Partition and Sound problem in Kubuntu 6.06

[Sundar]

Hi,

I have installed KUbuntu 6.06 on my Lenovo 3000 N100 Laptop. 

1.  I am unable to play sound.  From KUbuntu wiki site 
(https://wiki.kubuntu.org/LaptopTestingTeam/Lenovo3000N100?highlight=%28lenovo%29%7C%28n100%29) 
found that there is a work around to enable sound.  I had added the line 
mentioned in my /etc/modprobe.d/options file.  But still I am unable to 
get any sound. 

Has anyone been able to configure sound on Lenovo N100.  Is there any 
more steps that need to be done after adding the lines? Am I missing 
anything?? Any pointers would be very helpful

2.  When I partitioned my disk during installation, I tried creating 
multiple partitions.  While doing so ended up with around 1GB of disk 
space which is shown as free but I am unable format it fat/ext3/Linux 
swap.  I did not understand why that space is shown as free but not 
available for use.  Is there a way to recover the lost disk space?

Regards,
Sundar
