I have a problem with sound card support on free streamlit hosting. On the local computer everything works and buzzes. But I can’t configure the sound card on streaming hosting. I tried installing packages using packages.txt, but it still doesn’t play sounds. Maybe you have some suggestions. Here are the messages from the terminal:

[09:42:46] 🐍 Python dependencies were installed from /mount/src/voicechatbotstreamlit/requirements.txt using uv.

Check if streamlit is installed

Streamlit is already installed

[09:42:48] 📦 Processed dependencies!

Your host is a virtual machine running in a data center, probably several thousand kilometers away from you. It isn’t going to produce any sounds you can hear.
