Well disabling ACPI is an option but im waiting until 5.1, as it stands = with 5.0 I go into kernel panic on disable. Unfortunetly my skill level is = not up to par with yours so I'm afraid it would be hard to pass on information. = I have tried ogle though on my machine, I am getting the same problem. BUT I have done alittle testing. As you know I have to move my mouse constantly in order to hear sound. I found another the thing I can do = that does it. If I ping flood(ping -i 0 -s 4 xxx.xxx.xxx.xxx) another = machine my sound works, but only on another machine, not if I do it to myself or loopback. The question now is what do moving my mouse and ping flooding have in = common -----Original Message----- From: Iain Templeton [mailto:iain.templeton@cisra.canon.com.au]=20 Sent: Sunday, May 18, 2003 5:12 PM To: Remington L.

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
