I am running WebAssembly version from the demo website (https://ggml.ai/whisper.cpp/) and it doesn't work for me at all. Steps to reproduce:
1. Windows 10 19045.5737, Chrome version: 135.0.7049.43
2. Go to https://ggml.ai/whisper.cpp/
3. Download any model, for example base-q5_1
4. Choose any wav file or get input from microphone
