There are some OpenSource players that handle wma files on multiple platforms, though the OpenSource aspect may be uncomfortable with a commercial product. OpenSource libraries often have a "copyleft" license that allows them to be used within closed-source products.

Certainly ffmpeg/ffplay, mpv, mplayer and vlc are available on Windows, Mac, Linux, Android and probably a few other platforms.

mpv and mplayer will each run without a GUI, I think vlc will not.

ffplay is part of the ffmpeg suite and plays the file directly, it has an option -nodisp to stop the GUI.

ffmpeg (and libavcodec) has codecs for multiple formats.

All of these will handle audio and/or videa; all will handle wma.
