In joyride, TamTam doesn't work very well. Even when you start TamTamMini and just start a drum beat without playing any instruments, you get quite regular crackles/blips. At the same time as these imperfections, console messages (from alsa-lib?) appear, stating that underruns have occurred.
Downgrading to stable kernel 2.6.22 works around the problem. Sound output is smooth and no underrun messages appear.
