I've actually got the same problem with a Sony Vaio notebook, the only soundmax driver (version 4) that is available is from a site in Poland, written in Polish!
What other numbers are there on the motherboard that might identify it like 'ECS 462ddxyz', for example What more information can you provide about the motherboard, the ID number shows the chipset as being SiS761GX which is the onboard video
