When you specify a volume perhaps the following way:

    amixer set Master 100 unmute
    amixer set PCM 100 unmute

Then selecting the "Load volumes on login" will ensure that no matter how 
you adjust the volume during your session, the next time you load up kde 
the volumes will be restored to whatever they were right before you 
selected that option.

You have to make sure that your user account(s) are in the 'audio'

Here is how I got sound working on my gentoo machine:

1. build a 2.6+ kernel with alsa as modules - don't include any of the OSS 
stuff - its deprecated.

2. emerge alsa, alsa-utils, and arts.

3. edit '/etc/modules/alsa' appropriately.

4. make sure all users you want access to sound are in the 'audio' group.

5. execute the following commands: 'amixer set Master 100 unmute' 
and 'amixer set PCM 100 unmute' (note: 100 for PCM will probably make it 
ridiculously loud)

6. at this point, in a terminal, you should be able to hear something when 
you execute the following 
command: 'aplay /usr/kde/3.2/share/sounds/pop.wav'

6. you probably also want to do a 'rc-update add alsasound boot'

7. in kde, under 'sound & multimedia -> sound system' set the 'audio 
device' to 'autodetect'

I'm writing this (quickly) at work... so I may have missed something.  I 
am assuming (and recommending) that you read the following (if not 
already) as I pretty much just paraphrased it:
