With a ThinkPad X60, to avoid distortion when the Master volume is at 100% the PCM volume must be at most 68% (-3dB), otherwise clipping occurs. Historically, I always lowered the PCM to this level. The effect is manifest using the Multimedia Systems Selector output test to produce a sine wave, that makes clipping obvious.

With the new gnome-volume-control in Karmic, that means that clipping occurs way before 100% (68%, I guess), which makes the system sound like shit.

Editing /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common, section [Element PCM], to change "volume = merge" to "volume = ignore" works around the issue.

Thanks a lot Daniel for the hint. Otherwise I would have had to remain on Jaunty.
