Without being an expert these things come into my mind:
1. Why do you want to use Windows Media Player? VLC is much superior than
WMP and there are also other free players.
2. This seems to be like a missing audio codec. On Windows I use a codec
pack like K-Lite Codec Mega Pack. It has everything I need and it get's
regularly updated. Link:
https://www.codecguide.com/download_k-lite_codec_pack_mega.htm
AFAIK VLC comes with it's own codecs that's why you can play with it.
3. If it still doesn't work, you can try to re-encode the audio stream by
using e.g. mp3
