.channels 2;        bindings.0.slave a;        bindings.0.channel 0;        bindings.1.slave a;        bindings.1.channel 1;        bindings.2.slave b;        bindings.2.channel 0;        bindings.3.slave b;        bindings.3.channel 1; } # ## get this one from http://article.gmane.org/gmane.linux.alsa.devel/5105/match=pcm+multi pcm.mplug{        type plug        slave.pcm "multi" }
