Re: [racket-users] Fix linux (play-sound) sound output as aplay does not work, swap for something else
Woops so I left:
(put-preferences '(GRacket:playcmd) '("mpv --no-audio-display ~a"))
which changes it to use mpv instead. This fixes the issue but nonetheless
we should fix this out of the box and have it not look for aplay first

[racket-users] Fix linux (play-sound) sound output as aplay does not work, swap for something else
https://github.com/racket/gui/issues/239
So this does not work on both Arch Linux with prebuilt racket binaries and
Debian with built from source binaries(according to a user JSGRANT on the
racket discord server
https://discord.com/channels/571040468092321801/618895179343986688/879797867903057921):
```
#lang racket
(require 2htdp/image
(only-in racket/gui/base play-sound))
(put-preferences '(GRacket:playcmd) '("mpv --no-audio-display ~a"))
; https://upload.wikimedia.org/wikipedia/commons/5/5d/Nl-honk.ogg
(play-sound "./Nl-honk.ogg" #t)
```
because of this:
https://github.com/racket/gui/blob/8aca4a224e887175975315895a42dd05b2d9ce77/gui-lib/mred/private/misc.rkt#L79
It uses `aplay` first to try and play the sound but according to this:
https://unix.stackexchange.com/questions/363176/ogg-audio-file-and-aplay-white-noise
> You cannot decode ogg files with aplay. According to the man page, the
only formats aplay understands are voc, wav, raw and au. My guess is that
aplay interprets the ogg file as raw data, hence the white noise.
so I suggest swapping the order to `sndfile-play` or whichever command line
audioplayer is available on most linux installations.
A side issue is that we should probably provide an easier way to import
`play-sound` because I want to use it with 2htdp/image with students.
