Temporal discontinuities during silence

with 04440bc5 and P7c3a-stereo_-dtx_24400_48.zip

The next figure from top to bottom:

• Core bitrate secondary channel
• element bitrate
• coder_type primary channel
• coder_type secondary channel
• ratio_index (mixing factor between the 2 channel)
• right channel float
• right channel fixed point
• spectrum

The second figure is just a temporal zoom on one of the spot and the 3rd a spectrogram showing the issue.

• Same issue can also be observed on the left channel.
• The issue is audible at multiple places.
• So far not able to link it to a particular parameter/event
