Hi all, I've just installed Ubuntustudio. It all works great, except after a few minutes I get lots of these message from jack: "delay of 27893.000 usecs exceeds estimated spare time of 21274.000; restart ..." (where the number of usecs are varying). After lots of fiddling and googling I discovered that acpi is probably causing it, and it consequently happens only when acpi is enabled. When acpi is disabled I can push latency down to 2.67 msecs without xrunning nomatter how hard I try....so this is good ;) I've done these tweakings with Breezy, and it happens with all of them: http://ubuntustudio.com/wiki/index.php/Breezy:Vanilla_Kernel_With_Realtime_… http://ubuntustudio.com/wiki/index.php/Breezy:Rlimits-Aware_PAM http://ubuntustudio.com/wiki/index.php/Breezy:Enabling_Preemption It also happened the same way in out-of-the-box Dapper. I'm now on Breezy with the vanilla kernel with preempt patch. My laptop is a Dell Inspiron 8600: http://www.koeniglich.de/dell_8600.html I use Alsa intel8x0 driver, and had no other problems. Jack also worked fine with acpi on other distros like PCLinuxOS, even with the non-mm kernel. I have no idea what to do next, if anyone could give me a clue it'd be appreciated. -- Ringheims Auto - Fri musikk for bilstereo! http://ringheimsauto.1go.dk/
