The next obvious (but non-trivial) step is to write an ALSA driver for the K4 that can send sound out the accessory port, adding sound output capability to the K4.
For now (after
mmatej provided the "proc" port to poke), I want to add K4 sound support using this method to my "geekmaster video player" in addition to the ALSA sound support used in my "noisy rhythms" demo program (thanks to
twobob for giving me the push in the right direction).
Of course, my source code will give sound credit to
twobob and
mmatej.
