When we change the resolution of DP pannel or hot plug-unplug it while playing an audio clip,sometimes we observe a silent playback(no audio).
can you rephrase this please
During no audio condition, we have noticed that the power state of the pin or the connector is D3. Optimzing the way we set the power could mitigate the issue.With this changes the verb is sent to set the power
space after .
state and response is received. Thus ensuring power state is set.
am not sure I fully understood the problem here

how does read help instead of write?
