I've had an issue that sounds amazingly similar on my desktop machine. I haven't \
actually solved the problem permanently, but I'll relay what I've discovered and \
workarounds I've implemented... I'm using FC5 on this machine with KDE 3.5.6-4.fc5 \
and the following alsa components: alsamixergui-0.9.0-0.3.rc1.fc5
alsa-lib-devel-1.0.14-0.1.rc1.fc5
alsa-utils-1.0.14-0.1.rc1.fc5
alsa-driver-1.0.14-58_rc3.fc5.at
alsa-tools-1.0.10-2.fc5
alsa-kmdl-2.6.20-1.2300.fc5-1.0.14-58_rc3.fc5.at
alsa-lib-1.0.14-0.1.rc1.fc5
alsa-driver-devel-1.0.14-58_rc3.fc5.at
alsa-oss-devel-1.0.11-1.fc5
alsa-oss-1.0.11-1.fc5
The original soundcard on this machine is an integrated VIA Technologies 82C686A/B.

On initial bootup and first login, most often no sound.
I learned I could go to Settings; Sound & Multimedia; Sound System and, in the \
Hardware Tab, select the audio device from the drop-down list and click "Apply". That \
restarted the sound system and I got sound when clicking the "Test" button in the \
"General" tab. Then logout of KDE and log back in; I had sound... If the KDE startup \
sound played during login, I knew I had sound for the remainder of that session.

Subsequently, I upgraded the soundcard with a PCI C-Media CM18738-MC6. I did not \
disable the integrated VIA in the BIOS as that caused an initial problem (now, just \
don't care or need to disable the integrated card). Since installing the new card, on \
initial boot, I sometimes have to use system-config-soundcard to tell the machine to \
use the C-Media card as default (the machine sometimes wants to use the "first" card \
it finds; the VIA). Then implement the workaround described in the previous \
paragraph. Then logout of KDE and log back in; I have sound for the remainder of that \
session.

I also noticed that having a USB webcam with integrated microphone fouled things up. \
If that cam was plugged in during boot, KDE sound system would not play and I \
received an error during sound system restart. Also, plugging in that webcam after \
bootup, trying to restart the sound system resulted in the same error, Booting \
without the webcam solved the problem (well, solved to the extent I could workaround \
it...) Since the last time I unplugged the webcam and left it unplugged, for some \
unknown reason the machine boots with the correct soundcard selected and with sound \
in KDE nearly every time.

Upgrades to FC5, KDE, kernel, and alsa components (over time) have not affected the \
problem either positively or negatively in any way I can determine.

In my case, since this is a desktop machine, KDE sessions last for days/weeks at a \
time, so this has not been more than an inconvenience for me.  In your case, with a \
laptop cycling power more frequently, it may be more of a problem, but maybe the \
above info will give you some ideas or workarounds that work for you.
