Bug Description
Binary package hint: pulseaudio
*Everything* that is played through PulseAudio gains a high-pitched ringing tone. It sounds more or less like bad AM radio, but with bass added. I haven't a clue how to fix it so that it works properly. PulseAudio has not worked out of the box on my system for any Ubuntu release in which it has been present, and for the Karmic+1 cycle, it needs to be either *actually* fixed, or removed entirely: this is frankly getting quite ridiculous. PA is the source for a lot of bugs that can't be properly described, cannot be adequately troubleshooted, and it is apparently so difficult to fix that it hasn't properly worked since it was created. I cannot pretend to understand how to fix PA myself, and I'm a relatively technical user with a relatively basic setup, who just wants to listen to some bloody music without having to try to figure out how the audio subsystem is broken in *this* release.

To make sure this is a pulseaudio problem, can you successfully run "pasuspender -- speaker-test -D plughw:0 -t sine -c 2" in a terminal? If it does not work (i e two alternating tones, alternating left - right), it is more likely to be an ALSA problem.
