Comment:

 I tested all samples list above with no issue in 0.27
 As I first tested on a system where the hardware support all the sampling
 rate and all the sample size, it wasn't any indications that there wasn't
 a problem...

 So I modified the tests and listen them all as follow:
 no resampling / no sample size conversion: all ok
 no resampling / no sample size conversion / Upmixer active: all ok
 force resampling to 48Khz / no sample size conversion: all ok
 force resampling to 48kHz/ no sample size conversion / Upmixer active: all
 ok
 force resample to 48kHz / force sample conversion to signed 16 bits: all
 ok
 force resample to 48kHz / force sample conversion to signed 16 bits /
 Upmixer active: all ok

 There was a long standing bug introduced in mythtv 0.24 where all floats
 >= 1.0 would be converted to either -32768 (instead of 32767) in 16 bits
 conversion, or -2^31 (instead of 2^31-1); resulting in distortion whenever
 clipping occurred.

 this was resolved in 0.27/master.

 Please upgrade.. 0.24 is long outdated
