#6965: Audio Copying from MKV for x265 makes the Audio One sided

Summary of the bug:
If I have a File in .MKV with x264 and I want to compress it to save disk
space, by using Processor/software encoding into x265, I get proper
outfile without any error, but Audio is single sided i.e. on right side,
and buggy, with lot of static in left side
I converted many .mp4 files with same parameters and there was no problem
with that, but all the time I used to convert .mkv files, just wasted
How to reproduce:
just convert using the given command line, convert any H.264 to H.265
with command line
% ffmpeg -fflags +genpts -i "name.mkv" -c:v libx265 -preset fast -crf 20
-c:a aac -copyts "name.mkv"
ffmpeg version
built on ... Using ffmpeg 20180102

The File's info before conversion i.e. in H.264 Form
