Ubuntu Multimedia :: ALSA Not Detecting Soundcard On Reboot?

I'm having a rather peculiar problem with sound in Ubuntu 10.04. Specifically, every time I reboot I run through a cycle of sorts:

A). Sound is working fine. Reboot

B). No sound. "aplay -l" returns "no card found". Additionally, the hibernate and suspend buttons are missing from the shutdown menu and restart acts as log out, immediately returning me to the log in screen (sudo reboot in console works). I try to fix the problem by the following commands:

Code:

$sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
$sudo apt-get install linux-sound-base alsa-base alsa-utils
$sudo reboot

C). After rebooting sound works normally again and I get the following:

Code:

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: VT1828S Analog [VT1828S Analog]
Subdevices: 2/2

[code]...

I have "linux-backports-modules-alsa-lucid-generic" installed. I have been experiencing problems with audio since I bought this M/B, but with 9.10 things were stable and with my previous 10.04 installation bearable. Now, however, I practically can't work. I have to run the aforementioned routine every time I reboot. Additionally, I don't if it is relevant, but the problems started after I installed the audio drivers in Windows (another royal mess, but at least now it's stable and it works)
