Aaron thanks, I'll try that. You happen to know whether this is a motherboard issue or is kernel's acpi just not there yet? What a shame, it's such a good thing to save power :) -- Wolfgang
Hi, I'm just echoing Lee's inputs as someone who's been down the low latency path for a while now. I am currently using 2.6.16-gentoo-r2 with no low latency patches. It works fine on my AMD64 hardware, at least for low work load low latency needs. I run at 64/2 on my HDSP 9652 and get no xruns doing mostly mixing and a very little recording. However I do require realtime-lsm be enabled and loaded. Without realtime-lsm all kernels on my machine, with or without Ingo's patches, cause xruns. I have not tried the pam enabled realtime methods as there doesn't seem to be any value spending the time to do it just yet. Cheers, Mark
