Using gentoo kernel 2.6.30-r8, i have added the emu10k1 device driver to the kernel, initially i compiled these in but i gave up on this, so i recompiled the kernel again using sound modules. However, my sound devices are missing, alsaconfig seems to acknowledge the card, but alsamixer does not and neither does anything in proc. I have tried running the script snddevices to create the devices manually but for some reason they do not work. I do not have alsa-driver installed and I am not using OSS, although i have included the oss api's as modules in the kernel. I have also run several straces to see what files seem to be missing. There doesn't seem to be anything i can do to force udev to rescan the hardware and add the devices. I have also tried kernel 2.6.31-r5 and this seems to have the same problems. I can't revert to a previous kernel, because this is a clean install, although I know that in previous kernel releases this has worked on this system using the exact same hardware configuration. I have alsa-utils, alsa-headers installed.

Reproducible: Always Steps to Reproduce: 1.On an ia64, emerge kernel-sources 2.6.30 r5 2.compile alsa into the kernel or leave as modules 3. Actual Results: udev (v141) is not creating the sound devices, alsa and proc are not detecting the sound card. Expected Results: the kernel needs to successfully update udev with the soundcard information so udev can create the devices so that i can play sound.
Recompiled this kernel with alsa modules compiled in and it just worked straight off. Not sure what I missed the first time, but it was definitely a problem with the kernel configuration.
I also changed the system from HP-zx1/sx1000 with software I/O TLB to: DIG-compliant Which reminded me that I had this problem before with the system type affecting sound. I will play about with it some more tomorrow.
