Public bug reported:

Binary package hint: pulseaudio

Hi,

just upgraded to current Karmic beta. All went fine and well, but I have
one issueabout the volume control - as it's working now it's almost
dangerous.

When I adjust the volume slider I can max out my laptop speakers at
about 15%, any higher and they are about to blow. When using a headset I
can't go over 9% before the sound gets dangerously loud. When using the
volume buttons on my laptop I can start at 0%, then click two times
until the volume becomes so loud (12%) I don't dare go any further when
wearing a headset...In Jaunty I had a much more fine-grained control.

After inspecting how the new volume control works, I see that it adjusts
both the master volume and the PCM according to some algorithm. While in
concept I understand this is smart in order to keep noise down, it works
really terrible in my case. Imagine having a computer that if someone
(or something!) sets the volume to anything above 20% and your speakers
(and hearing) stand a good chance to blow.

Laptop:
Fujitsu Siemens Si1520.
lspci -v attached.
