it seems the bug jakemsr@ fell into several months ago has been fixed;
note that this does not add any dependency since akode needs jack which
needs libsamplerate
- lowercase COMMENT while here
discussed with and no objection from jakemsr@
- disable the libsamplerate resampler, it clips and is horribly
inefficient
- fix WANTLIB
- stop ffmpeg decoder from spamming stdout
- enable jack output
