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

[Gaetan L. <sou...@ga...>]

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
