Dify version

1.5.1

Plugin version

0.0.8

Cloud or Self Hosted

Cloud

Steps to reproduce

  1. Connect to Minimax
  2. Set a random TTS model as default system model
  3. Try on a workflow with TTS enabled

✔️ Error log

No error thrown, the audio is simply not played, I have checked the network tab and found that no tts_messsage vent was streaming back to the client, only see tts_message_end event
This problem does not happen on tts models from OpenAI according to my own test
Seem Minimax plugin needs some update

I can't reproduce this on cloud.dify.ai
can you try the Audio tool and use the minimax TTS model?

Thanks for your quick response
Let me explain again to you my situation: I need to have the auto-play feature in the Chatflow, not using external tool
Please watch this video for better understanding the problem: https://drive.google.com/file/d/1G5EDIeudJfI_3yZ4LeiRONZEKwt2ys67/view?usp=sharing

Here is what I did while recording:

  1. trigger the chatflow with a greeting message, wait for AI to response
  2. open the network TAB from browser console to debug the API streaming response and found that there is no 'tts_message' event sent back - the one that triggers audio play
  3. I tried to trigger the TTS manually by clicking the 'audio' icon but still no audio
  4. I switched to OpenAI model and it worked normally

I watched your video and found that when you clicked the play button then got an empty response

but when I use the same model of minimax in the same platform, I can get the response:

I think there might be an issue with your Minimax account. Using the audio tool could help determine whether this account problem.

thank you, seem there is something wrong with the account, the balance still has 90$ remaining but when I test the TTS API, it responses with insufficient_balance. So weird
