Kmix issues. May you help?

[ilkyest at pop.com.br]

Hello pals. I've installed Kubuntu Maverick on my PC. My surprise were that some Sound card channels aren't shown on kmix. 

The subwoofer, center, surround, and others that until ubuntu karmic where shown, aren't anymore. What may I do to it. 

The surround channel don't work too. I've tryed alsa-config, but kubuntu says "don't found"
