Mine is ICH3 with the same problem; this depends on a change sometime between last Friday (worked fine) and this morning (broke) PST... It looks as if someone made a change to interrupt routing sometime since the changes to the fsstat struct (I had recompiled then and the sound problem was NOT present; today I recompile and it is.) I may be blowing smoke; the problem could also be in the sound driver itself... My system is a Sony VAIO R505ES with Yamaha sound chip, I suspect it doesn't matter just which sound chip you have. As I say, my sound was normal this morning with a compile on the 14th, and is now broken. There could also be a problem with interrupt sharing (almost everything on this laptop is on IRQ 9), but enough other things work that I somehow doubt it. (first thing that normally breaks with interrupt sharing problems is my wi0 Orinoco built-in, and *that* is working fine.) Problem here is that ICHx sound appears to depend on what some would consider a redundant interrupt routing request (at least in VAIO configuration); several people in the past have "cleaned up" the apparent redundancy and it breaks Sony's sound :-( dmesg excerpt here: pcm0: <Intel ICH3 (82801CA)> port 0x18c0-0x18ff,0x1c00-0x1cff irq 9 at device 31.5 on pci0 pcm0: <Yamaha YMF753 AC97 Codec> -- Pete
