I've tested the two cards i have (both work) and are having the CA0106 craved onto the chip despite having two names for the same model- it's not CA0111 (the CA0106 and CA0111 were used to replace the better EMUk chip in lower end models as all of them were used in the 3 brand series). On the sticker on the back of the card it says it's SB0570 and Soundblaster Audigy is painted onto the PCB, while the lspci command shows it's SB Audigy SE. The previous insertion was on an X-Fi card.
