[FFmpeg-user] Concat AAC failure

I am having an issue with this concat command:  ffmpeg -i
"concat:Part1.ts|Part2.ts" -c copy -bsf:a 

aac_adtstoasc output.mp4

I converted 2 mp4 files to ts to concatenate.  These files work perfectly
when played separately as 

ts files.  When I concat, I get perfect video with no audio.

Here is the mp4 codec info:

Stream0
	Type: Video
	Codec:H264-MPEG-4 AVC (part10)(avc1)
	Resolution:3840x2160
	Frame Rate:29.970029
	Decoded Format:4:2:0 YUV

Stream 1
	Type:Audio
	Codec:MPEG AAC Audio (mp4a)
	Channels: Stereo
	Sample Rate: 48000 Hz

I'll attach the file shoring the error

Any idea what is going wrong?

Here is the console log:
