Package: pulseaudio
Version: 1.0-4
Severity: grave
Tags: d-i
Justification: renders package unusable

Dear Maintainer,
After I install Debian testing with a KDE environment, my volume is too loud.
When I try to turn it down, the screen tells me that the level is going down,
but the sound doesn't change until the level is almost to mute. Then, the sound
gets too quiet, so the sound is either too loud, too quiet or muted with a lot
of space in between where the volume doesn't change.

When I right-click the volume (KMix) to investigate and select another master
channel, there is only one channel listed: Internal Audio Analog Stereo. Changing
the Current Mixer option doesn't give me more channels. When I run alsamixer in
a terminal, there's only one channel: Master. If I remove pulseaudio and log out
or restart kdm or the computer (can't remember which), KMix then has several
channels to choose from, and alsamixer has about a dozen channels as well. Then,
I can pick one—like PCM—which has the full range of volume.

My computer is several years old, and its sound jack on the back is actually a
headphone jack. The Master and Headphone channels also affect the volume after
removing pulseaudio.
