Audacity without Pulseaudio Ubuntu 14.04

Pulseaudio stopped working and I would just as soon let it stay that way for all its quirks.
Is there a way to get Audacity working with just ALSA?
The audio on the mobo is Realtek 662 6 channel high def - I can't find any reference as to whether it's full duplex or not.
I use Audacity a lot for recording and editing and this is causing a problem for me.
Thanks

What does that mean precisely? Is PulseAudio running?
Please post the output from the Audacity "Help menu > Audio device info"

It does no good. Can't Audacity be set up to record stream with just ALSA?

Yes. The "hw" options use ALSA.
However, it appears that there is some underlying problem with your computer sound system. If the sound system does not work properly, then Audacity may not work properly.

You mean "Devices"? I've tried a lot of combinations w/ no success.

I think the hardware sound system is not the problem. I think Audacity is unable to use it without PulseAudio, and PulseAudio has a lot of problems of its own.

Audacity does not depend on PulseAudio, but it does depend on a properly working sound system.

If you don't need it, could you try uninstalling Pulse audio?

It's already uninstalled, and purged.
