Many motherboards with on-board sound also have an 'AMR' slot into which a card can theoretically be inserted carrying a better/different codec. Such motherboards typically have a row of jumpers that can connect the sound chip (or sound function in the southbridge) to either the on-board codec or the AMR slot. The error you quoted above is exactly what you get if the jumpers are set for the AMR slot rather than the on-board codec but the AMR slot is empty. Since you have two machines and one of them works, you can just compare the jumpers between them; you don't even have to search for the motherboard manual :-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
