No TTS voice response in Assist chat due to mTLS

[tomaciazek]

Home Assistant Android app version(s):
2025.11.4-full
Android version(s):
16
Device model(s):
Samsung Galaxy S22
Home Assistant version:
2025.12.4
Last working Home Assistant release (if known):
N/A
Description of problem, include YAML if issue is related to notifications:
When using mTLS authentication through Cloudflare, the Assist chat fails on playback of TTS recording provided by Piper. With mTLS protection policy disabled on Cloudflare, everything works fine. Surprisingly, when launching an audio debug stream, it works with mTLS enabled without issues too - I guess the debug mode is using different code / libraries for audio fetching / playback.

Did you try the new beta? Debug and release are sharing the same codebase it shouldn't have an impact. The only difference I can think of is that you didn't test the same version.

You can build the app in release mode like you did for debug and see if the issue is the same. Also I've migrated the player in Assist to ExoPlayer in this PR #6188 if you can try it to see if the same error occur.

launching an audio debug stream

I meant the option under Settings > Voice assistants > Debug > Run audio pipeline, not running a locally-built debug mode of the application 😅 . But I'll try your branch in a couple of days, when I have some time to set everything up - thanks for the suggestion!

Oh my bad I though you meant the debug companion app... In that case we cannot do anything on the app side debug and release are treated the same way.
