After suspending to ram (using hibernate-ram) and resuming, sound no longer

Check the various hybernation/acpi config files. There should be the option

resume.
My wisdom agrees with this. 90% of problems I've had getting
hibernate-ram to function correctly is all in the
/etc/hibernate/common.conf file. Please check these options very
well. For different kernel builds or X configurations, the best
settings can easily change.
If you recently updated the kernel, then please reboot once again, as
the alsa configurations can change slightly, and it will try to
auto-convert old alsa settings. Also please run alsaconf as well to
make sure the settings are correct.
Thanks, as I said, the problem I have now is that programs that play
sound (mplayer, Firefox sometimes) don't survive suspend-resume.
Actually, they survive, it's just that FF tends to lock up when watching
youtube-style videos. Sound is broken during suspend-resume, and can
only be fixed by closing all programs using the sound drivers, then
unloading and reloading the sound driver module. Unfortunately, the
panel volume changer applet (for LXDE, I'm using hardware from 2000,
remember...) is one of those programs (it took me a solid 3 hours to
figure that one out), so I no longer run that applet.
I am happy with my current suspend-resume setup, and can say that gentoo
is the only distro that successfully suspend/hibernates when using the
proprietary nvidia drivers, and the only one that runs with little
enough latency for me* (preemptable kernel ftw!). Thanks guys.
