I tried it , to no avail.  Stil no sound in Quicktime Player (macOS 10.13.2). 

It seems to me that macOS does not recognize the audio stream.

VLC reports 2 streams;
stream 0: type = video, codec = MPEG-H Part 2 / HEVC (H.265) (hevc)
stream 1: type = audio, codec = MPEG Audio layer 1/2 (mp4a) 

ffprobe also reports 2 streams:

   Stream #0:0(eng): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, progressive), 720x576 [SAR 64:45 DAR 16:9], 215 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)
   Stream #0:1(eng): Audio: mp3 (mp4a / 0x6134706D), 48000 Hz, stereo, s16p, 192 kb/s (default)

But Quicktime Player seems to see only 1 stream: the info I get is 
Source: ....
Format: HEVC, 720x576
FPS: 25
Data Size: ..
Data Rate: ..
Current Size:

Nothing else.

Best regards, Gabriel
