Bug Description
On playback I get a rough static that crackles corresponding to the waveform intensity; on occasion the sound may start as noise and then flip into proper sound output, but when paused the subsequent playback will produce static and pausing that will crash the program. I have tried Playback set to Alsa/pulse and Alsa/default, both give this behaviour. When the selected sample is played as noise, the scrolling cursor works, but appears to be scrolling by much faster than real-time.
also, when the playback works, the scrolling cursor behaves very strangely: the thin line may not move at all, or a segment of it may stay put while another part of it scrolls along with the sound.
This is a fresh upgrade to 13.10 on a 64-bit Ubuntu machine, a ZaReason Strata laptop with nvidia sound (according to alsa).
Audacity worked fine on 13.04, occasional lock ups, but Audacity is prone to occasional lock-ups, and the sound was fine. Audio works fine with other audio apps including youtubes, totem, vlc and sushi. If I highlight a segment of sound in Audacity and export to disk as mp3, sushi will play the resulting mp3 fine. The problem seems peculiar to Audacity playback.

just re-ran this with Audacity 2.0.6-alpha-Oct 30 2013 from the ppa:audacity- team/daily and I get this same behaviour, although I now notice that I get the following output on stderr
ALSA lib pcm.c:7843: (snd_pcm_ recover) underrun occurred
when the program begins (sorry I didn't think to include cli output last time) I get the following ...
