HLS streams with ac3 audio not working on chromecast

Question

Chromecast doesn't stream videos which have ac3 audio. only streams that have the aac codec are working. is there a way to achieve ac3 audio stream support on chromecast while using hls? The sample HLS streams tested

1. AC3 https://s3-ap-southeast-1.amazonaws.com/ht-brightcove/Dar_20/AC3/playlist.m3u8
2. AAC https://s3-ap-southeast-1.amazonaws.com/ht-brightcove/Dar_20/5AAC/playlist.m3u8

Answer 1

No. Chromecast can not decode ac3. https://developers.google.com/cast/docs/media
