Audacity doesn't work with pulseaudio anymore

From the forums I found this bug. This is an issue with the latest (1.1.7) version of alsa-lib. Downgrading it to your previous version should work around the issue for now:

pacman -U /var/cache/pacman/pkg/alsa-lib-1.1.6-1-x86_64.pkg.tar.xz

I'm running 1.1.8-1 of alsalibs and had a similar issue.  Starting audacity changed my output to the internal speaker.  I got it working with alsactl restore, then pulseaudio -k, but it's wonkey.  VLC and audacity can't seem to both use the output at once.
