Are you sure that sound issues are fixed already for the Apple MacPro? I'm just running 2.6.20-12-generic, but without proper sound output. Seems the needed patched aren't applied, yet.
This maybe of interest: http://lkml.org/lkml/2007/3/14/43 Especially the Line: [ALSA] hda-codec (realtek): add support for MacPro series workstations Would be great if this could get into the feisty kernel before release. This should be the last issue in getting the MacPro to be fully supported. -- Sound not working well on Apple Mac Pro https://launchpad.net/bugs/89980 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
