TTS with wyoming-piper creates mp3 files with multiple ID3 headers, which won't play back on some devices

[davidmonro]

The problem

I am trying to use tts.speak with the wyoming integration to produce output on an android tablet using the fullykioskbrowser app. This doesn't work; I can see from the web traffic that the tablet (repeatedly!) attempts to retrieve the resulting mp3 from the homeassistant server, but no sound results.

Using the google translate tts, does work (showing that the tablet can access and play cached TTS mp3 output just fine).

Directing the wyoming-piper tts output to a different media player (eg a chromecast) also works fine.

Analyzing the resulting mp3 file that is generated by the tts process, it has two ID3 headers stuck on the front.

If I copy this mp3 to the homeassistant local media folder and then play it on the tablet media player entity through the 'media' entry on the sidebar, it also fails to work (but does work if the target is a chromecast).

If I remove the first ID3 header from the mp3 file, I can play the resulting file through the media entry on the sidebar on the tablet.

I don't know if it is the tablet itself, or the media player entity exposed by fullykiosk, that is being picky. Either way, perhaps it would be best if the process didn't stick multiple ID3 headers on the file.

(Slightly confusingly one of the headers seems to indicate that the language should be been Spanish, given the es_ES string? I'm using the en_GB-alba-medium voice and everything is in English).
