The AmigaOne XE-G4 was finally released in June 2003, running the 800MHz G4 processor (upgradeable to 933MHz warrantied and 1066MHz unwarrantied). While these boards were supplied with AC-97 codec onboard, it gave problems when activated and the sound quality was poor, so it was recommended that a separate sound card be installed. Later versions of the board did not even have the chip fitted. Then in October 2005, Steven Brookes discovered that it could be made to work after all, so Davy Wentzler created an AHI driver for it and the sound quality was on par with the SoundBlaster Live card.
