sdl_audio_callback: No Data. Can anyone tell me what causes this error? I'm trying to make some tweaks to the pitch screen based on a conversation I was involved in a few days ago in IRC. When I enabled semitone pitch adjustment and timestretching at the same time and adjusted up a half step, my h120 simulator spat out that error and skipped to the next song. Not being well versed in the workings of the timestretching or sound output code I'm not sure what's going on. It seems like a buffer underrun of some sort, but I don't know why a half-step change in pitch would do that.
The problem doesn't occur when adjusting speed, or when adjusting pitch by percentage. It only occurs when adjusting pitch by semitone from an unprocessed position (speed == pitch). It's as if starting up the timestretching with such a large change just shocks the player into not doing anything and just skipping to the next song. -David
