Public bug reported:
This specific problem is occurring on an HP Mini 1030NR and may be
related to bugs #244754 and #229522 in some way. Audio playback was
fine under the original Windows install and a standard install of 8.10
(though in 8.10 the volume meter was skewed such that 0% to 80% produced
almost no change and 80% to 100% was the only useful part of the volume
meter). Audio playback under 9.04 does not function at all through the
external speaker, except to produce a loud hissing sound when the
computer is restarted. When plugging headphones into the headphone
jack, audio can be heard, except it is accompanied by heavy crackling
and popping that begins approximately 1-2 seconds after plugging
headphones into the jack. Additionally, when plugging headphones in,
crackling and popping can be heard from the external speaker briefly.

The system and PulseAudio do not appear to print any error messages
regarding audio (though PulseAudio prints a message stating "warning:
'pulseaudio' uses 32-bit capabilities (legacy support in use)").
This system is not used for anything important, so I am happy to test
any potential solutions for the issue.
