Acer Aspire 5050 - Sound doesn't work

[BJizzle]

I installed Ubuntu 7.01 on this Acer Aspire 5050 notebook and after install, the sound worked fine, than after installing all the updates the sound stopped working and produced these errors during the startup. I have another laptop that's an LG (imported from Korea) and it has the exact same sound card and it works fine, even after install all the updates for Ubuntu. Not sure what all I need to provide here.

These errors show up during boot time

[68.502882] hda_intel: azx_response timeout, switching to polling mode
