No sound with 36 kHz Ogg Vorbis file and enabled equalizer
|Status:||Closed||Start date:||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 --;
