The launchpad ticket I've been following is
Their solution was to introduce yet another option, handle_underrun=2,
which handles underruns even better than handle_underrun=1! Or
something. Really I don't know. handle_underrun=2 is now the new
default, unless it's overridden by a user- or application-specified
configuration. Which Wine does, so we no longer get this
new-and-improved default... Have I mentioned my unending love for
audio APIs?

Some testing has shown that handle_underrun=1 and handle_underrun=2
both work well with winealsa.drv. So we'll probably drop the
handle_underrun=1 override after alsa-plugins 1.0.25 becomes common.
