Title: Fix alternate audio track handling

There was an issue when default audio track from manifest was missing an url (ie: audio was contained inside ts). In this case audio tracks where not extracted from ts and we were ending with no audio.
Also DEFAULT attribute is optional and should be considered as NO when missing in alternate audio tracks
