Audio streaming is not working properly

[snarb]

Describe the bug

I am having the same goal as i #3299 to make stream audio works. This could be from remote server or from several local wav files (when first is processed second is generated).

I have checked this solution: yield-ing the output audio file to an Audio output component. it is not working properly,

def transcribe(audio)
    flist = ['33056526426.wav', '65074181139.wav']
    for i in range(2):
        if i > 0:
            time.sleep(2)
         yield flist[i]

Not working and hangs UI thread during sleep. With single file works properly.

Example from this one #1775 is also looks like not working properly gradio/demo/stream_audio/run.py. or doesn't looks like supports real time playback, it is not clear how to stream audio when microphone is not triggering add_to_stream, and how to trigger output audio stream update from some background thread that is making processing. It would be so nice to have some working example .

Reproduction

def transcribe(audio)
flist = ['33056526426.wav', '65074181139.wav']
for i in range(2):
if i > 0:
time.sleep(2)
yield flist[i]

2)```
import gradio as gr
import numpy as np
import time

def add_to_stream(audio, instream):
    time.sleep(1)
    if audio is None:
        return gr.update(), instream
    if instream is None:
        ret = audio
    else:
        ret = (audio[0], np.concatenate((instream[1], audio[1])))
    return ret, ret


with gr.Blocks() as demo:
    inp = gr.Audio(source="microphone")
    out = gr.Audio()
    stream = gr.State()
    clear = gr.Button("Clear")

    inp.stream(add_to_stream, [inp, stream], [out, stream])
    clear.click(lambda: [None, None, None], None, [inp, out, stream])


if __name__ == "__main__":
    demo.launch()
