System Information
Replicated on multiple platforms.

Blender Version
Broken: 2.79b
Worked: unknown

Short description of error
When frequently cutting and dragging elementary strips, that gives frequent opportunities to lose audio-video synchronization, often enough without noticing that has occurred until after a while of editing. Depending on how much editing takes place after losing synchronization simply spamming undo may not be a feasible means of reversal and manual re-alignment can require excessive effort that a amateur might barely find themselves capable of, so meta-ing synchronized audio-&-video strips seems best practice however seems to disable keying in all resultant cut strips thereafter.

Whether this expected function or a bug seems unknown, however has persisted for as long as I have been using blender and I'm sure implementing keyframing inside cut meta-strips (if the functionality doesn't already exist and this isn't a bug) should be much simpler than implementing automatic audio-video re-sychronization of separated strips.

Despite never having seen another bug report or stack-question about this, I'm confident this is a widely-affectent issue and one I'm sure any novice exclusively using blender for video-editing would prioritize as an issue they would most appreciate see-ing resolved.

Exact steps for others to reproduce the error
After a meta-strip has been cut, tab to enter 'the later' meta-strip (beginning after the selected frame), select audio strip, then attempt to set a keyframe.

Error:
Could not insert keyframe, as RNA path is invalid for the given ID (ID = SCScene, sequence_editor.sequences_all["{$source-file-name}".002].volume)

The problem comes from the naming of new strips inside the new meta strip - they are both (video and audio ones) named the same, this should never happen imho, and certainly will break unique RNA path any strip shall have. Will check.
