I have the same problem with a Vaio PCG-R505TFP. Looking at your dmesg it looks like it is basically the same motherboard chipset (ICH3-based) but with different processor (mine's a PIII-M 1200). Anyway, I did a little bit of snooping and found that pcm0's interrupt doesn't seem to be getting as far as the interrupt handler (via judicious use of printf()). The symptom I have is is that xmms doesn't work at all, and ogle works for about one samples worth of data (probably because pcm0 and the DVD-ROM on firewire share irq 9). Have you tried booting the machine with ACPI disabled? All mine does is panic in what might be the PNPBIOS code. I expect that if/when you use Windows on the the machine the sound works fine? I can also supply fairly verbose boot messages (with lotsa ACPI debug) and extracted DSDT files if necessary (although not until tomorrow). (Personally I blame interrupt routing, but I have no evidence at all to back that up). Iain
