error in play() with engine system: [Errno -9996] Invalid output device (no default output device)

[BookerShi]

from RealtimeTTS import TextToAudioStream, SystemEngine, AzureEngine, ElevenlabsEngine

engine = SystemEngine() # replace with your TTS engine

import ipdb;ipdb.set_trace()

stream = TextToAudioStream(engine) stream.feed("Hello world! How are you today?") print(f"type:{type(stream)}") print(f"stream:{stream}")

stream.play_async()

stream.play()

error in play() with engine system: [Errno -9996] Invalid output device (no default output device)

How can such problems be solved and what causes them

[BookerShi]

I checked my computer, and the sound card drivers are all intact

Sounds like a pyttsx3 can't detect your output device.

Pls run some basic example code like this to verify:

import pyttsx3 
engine = pyttsx3.init()
engine.say("hello")
engine.runAndWait()

I was unable to run this headless, I made some changes to fix the dependency issues in ubuntu 20.04, ubuntu22.04

I am having the same issue. After running the code suggested, I got this:

I am not good with linux, but maybe it might help if you try to install espeak, ffmpeg and libespeak1 as shown below:

sudo apt update && sudo apt install espeak ffmpeg libespeak1

@alibabadoufu Does this method resolve your problem?

[alibabadoufu]

No it doesn't. I guess because the server doesn't allow to connect with the sound card so it doesn't work for me.
