Cordova audio element not working with Blob on iOS

[jdnichollsc]

Hello Ionic Team,

I'm trying to play a blob audio and it's not working from iOS, but it's working as expected from Android.

Code:

• component logic:

  // audioBlob is a Blob recorded using Cordova File and Media Plugins
  const src = createObjectURL(audioBlob);
  this.audioUrl = this.sanitizer.bypassSecurityTrustResourceUrl(src);

• component render:

  <audio #audio [src]="audioUrl"></audio>

Error:

Any help is really appreciated! <3

Ok, It's working using source html elements inside audio elements :)
