Hi Laura. I may be going down the wrong road here, but it appears you have 2 
cards. The one on the MOBO, and the Creative one. 

Do you have them both set up to speakers? If so. Are you sure that when you 
are getting sound output, thats it's through the Creative card, and not the 
onboard one. Please run. cat /proc/asound/cards to see what order your cards 
are being loaded, and post it . 

Do you have Qjackctl installed (the front end to Jack) ? If not, I'd suggest 
installing it, as you can play with a lot of settings. If so. Have a look in 
"Settings" and the box marked Interface. Compare the HW # with the card 
number for the Creative card from cat /proc/asound/cards. If it is different, 
change the HW # to the number of the Creative card, and try the midi again.

I'm clutching at straws here, but did have problems with my USB midi keyboard 
being detected as a soundcard, and as the USB starts up early in the boot 
process, Alsa was asigning it as the first card. I only work with the one 
sound card, an Audigy2 soundblaster, so have no idea on how the 2 card setup 
works, but it may be worth looking in Qjackctl, even if it's just to cross 
something else off the list.

All the best. Nigel.
