Audio codec support and surround sound

One of the supported audio codecs is ac3 which is 5.1 audio capable. It can be used in conjunction with mp4 and hls streams.

Thanks for the reply. So HLS can use ac3 in both 5.1 and stereo? I was under the impression only aac was supported via HLS. And aac is not supported for 5.1?

firmware v3.0 only will support the HLS CODEC tag for ac3.

Great, good to know.

And aac, is 5.1 pass through over HLS supported for that also or just ac3?

It's not support AC3 - 5.1 Extrac to Wave file, I'm looking for Software with Extract AC3-5.1 Channel and AC3-Stereo but AC3 Decoder 1.2.6 support only AC3-Stereo by low quality.

The box does ac3 pass-thru only.

Sorry to drag up an old thread, but can anyone confirm whether the released version of 3.0 supports ac3 in HLS? I can get it working on my Roku2 unit, but HLS streams with ac3 don't work at all on my Roku1 (HD-XR) unit running the latest 3.0 firmware. Just want to know if I should stop try and just put a version check in place.

Bumpity bump bump.

Any further info if firmware v3.0 definitively supports ac3 in HLS?

Have you run your tests under firmware 3.1? Some of us are beginning to speculate that the unsuccessful attempt to support AC3 in HLS in 3.x firmware may be the reason why HLS is not working properly.

Certainly as noted here

the failures of HLS in the beta are pretty much replicated in the released 3.0 firmware that broke my usage and others. 3.1 has some similar failures with HLS, but the audio problems are more notable. This post describes one of the audio problems some are seeing in more detail

No I have not tested ac3 in 3.1 yet. And HLS works fine in 3.x for my usage as long as I use aac stereo audio.

A) Not to sound harsh, but that link is to a locked thread. I'd prefer not to dig up locked threads.
B) At least one of the links (to the plex forums) in that post is dealing with the Roku2 and the 4.x firmware. The bug there had to do with nested m3u8 files and IIRC it was resolved in one of the R2 updates. In short, it has nothing to do with 3.x and the issue I'm asking about here.
C) the other 2 links deal with symptoms that are nothing like the symptoms I experience with ac3 audio.

Those symptoms are nothing like I see with ac3 in HLS. When I try and play an ac3 HLS stream on 3.0, the roku displays the loading screen and nothing else. No video nor audio is ever played. The same HLS stream with aac audio plays with no issues on 3.x. As far as I can tell, the issues being described have not occurred for any other Plex users on 3.x either.

I followed your thread in the other forum and I'm sorry you are having issues, but I think it is separate from this particular issue/question.
