like below fixes the issue Enumerate mutations and each mutation's addedNodes Enumerate node's child elements because mutations are coalesced during page loading using the superfast getElementsByTagName instead of the superslow querySelectorAll Don't use @grant none, which runs your userscript in the page context, unless you really need direct access to the page's JavaScript objects Use @run-at document-start to mute the audio during page loading

code :

// ==UserScript==
// @name     addicto
// @include  *
// @run-at   document-start
// ==/UserScript==

const sites = ['mako.co.il'];
if (sites.some(site => location.hostname.includes(site))) {
  new MutationObserver(mutations => {
    for (const m of mutations) {
      for (const node of m.addedNodes) {
        if (node.localName == 'audio') {
          audio.muted = true;
        } else if (node.children && node.children[0]) {
          for (const child of node.getElementsByTagName('audio')) {
            audio.muted = true;
          }
        }
      }
    }
  }).observe(document, {subtree: true, childList: true});

The sound muted after playing audio with Audio Queue on iOS for a while

hope this fix your issue The problem has been resolved.
The key point is, you can not let the audio queue buffer waits, you must keep feeding it, or it might be muted. If you don't have enough data, fill it with blank data.

code :

do 
{
    read_bytes_enabled = g_audio_playback_buf.GetReadByteLen();
    if (read_bytes_enabled >= kAudioQueueBufferLength)
{
    break;
}
    usleep(10*1000);
}
while (true);

read_bytes_enabled = g_audio_playback_buf.GetReadByteLen();
if (read_bytes_enabled < kAudioQueueBufferLength)
{
    memset(inBuffer->mAudioData, 0x00, kAudioQueueBufferLength);
}
else
{
    inBuffer->mAudioDataByteSize = kAudioQueueBufferLength;
}

How do I add some other audio to the muted section of an audio using ffmpeg?

By : user1087145

wish of those help The convenient way to do this is to trim the source and concat with the new audio.

code :

ffmpeg -i in.wav -i insert.wav -filter_complex "[0]atrim=0:94[pre];[0]atrim=124,asetpts=PTS-STARTPTS[post];[1]atrim=0:30[mid];[pre][mid][post]concat=n=3:v=0:a=1" out.wav

Audio tags in React app play wrong audio clips when list of audio clips is filtered

By : user3538059

With these it helps Currently your example application emits the following error: Warning: Each child in an array or iterator should have a unique "key" prop.. You would need to add a unique key to each item returned from Array.prototype.map(). This will help "React identify which items have changed, are added, or are removed" and in your situation ensure filtering can work effectively. In your case it looks like each URL is unique so perhaps that can be used as an effective key:

code :

  <div>
    <h1>Filter</h1>
    <input value={this.state.text} onChange={e => this.handleChange(e)} />
    <ol>
      {filteredList.map((item, index) => {
        return (
          <div key={item}>
            {item} -{" "}
            <audio controls preload="none">
              <source src={item} type="audio/mpeg" />
            </audio>
          </div>
        );
      })}
    </ol>
  </div>

Has IOS13 broken <audio> tags used as audio buffers connected to the audio context?

To fix this issue Unfortunately, AudioContext.createMediaElementSource has been broken since the release of iOS 13. The bug has been fixed: https://bugs.webkit.org/show_bug.cgi?id=203435. It's in Safari Technology Preview 99.
