Public bug reported:
Binary package hint: pulseaudio
PulseAudio works, and I can get audio, but the audio appears to be
limited to 2bit sound. You can hear clicking when Pidgin or mplayer try
to produce sound for example.
Upon running pulseaudio, the following appears in /var/log/syslog. The
text below shows pulseaudio having problems twice in a row.
