Describe the bug

Audio can only be played once. On subsequent attempts to play the audio file, nothing happens — no playback starts and no errors are shown.

Code sample

Code

import flet as ft
import flet_audio_recorder as ftar
import flet_audio as fta

def main(page: ft.Page):
    page.horizontal_alignment = ft.CrossAxisAlignment.CENTER
    page.appbar = ft.AppBar(title=ft.Text("Audio Recorder"), center_title=True)

    path = "test-audio-file.wav"

    def handle_start_recording(e):
        print(f"StartRecording: {path}")
        audio_rec.start_recording(path)

    def handle_stop_recording(e):
        output_path = audio_rec.stop_recording()
        print(f"StopRecording: {output_path}")
        if page.web and output_path is not None:
            page.launch_url(output_path)
        page.update()

    def handle_state_change(e):
        print(f"State Changed: {e.data}")

    audio_rec = ftar.AudioRecorder(
        on_state_changed=handle_state_change,
    )

    audio_play = fta.Audio("non-existent", autoplay=False, volume=6)
    page.overlay.append(audio_play)

    def handle_start_play(e):
        audio_play.src = path
        page.add(ft.Text(f"play audio file: {audio_play.src}"))
        audio_play.update()
        audio_play.play()

    print(f"audio recorder: {audio_rec}")
    page.overlay.append(audio_rec)
    page.update()

    page.add(
        ft.ElevatedButton("Start Audio Recorder", on_click=handle_start_recording),
        ft.ElevatedButton("Stop Audio Recorder", on_click=handle_stop_recording),
        ft.ElevatedButton("Play", on_click=handle_start_play),
    )


ft.app(main)

To reproduce

Run the app using flet run --android.

Scan the QR code on the Android device.

Start recording with AudioRecorder.

Stop the recording to save the audio file.

Play the recorded file using Audio.

Try to play the same audio file again.

Playback does not start, no errors in logs.

Expected behavior

It should be possible to play the same audio file multiple times without issues.
