I have been running the efika for about a week now and still have zero sound. A suggestion in other thread referred to Firmware updating. I ma not sure what to do here. Below is the firmware revision reported by my board.

20070122084838 V1.3

How do I tell if this is most up to date? If not up to date then which specific update file do I grab?

no that's the most recent. But is it possible that you disabled the soundchip somehow in the firmware?

Just try to reinstall the firmware: http://www.powerdeveloper.org/platforms/efika/firmware
