Interesting Lucid regression

Your description of poor quality sound for a short time after you first login
sounds very similar to the issues I had with portAudio initially. 

In my case it was because portAudio wasn't able to obtain high priority for
its processes or use realtime scheduling. Given that in the first little time
after logging in, your system is often doing a bit of work still setting
things up and the load can be higher than average, this could be affecting
sound quality if portaudio doesn't have the right scheduling privileges. 

Grepping for pulsaudio in /var/log/messages should tell you if this is the
case or not. On my system, pulseaudio reports whether it has been able to
obtain the necessary priority and scheduling privileges.
