ALSA lib pcm.c:7963:(snd_pcm_recover) underrun occurred

[Walter Ribeiro]

When recording to a new track in Audacity, occasionally this problem occurs.
I hear a lot of noise and the record stops.

The output is:

I'm using Ubuntu Studio 16.04 fresh install, regularly updated.
Audacity 2.1.2

Status changed to 'Confirmed' because the bug affects multiple users.

audacity (Audacity 2.1.2) hangs on 3-hour MP3-file with such messages (or maybe these messages is not connected to the hangups):
