Maybe this is a coincidence, but I just updated udev to 077-r2 from 077-r1 (I think) and now I have no sound ("No volume control elements or devices found"). I don't see a /dev/dsp or /dev/dsp1 either, which I used to have (my USB headphones). (well, okay, there was a /dev/dsp but only after I did a cat /dev/urandom > /dev/dsp. /dev/urandom worked fine btw). Nothing else major was updated or changed that I can think of... I re-ran alsaconfig... checked kernel... everything else seems right. It was working earlier today...

Is udevd running? Try rebooting to get any new devices found properly.
I have a partial solution in accordance with the thread at http://forums.gentoo.org/viewtopic-t-409612.html "udevstart" seems to have recreated /dev/dsp. I had to tweak my /etc/modules.d/alsa (or at least rebuilt it) and then modules-update...d and then /etc/init.d/alsasound restart...ed. I had to manually re-raise the volumes with gnome-volume-control. Now I get sound back, although I'm still not hearing some sound on my usb headset because of an unrelated kernel-specific bug here: http://bugzilla.kernel.org/show_bug.cgi?id=5618 Something still seems pretty screwy though with this -r2 version. See the thread for more info. Reopening, so that someone better informed can decide what's wrong... W
I just restarted. It got "device not found" type errors on startup. Once I ran udevstart manually via udevstart , I was able to restart alsasound and get it working. Does udev have to be added somehow w/rc-update? W
Restarted, and here was the error: When restoring Alsa levels... /usr/sbin/alsactl: load_state:1250: Cannot find soundcard "0" W
RDEPEND is incorrect here. >=udev-077 needs to depend on >=sys-apps/baselayout-1.11.14 as it does not work correctly w/ lower baselayout versions (udevstart not run -> udevd not started -> missing device nodes).
I can confirm this was the problem. I had to fix some other stuff when upgrading the baselayout, but changing this dependency should fix the problem for anyone else who's having it. Thx for your help, W
I'm also having problems after upgrade from udev-077 to udev-077-r[12]. In my case it breaks NIC renaming, which works again after running /sbin/udevstart manually.
