Audio Issues when transistion from comercials

Kodi 16.1 on Raspberry Pi II, ServerWMC back end.

When a network TV show transitions from the show to the commercial, there is usually a skip – audio break, sometimes a loud spike, and then the audio stream continues normally.

Not to confuse the issue but I also have another problem with CBS network TV channel continually going out of audio sync while other network and cable stations stay in sync.

Are there settings that I can tweak to help with these two issue?

Thanks,
