_SndPlayFile not starting sound file

[TerryRitchie]

The literal or variable STRING sound fileName$ can be WAV, AIFF, AIFC, FLAC, OGG, MP3, MID, IT, XM, S3M, MOD, RAD (v1 & v2), AHX & HVL file types.

Ogg are usually much smaller than mp3, in my experience.

I've had best results with .OGG as well. I use Audacity ( https://www.audacityteam.org/ ) to convert and export all sound files to .OGG for QB64 use.
