* Revise the PCM callback system after adding multichannel audio.Michael Sevakis2012-03-03
| | | | | | | | | | | | | | | | | | Additional status callback is added to pcm_play/rec_data instead of using a special function to set it. Status includes DMA error reporting to the status callback. Playback and recording callback become more alike except playback uses "const void **addr" (because the data should not be altered) and recording uses "void **addr". "const" is put in place throughout where appropriate. Most changes are fairly trivial. One that should be checked in particular because it isn't so much is telechips, if anyone cares to bother. PP5002 is not so trivial either but that tested as working.

| | | | | | limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30097 a1c6a512-1295-4272-9138-f99709370657
