But, when jack starts it gets the 12 i/o's from the AF12 and labels them with the UUID of the device concatenated with numbers 1 thru 12 and one channel with no number. (this apparently screws up the auto patch since the sans number channel is at the bottom of the list and "1" is at the top. (though the sans number one is indeed physically channel 0) Jack also starts with all the MOBO onboard audio i/o with "PULSE" as part of their concatenated names. I've never seen either behavior in AVLINUX. I have a system that I've built on AVLINUX that implements a tri-amp output. It includes CALF plugins, zita-lrx, and the zita replacement for a2j and j2a. First glance appears that I may be able to bypass the alsa bridge with what's showing up in the patch in UBS12.04. But, I need to determine where and how the pulse connections in qjackctrl are being made. The log doesn't show a script being run by jack start. -- Regards, Mac

Maybe overkill: grub-customizer lets you choose whichever installed kernel you want to be the default. hjh -- James Harkins /// dewdrop world jamshark70(a)dewdrop-world.net http://www.dewdrop-world.net "Come said the Muse, Sing me a song no poet has yet chanted, Sing me the universal." -- Whitman blog: http://www.dewdrop-world.net/words audio clips: http://www.dewdrop-world.net/audio more audio: http://soundcloud.com/dewdrop_world/tracks

64-bit kernel 3.x deb package?

by Ken Restivo

I've wiped and reinstalled my old Core2Duo laptop a few times, and long since lost track of where I put the custom 64-bit RT kernel I built for it in 2007. It seems like modern linuxes are using 3.x kernels these days. I don't feel like going through the whole patch/build dance again anymore though. I found one from Musix, but it won't boot on my system. Is there a working/stable debian package for Squeeze or equivalent with a 3.4 kernel or something 3.x? -ken

IIRC I was one of only two who tested the new patched polkit, but I'm anyway one of the trolls ;p. I guess on most mailing lists a subject "Lennart Poettering" with an empty mail would cause reactions, you won't get if the subject would include any other name.
