Some hard numbers on the effect of this patch:

A sine wave is sent through the sink, and sampled real-life timing-data is
applied to timestamps and clock. The resulting sine is analyzed for
discontinuities and gaps, so the more of them, the more audible the
sound-distortions are. Also note the "gap lenght" is the total size of all the
silence in the gaps, so bigger number = more audible gaps.


20 ms alignment-threshold and 0 second discont-wait: (original behavior)

/BaseAudioSinkSimulator/test_bug_84844_cyclic_audio_deterioration_and_dropout: 
Audio has 5 discontinuities and 16 gaps. Initial silence is 211181, and total
gap length 18448 samples
OK
/BaseAudioSinkSimulator/test_henrikb_audioproblem: 
Audio has 251 discontinuities and 165 gaps. Initial silence is 35272, and total
gap length 324168 samples
OK
/BaseAudioSinkSimulator/test_bug_84640_no_audio: 
Audio has 1 discontinuities and 3 gaps. Initial silence is 42523, and total gap
length 110981 samples

20 ms alignment-threshold and 1 second discont-wait: (new default behavior)

/BaseAudioSinkSimulator/test_bug_84844_cyclic_audio_deterioration_and_dropout: 
Audio has 0 discontinuities and 10 gaps. Initial silence is 211181, and total
gap length 12270 samples
OK
/BaseAudioSinkSimulator/test_henrikb_audioproblem: 
Audio has 34 discontinuities and 55 gaps. Initial silence is 35272, and total
gap length 173651 samples
OK
/BaseAudioSinkSimulator/test_bug_84640_no_audio: 
Audio has 1 discontinuities and 1 gaps. Initial silence is 42523, and total gap
length 2220 samples


Basically an enormous improvement in every way! :)
