Audio API daMediaElementAudioSource genera ceros debido a restricciones de acceso CORS porque estoy intentando reproducir una URL de SHOUTcast. No se que hacer; He probado todas las soluciones en internet pero nada funcionó. Cualquier ayuda será apreciada.

La URL funciona perfectamente con el elemento de audio, por lo que no se trata de la URL; Incluso he intentado algo comohttp://subdomain.domain.org:port/file.mp3. Y encontré en Internet personas que usan Icecast, que es.ogg tiene el mismo problema ¿Cómo arreglar esto?
