When calling speak_ssml_async (in Speech Services, using Python), keep getting Error decoding audio stream, error code: -50

Question

I am a beginner trying out the Azure Speech Services' Text to Speech or Synthesized Speech feature.

I followed the QuickStart and other related code samples, also used samples generated from Azure Speech Studio. In other words, I tried multiple versions that comes with the Service tutorial (see code sample at the end)

However, when I ran my code, I keep getting this error:

Speech synthesis canceled: CancellationReason.Error

Error details: Error decoding audio stream, error code: -50

Anyone else's seen this behavior/problem? Any pointers where I should start looking?

Thanks!
