I haven't tried this yet. Whats involved with installing the alsa 
drivers under a 2.6 kernel?

With polypaudio I have tried forcing the rate to both 48000 and 44100
(which is the only rate my iBook/Tumbler hardware actually accepts).
In both cases, polypaudio chews up 100% if CPU time and gets killed
within about 10 seconds.

Is this something that 1.0.9rc3 is likely to fix?

" ... new TV ad for Microsoft's Internet Explorer e-mail program which
uses the musical theme of the "Confutatis Maledictis" from Mozart's
Requiem. "Where do you want to go today?" is the cheery line on the
screen, while the chorus sings "Confutatis maledictis, flammis acribus
addictis,". This translates to "The damned and accursed are convicted
to the flames of hell."
