Hey, you have an Aspire as well? I have an Aspire 3000, but I run windows on it.

Hrm. Have you checked to see if there are any special drivers required? All of mine were installed from the factory, so, you might need Motherboard drivers for your sound, because from the looks of it, the 5601 uses an integrated card.

So ya, check to make sure that there aren't any required MB drivers.
