Requires MODIFY_AUDIO_SETTINGS and RECORD_AUDIO. No audio device will be available for recording

Open Source Development Extension Development

I'm trying to develop an extension that uses a WebView with a page that accesses the microphone.

I've tried setting the permissions for this in my Java code

@UsesPermissions(permissionNames = "android.permission.INTERNET, " +
    "android.permission.WRITE_EXTERNAL_STORAGE, android.permission.READ_EXTERNAL_STORAGE, " +
    "android.permission.RECORD_AUDIO, android.permission.MODIFY_AUDIO_SETTINGS, android.webkit.resource.AUDIO_CAPTURE")

I added WebSettings

webViewSettings.setJavaScriptEnabled(true);
webViewSettings.setMediaPlaybackRequiresUserGesture(false);

And I've tried granting the requests I see come in:

webView.setWebChromeClient(new WebChromeClient() {
    @Override
    public void onPermissionRequest(final PermissionRequest request) {
        activity.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                request.grant(request.getResources());
            }
        });
    }
});

(I do see that get called with a request for android.webkit.resource.AUDIO_CAPTURE)

But I'm still hitting permissions errors. When the javascript running in my WebView tries to access the microphone, I get permission denied errors, and I see this in my adb log:

cr_media: Requires MODIFY_AUDIO_SETTINGS and RECORD_AUDIO. No audio device will be available for recording

Can anyone help me work out what I've missed, please?
