Sonilo returned no audio data

Error message

Sonilo returned no audio data

What it means

Raised when the stream ended cleanly (a complete event was received) but zero audio bytes were accumulated. The protocol was honored yet the provider delivered a finished, empty result. It is separated from error 93 to distinguish a truncated stream from a legitimate-but-empty generation, typically a server-side failure that still emits complete.

Solutions

Retry the task once; an empty-but-complete result is frequently a transient provider fault.
Check account credits and usage on the Sonilo dashboard for evidence the generation ever ran.
Try a different source video or prompt to rule out content-triggered silent rejection.
If reproducible, report to Sonilo support: complete with zero audio_chunk events violates their own protocol.

Defensive patterns

Strategy: retry

Try / catch

try:
    audio = request_bgm(video, out, prompt)
except SoniloError as exc:
    if "returned no audio data" in str(exc):
        # complete-but-empty is usually a silent provider failure: retry once
        retry_once()
    raise

Prevention

Treat complete-with-zero-audio as a provider health signal; count occurrences and alert past a threshold.
Never promote the empty temp file to the output path; the library already prevents this, keep callers from bypassing it.

When it happens

Trigger: The provider emits a complete event immediately (or after only title or meta events) because generation failed silently, the video was rejected after upload, or credits were exhausted without an error event; a server bug produces a zero-length result.

Common situations: Provider incidents where failures bypass the error channel; unsupported video content accepted at upload then skipped server-side; quota exhausted mid-request with a graceful-complete bug.
