Lesson learned.

Done. Here are my results: Is the message "Sequencer driver snd-seq-midi 
is already loaded" O.K. to ignore?

Hmm... here's what I got: I'm a little concerned about card0, which is a 
directory. There doesn't seem to be any mention of the Midisport here. 
I'll reboot (read more below).

[root at localhost root]# cat /proc/asound/card
card0  cards
[root at localhost root]# cat /proc/asound/cards
0 [Live           ]: EMU10K1 - Sound Blaster Live!
                     Sound Blaster Live! (rev.7) at 0xdf80, irq 9
[root at localhost root]# cat /proc/asound/card0
cat: /proc/asound/card0: Is a directory

Just as a side note. Before applying all of the above changes, my system 
seems to be teetering between to states of operation. In one state of 
operation, I don't have my Midisport 8x8, but have system sound 
(beeps/notifications) from my SB512PCI. When I go to CCRMA to configure 
the sound card, I'll get system sound, but Qjackctl had a little problem 
starting the card, telling me that assertion failed. When I reboot, I'll 
have the Midisport 8x8 then, presumably because of the changes I made, 
but then I loose the sound card (second state of operation). Perhaps the 
new modules.conf file (above) with *two* cards configured in it will do 
the trick. Let me reboot, and I'll give you the details in a followup 
email to this one...

Thanks again, Fernando :-)
