Ubuntu didn't think much of my bug. They sent me the following recipe to cure it, and marked the bug invalid.

1) Edit /etc/pulse/client.conf, and change "autospawn = yes" to "autospawn = no"
2) `touch $HOME/.pulse_a11y_nostart'
3) `asoundconf list'
4) choose the desired card from the previous command's output, and use `asoundconf set-default-card CARD', replacing CARD as appropriate
5) `killall pulseaudio'

https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/348353
mentions a recent kernel patch that routes all audio through pulse. I wonder if this patch is the culprit?

It mentions a patch, not a kernel patch. I'd be *very* surprised if
there was anything kernel-side specifically routing audio through
pulse. More plausibly, it could be a libasound2 patch or even just a
hack to asound.conf/.asoundrc.

There is a kernel patch to reroute character devices to user space;
afair that patch is already in. The usage example I have seen given for
that patch is to reroute /dev/dsp to pulseaudio.
