System.Media.SoundPlayer doesn't play specific encoding Lavf58.29.100

[murilocmg14]

I have a wav audio file that has a Lavf58.29.100 that is getting an error saying that is not a wav valid audio file, but when using FFMpeg to change the encoding to 59.33.100 and using ADPCM as well, the new wav audio start to work on this code, so i was wondering if this encoding is not supported on System.Media.PlayerSound

using (var sound = new System.Media.SoundPlayer(path)) { sound.PlaySync(); }

The first image is about the converted audio file, that has Lavf59.33.100 ADPCM Encoding and the second has the Lavf58.29.100.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

SoundPlayer uses PlaySound function. It should be able to play WAV file with pcm_s16le codec (which is just a regular uncompressed PCM WAV, used very often). I guess the file is invalid if you can't play it. Does it play in Windows Media Player?

Yes, it runs on Windows Media Player.

This is the audio that has the error and the one that does not have the error

The "invalid file" error comes from the OS, we just capture the failed interop call and throw an exception:

Can you put a breakpoint there and tell us what is the error code that you're getting from the OS?

By the way, this is the repo for the libraries documentation. Is there a documentation issue/bug that we should address?
