volume control on vostro 1320

[anfi]

hi,

 

i'm almost done with the installation of iatkos v7 on a dell vostro 1320. there a 4 annoying things:

 

1. there is sound via voodoohda, but the only possibility to control volume is in the voodoohda prefpane. any idea how to fix this?

2. sleep doesn't work

3. finder crashes frequently.

4. 2-finger-scrolling or sidebar-scrolling doesn't work

 

i would be happy about every idea concerning sound. media control buttons and the volume control on screen are linked, but have no effect to the volume of the speakers.

 

thanks!
