Note: The GX1 CPU only supports audio with the help of SMM (system management mode). Without it (and AFAIK LB does not support SMM code) you can't use audio reliably.
The CS5530 companion which has the audio function is supported by at least one driver (for FreeBSD) which drives the audio hardware completely natively. No VSM needed. There was an effort to port it to Linux IIRC but I don't recall the outcome.
