[NOWEB] - Problems playing audio on Android even after implementing automatic MP3 conversion in the latest version

[williamsalathiel]

Describe the bug

I'm having trouble playing audio on Android. Even after implementing automatic MP3 conversion in the latest version, it won't play. I pass convert: true and it sends, but it won't play on Android.

It seems to me that the 'convert' implementation made for WEBJS was not applied in NOWEB

The iOS app and web work fine.

Version

Get the WAHA version by calling GET /api/sendVoice with convert: true

{
  "version": "2025.10.4",
  "engine": "NOWEB",
}

Any news? @devlikepro

[devlikepro]

checking, TY for the example 👍

[devlikepro]

Could you test in dev version?

• devlikeapro/waha-plus:dev — make sure to select the engine via the environment variable

• devlikeapro/waha-plus:dev-arm

Here's test we're using and also tested with the mp3 you sent - works with in all platforms.

  "file": {
    "mimetype": "audio/ogg; codecs=opus",
    "url": "https://github.com/devlikeapro/waha/raw/core/examples/voice.mp3"
  },
  "reply_to": null,
  "convert": true,
  "session": "default"
}

Please give a feedback after 🙏

I ran some tests following your example and it worked fine, but for some reason the base64 URLs aren't working.

@williamsalathiel could you share the example of base64 payload? Save it as some file.txt and attach here or share via gist - the full payload
