Given that, I would guess that a necessary driver didn't get compiled
when you upgraded the kernel. To the best of my knowledge, OSS didn't
change that much from 2.4->2.6, since it's now deprecated following
the inclusion of ALSA drivers in the kernel. I'm assuming given the
message above that you picked the 2.6 OSS drivers? I would go back
through the 'make menuconfig' from kernel compilation and double check
that everything got compiled that should be. Personally, I've had
better luck with the ALSA drivers on my i810 boxen... maybe give that
a try, if you feel up to another recompile.
But... any more info you can provide re sound daemons, what software
it is you're trying to play sound from that's behaving recalcitrantly,
would be helpful.
