Attached is a pdf with all the results of the buffer size testing on the Beagle C4 and Panda. I think this pretty much conclusively shows that increasing the buffer size when using timer based scheduling results in no improvement in cpu wakes per second. I also went back and tested alsa 1.0.24 in the audio stack to enable the recently added check for period disable. I appears that the beagle and panda do not have support, or it is not yet enabled in the driver. Does anyone know if these boards have the ability to turn off period wakes for the sound companion chips?<br>
