Comment (by blazej.lewcio@…):

 Additional info: the distortion clearly happens when the if condition at
 line 1246 (in my code) in libmyth/audio/audiooutputbase.cpp is entered.

 {{{
  1243         bdFrames = (kAudioRingBufferSize - org_waud) / bpf;
  1244         printf("BufSize=%d, org_waud=%d, bpf=%d\n",
 kAudioRingBufferSize, org_waud, bpf);
  1245
  1246         if (bdFrames < nFrames)
  1247         {
  1248             puts("       xxxx");
  1249             upmixer->receiveFrames((float *)(WPOS), bdFrames);
  1250             nFrames -= bdFrames;
  1251             org_waud = 0;
  1252         }
 }}}
