Title:
  problem of sampling rate with "default" output

Status in alsa-driver package in Ubuntu:
  Invalid

Bug description:
  I discovered the problem by listening a linear chirp on wikipedia,
  http://en.wikipedia.org/wiki/File:Linchirp.ogg. At about 1 sec, a
  second chirp can be heard. On the bad quality recording attached, it's
  hearable from 1.5 sec. I recorded it with Audacity playing the chirp
  sound in the same time. The playing device of ALSA in Audacity is set
  on "default". When I change it for "dmix", the problem disappears. I
  observed the same in VLC, when I change the output device for ALSA
  from "predefined" (problem) to "HDA Intel: ALC269 Analog (hw:0,0)". I
  suspect a problem of sampling rate, for example between 44100 and
  48000 Hz, in alsa configuration.
