Force Audacity to Use PulseAudio, not Jack.

[lmat]

I am unable to hear any sound in Audacity. I see the bars moving as though sound might come out, but I can hear nothing.
When I run Audacity, I get the following:

[email protected]~$ audacity audio.mp3

I'm using audacity 2.1.0 on archlinux. I have an onboard audio card on a ga990fxa-ud3 (motherboard). Other sounds work on the machine, pulse audio is installed. In Archlinux, audacity depends on lilv which depends on jack, so jack is installed, but not running. Attached is an image of Audacity running. Where it says "ALSA", there are no other options, and I've tried the four options where it says "HDA ATI SB: ALC889".

I would like audacity to use pulse audio for audio. Please let me know if you have any suggestions.

It looks like PulseAudio is not running.
