#8711 F5-TTS(Built-in): No audio file was generated during the listening test.self=[F5TTSBuilt]: uuid=None, proxy_str=None, tt

The "No audio file was generated during the listening test." error means the F5-TTS subprocess ran but produced no wav at tmp/45520/listen_voice/...wav. The traceback is truncated and does not show the underlying cause, but for F5-TTS (Built-in) there are only a few possible reasons, and your log already reveals two concrete red flags:

Red flag 1 — Version/installation mismatch
version:v4.17 but root_dir:...win-pyvideotrans-v4.08-0802. The sp.exe/videotrans files were overwritten by a patch on top of an old v4.08 package, and _internal was almost certainly not fully overwritten. A missing or stale dependency under _internal makes built-in TTS subprocesses exit silently without writing the audio file.

1. Delete the folder, download the full latest package (not the patch) and extract it fresh to a short English path such as D:/pyvideotrans.
2. If you must patch, copy every file and folder from the patch (sp.exe, _internal, videotrans), then delete all __pycache__ folders inside _internal before overwriting.

Red flag 2 — Reference audio (role: voz_mex_MarioCastaneda.wav)
The listen test is using a clone-style reference wav. If that file does not meet F5-TTS requirements, the model returns nothing.

1. Confirm the file exists in software directory/f5-tts/.
2. It must be mono WAV, 3–10 seconds, clear speech, no background noise.
3. It must be registered in Menu → TTS Settings → Set Reference Audio in the exact format voz_mex_MarioCastaneda.wav#the text actually spoken in this wav. A wrong/missing text mapping causes the generation to fail silently.
4. Re-test after temporarily selecting a non-clone voice in the Voices dropdown, to isolate whether the reference audio is the culprit.

Other checks, in order

1. Model完整性: models/models--jpgalejoar--F5-Spanish is a 5.4GB model. Open the folder and verify all files are present (model.safetensors, config, vocab, etc.) and that no file is 0 bytes or named xxx(2).safetensors. A failed download is the most common cause of "no audio generated". If incomplete, delete the folder and re-download manually from https://huggingface.co/jpgallegoar/F5-Spanish/tree/main into software directory/models/models--jpgallegoar--F5-Spanish.
2. Language code: you are using es-419 (Latin American Spanish). Try setting Target to plain Spanish (es) so the channel maps to the Spanish model without ambiguity, then re-test the Listen button.
3. Check the real error: open logs/YYYYMMDD.log in the software directory and look at the lines immediately before the DubbingSrtError — the actual exception (missing file, shape mismatch, CUDA error) will be there. If nothing useful appears, check whether _internal contains the f5/torch libraries.

If after a clean full-package install and a valid reference wav it still produces no audio, send the last ~30 lines of the log file from the logs/ folder so the underlying exception can be identified.
