No sound with 36 kHz Ogg Vorbis file and enabled equalizer
April 25, 2015
As soon as the equalizer is enabled, there is no sound although the file itself is played usually.
An example file is attached. I have tested 3.5, 3.6 and 3.7-devel, they all show the same behavior.

Once again I am wishing I knew more about digital filters. There is some code that disables the higher frequency IIR filters for lower-rate audio to avoid this very problem, if I understand it correctly. Perhaps it is not quite right. I mean this bit of code in equalizer.cc:
/* Calculate number of active filters */ K = AUD_EQ_NBANDS; while (CF[K - 1] > (float) rate / 2.2) K --;
