AAC Audio (aac_latm) not decoded from .mkv
Audio is not played from .mkv sample, in Statistics -> Audio Decoded,Played,Lost there are all zeroes blocks,buffers. VLC reports audio codec as "MPEG AAC Audio (mp4a)".
The sample is played ok in ffplay which reports format Audio: aac_latm (LC) ([2][22][0][0] / 0x1602), 48000 Hz, stereo, fltp (default)
The sample was created from .mts file using command "ffmpeg -i c:\temp\test.mts -c copy C:\temp\test.mkv".
The original .mts file has the same audio format "MPEG AAC Audio (mp4a)" and has no problem in VLC.
