Why isn't just_audio Flutter Android simulator playing any audio from a streaming service?

Question

The following code (snippet from the final app) works fine in iOS, and I don't get any errors when running it on Android Pixel 2 Simulator API 33.

import 'package:just_audio/just_audio.dart';
...
...
class _MyHomePageState extends State<MyHomePage> {
  late final WebViewController controller;

  final AudioPlayer player = AudioPlayer();

 @override
  void initState() {
    super.initState();

    controller = WebViewController()
      ..loadRequest(
        Uri.parse('https://renewfm.org/wp-content/themes/radiostation/showPlaying.php?device=web'),
      );

    //WidgetsBinding.instance.addPostFrameCallback( (_) async {
    //    await player.setUrl('https://renewfm.org/renewfm-stream.php');
    //    await player.play();
    //  }
    //);
    player.setUrl('https://renewfm.org/renewfm-stream.php');
    player.play();
  }
...

iOS starts playing it fine, with or without the WidgetsBinding.instance.addPostFrameCallback code. The Debug output for Android seems to indicate it is trying to play:

D/BufferPoolAccessor2.0(19617): bufferpool2 0x77d419df0818 : 5(40960 size) total buffers - 1(8192 size) used buffers - 213/218 (recycle/alloc) - 5/432 (fetch/transfer)
D/BufferPoolAccessor2.0(19617): bufferpool2 0x77d419df0818 : 5(40960 size) total buffers - 1(8192 size) used buffers - 417/422 (recycle/alloc) - 5/840 (fetch/transfer)
...

But there's no volume. I have the simulator volume control up.

Here's my Manifest:

    <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

    <application
        android:label="renewfm"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"

            <meta-data

            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

Thanks for the help!

Tried it with a different emulator and it worked. Retried it with the API 33 and it worked. Go figure.
