+# TTS Troubleshooting
+
+Common issues and solutions for Text-to-Speech functionality in Talemate.
+
+## FFmpeg Not Found
+
+Several TTS providers (including [Chatterbox](chatterbox.md) and potentially others) require FFmpeg for audio processing.
+
+### Symptoms
+
+You may encounter errors like:
+
+```
+Could not load libtorchcodec. Likely causes:
+ 1. FFmpeg is not properly installed in your environment. We support
+ versions 4, 5, 6, 7, and 8.
+ 2. The PyTorch version is not compatible with this version of TorchCodec.
+```
+
+Or:
+
+```
+FFmpeg version 8: Could not load this library
+```
+
+Or generic FFmpeg-related import/loading errors.
+
+### Solution
+
+#### Windows
+
+Run the included `install-ffmpeg.bat` script from the Talemate root directory:
+
+```batch
+install-ffmpeg.bat
+```
+
+This will automatically download and install FFmpeg 8.0.1 into your virtual environment.
+
+#### Linux/macOS
+
+Install FFmpeg using your system's package manager. FFmpeg versions 4, 5, 6, 7, or 8 are supported.
+
+### Verification
+
+After installing FFmpeg, verify it's accessible by running:
+
+```bash
+ffmpeg -version
+```
+
+You should see output showing the FFmpeg version (4.x, 5.x, 6.x, 7.x, or 8.x are all supported).
+
+**Important:** Restart Talemate after installing FFmpeg for the changes to take effect.
