Sound card not detected anymore with Sam460LE

Another strange issue that surfaced recently is that my Sound Blaster PCie card stopped producing sound and AHI is not listing anymore working options. I thought SB went bad and ordered another one but it shows the same issues. Is my board gone bad? Emailed ACube but I have little hope in their support.

I have managed to have my sound card functioning back again by copying Workbench folder from WorkSD partition on the amigaOS sd card to the boot partition on the hard disk. Something is missing on official installation CD and installation image on SD card because I could not make sound card work after regular installation and updates.
