> Bug description:
> 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.
