BTW: PA also have 'real time' mode which basically means that it is using the kernel scheduling for audio timing.
That mode isn't called 'real time' and has nothing to do with real time. It just uses the kernel timer instead of the sound card clock so that it can be woken up in irregular intervals. This mode doesn't work so well if the sound card doesn't allow to read the current sample position precisely (many embedded DMA controllers have this problem).
