I'm using embedly's /oembed endpoint to get link previews for everything. However some links doesnt return already muted and plays a sound. I'm using angular and load the preview link like so

    <!-- Link Post Body With Embedded html -->
    <div [innerHTML]="sanitizedPreviewHtml" ></div>
    <!-- End Link Post Body  Embedded html -->

and I'm setting the "sanitizedPreviewHtml" like so,

      this.sanitizedPreviewHtml = this.sanitizer.bypassSecurityTrustHtml(this.topicSummary.previewHtml);
      this.previewHtml.nativeElement.muted = true;

But from time to time, the browser plays sound on my items. Even if I mute the gif, if I reload the page it sometimes (but not always) will play the sound again. this so far only happened on giphy links, such as this one

How can I make sure every preview like this I receive is muted?
