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?

"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." ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
