Use DMA for audio playback on PP502x (FS#9910 + some further mods). I can't say at this point about any change in battery life but it frees up a percent or two of CPU cycles as measured in the buffering screen. No change in recording transfers yet. Testing seemed to check out so put it out for general use and see what happens.
