The workaround in #14 used to work for me before 15.04 and before buying my new PC (both of which coincided). Now, this bug is here to stay, and none of the workarounds above fix it.

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.
