Setting up startup sounds doesn't work

[rado84-github]

 * Cinnamon version: 5.2.7
 * Arch (LTS kernel, if it matters)
 * Graphics hardware *and* driver used 510.54, GTX 1660 Ti
 * 64 bit

Issue Adding a startup sound (Starting Cinnamon, in my case) doesn't work. The sound doesn't get played at startup and also pressing the play button to hear the sound doesnt' do anything either.

Steps to reproduce

1. Open "Sounds" and select any desired sound file to set it up as a startup sound. Also set sound volume for the desired startup file.
2. Press the "play" button next to it in order to hear it. Notice that no sound is being played.
3. Reboot the computer and notice the sound doesn't get played at starup.

Expected behaviour A startup sound should be played and perfectly audible. Pressing the "play" button next to that sound should play it.

Other information I noticed that the file selector window lists only wav files, so I chose a wav file. The wav file is perfectly fine because I use as a ringtone on my smartphone and just for the test (to make sure it's fine) I tested it as a startup sound for Windows 10 - it plays just fine in Windows 10, so whatever is wrong here, it's in Cinnamon.

Can you attach the sound file itself (maybe in a ZIP) to test

I've got no problem playing ogg or oga sounds, and just tested a random wav download and that's also fine. - this is on Mint with Cinnamon 5.2.7. Does your file play elsewhere nemo-preview, meda players etc?

Yes, it plays everywhere else - media players, my phone (I'm usin' it as a ringtone), even Firefox somehow managed to play it locally.

This is the wav file: Crisis on Infinite Earths.7z https://www67.zippyshare.com/v/PeOjFTt9/file.html

This is a recorded video for you to see it's not working: simplescreenrecorder-2022-05-27_17.04.37.mkv https://www67.zippyshare.com/v/62yuMpyw/file.html

OK thanks - so that file doesn't work for me either - previews OK with nemo-preview, plays ok in MPV, interestingly neither wav produce any sound in Celluloid.

It works ok if it's converted to vorbis

ffmpeg -i 'Supergirl - Crisis on Infinite Earths.wav' -codec:a libvorbis -qscale:a 10  'Supergirl - Crisis on Infinite Earths.oga'

Supergirl - Crisis on Infinite Earths.oga.zip

I don't wanna degrade it by converting it to a lesser format.

I didn't know mediainfo could work in terminal. Seeing smurphos' last post, that gave me an idea what might be wrong and now I know for sure, after converting it to 16-bit using Audacity: Cinnamon doesn't support anything higher than 16-bit PCM WAV.
