positively ancient! emerge --sync && emerge gentoo-sources will get you a 2.6.12-rc5 or whatever is the freshest.. secondly, disable OSS and ALSA in the kernel config (its ok to leave the toplevel 'sound' box checked) and emerge alsa-driver (to avoid compiling all drivers add a line to /etc/make.conf eg: ALSA_CARDS="mia,intel8x0,intel8x0m,usb-audio,virmidi" if theres still issues, you could try mm-sources (which may have the realtime stuff merged) or the realtime stuff floating around..havent had a need here as the stock gentoo kernel works fine w/ 64 & 128 sample buffer...

You could try the RT-kernel. See the attched ebuild, I'm pretty sure that's the one I used. It's the Andrew Morton and Realtime patches applied to a recent Love-Sources kernel. I haven't had any trouble, and with my HDSP the latency is pretty darned good. good luck, derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 13: "Are there sections?

Back on Sunday 10 April 2005 03:25 pm, Aaron Trumm was like: 1: update kernel to at least 2.6.11 2: make sure the jack tmpdir is set to a ramdrive (tmpfs) 3: try building jack from cvs (there's been MANY improvements) As a side note, you can patch gentoo-sources with Ingo's realtime-preempt patchset. I've done it and the only failed patches was one to modify the kernel tag (pointless and not needed) and a trivial one the fails if you have gentoo's custom bootsplash framebuffer (Nothing significant. It just adds brackets into an if statement) That patch will speed up the latency quite a bit. Use it with caution though because you will trade off speed for stability. You can also muck around with the kernel's compiler flags in /usr/src/linux/arch/i386/Makefile but again, you'll be playing with fire. -Reuben
