I think for starters you can check if you can you reduce the volume to the point this file does not clip.
AFAICT that mp3 file was prepared in such way that decoding produces samples that go over 1.0 (in float) or max_int (in integers). So if your audio chain is using floats from decoding until volume change then you can recover non-clipped version when you reduce the volume enough. On the other hand, if your audio chain converts floats to integers at any point before volume change, the result will always be clipped.
With Volumio I cannot, a.mp3 clips on all volume levels, no matter if I use "software" or "hardware" volume control.
I also tried to play it on HEOS soundbar which is also UPnP renderer as Volumio and there it also clips on all volume levels.
I tried to play a.mp3 locally on my notebook with MusicBee player and there it doesn't clip on any volume (or it clips so it is much harder to hear it).
I also tried the same with Foobar v2000 (v1.4.4) and it also doesn't clip.
I forwarded these findings to Volumio developer so hopefully he can fix it.
P.S. I tried to play a.mp3 with Audacity and I got clipped (distorted) sound as with Volumio and HEOS.
