ALSA has two utilities for playback and recording:

At the first glance, the playback and recording of Audacity seem to be
identical to those of the standard utilities of OSS4 and ALSA.
This should be verified, of course.
And this is not so difficult to verify.
The problem is that my magic solution fails to produce miracles.
I still have a distorted playback on Ubuntu 9.04 with ALSA and Pulse.
This might be a problem of some notebooks.
There is a reason to believe that PulseAudio has a kind of global equalizer
for the entire sound system.
I found this link:
HOWTO: PulseAudio Fixes & System-Wide Equalizer Support
Appendix D: System-Wide Equalizer
In this section, we will configure PulseAudio to use equalized output, which
is especially useful for laptops speakers which have very poor frequency
response. If your sound is "tinny" or distorted at high ranges, then this
will most likely enhance the quality of your audio.
You see, this "global equalizer" was proposed a magic solution with which to
fix the distorted playback of your notebook!
It is incredible!

And I have an excellent playback on the box with Ubuntu 9.04 and OSS4
