Piper TTS fails on long messages

[joshuazd]

Describe the issue you are experiencing

When trying to using Piper to generate a long tts message (on Sonos speakers, in my case), the audio never plays on the speaker. This seems to happen at around 35 seconds, for me. Anything shorter than that works fine.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Home Assistant Operating System

Which add-on are you reporting an issue with?

Piper

What is the version of the add-on?

1.4.0

Steps to reproduce the issue

1. Run a media_player.play_media service call with a long piper tts message, e.g.

service: media_player.play_media
target:
  entity_id: media_player.soundbar
data:
  media_content_type: music
  media_content_id: >-
    media-source:https://tts/tts.piper?message="This is a short message. This is a
    slightly longer message that takes longer to say. This is an even longer
    message where I'm going to keep talking for awhile so the length of the
    audio will increase. This is a 4th message to increase the length of the
    audio and I will keep talking and talking to make this longer. Lorem ipsum
    dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
    incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis
    nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
    consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse
    cillum dolore eu fugiat nulla pariatur."
  announce: false

2. The message fails to play on the speaker.
   The same thing happens if I send announce: true, but with it set to false, I can see a message in the Sonos app that says "Unable to play '' - the connection to was lost"
   Shorter messages, which is pretty much anything under 35 seconds, always works, and anything longer seems to always fail.
   I have tried restarting various things (Home Assistant, the addon, etc.), clearing the TTS cache, and none of that has worked.
