So,

I go back and forth between many streaming sites, primarily using a PS3. Now, i have everything linked up for the best video and audio but verification is typically a pain given that all the streaming sites use different interfaces.

For example, Netflix will tell you if the audio track is stereo (2 chan) or 5.1. This can also be verified by my sound system which will tell me the source is coming through as 2/0/0, or 3/2/1, or 3/4/1 (for 7.1) .

However, I can connect my computer to the same sound system and tell my PC that the sound system is a 5.1 digital output. This means that anything I play on my computer, no matter the formatting of the source file, my sound system will always register 3/2/1 or 5.1 throughput. Thus, on the PC i have to check the AVI or MP4 to find out the source format sound channels to verify if it was originally encoded with 5.1 or stereo.

Additionally, in the Netflix application, I can use the "Display" button of the PS3 remote to get information about the title I am currently viewing, and it will say 240,288,480,720,1080 etc for video, as well as 2.0 or 5.1 for audio.
This being said, my soundsytem registers 3/4/1 for the sound output when using the CrunchyRoll application. Now I am pretty sure that NOTHING on CrunchyRoll, Netflix, or other format than a BluRay disc is actually coded for 7.1. This means it appears that the CrunchyRoll application simply outputs the same regardless of the source format.

I am wondering what methodologies, if any, there are to verify if a title is encoded with 5.1 and if so how to activate that audio format from the source? If a title is not encoded in 5.1 I would like it to stream through the PS3 as stereo (like Netflix does) so that I can utilize surround-decoding and other mixing features of my sound system for better sound.
When it only uses two channels of the 5.1, but transmits them as 5.1 I can't enable the surround mixing correctly.
(Personally, I'd like everything to be true 5.1 but wishes aren't horses, )

Thanks

If you actually want 5.1, you should buy the blu ray. Even when something is streamed and the audio is '5.1' it's a very compressed 5.1. So mixing stereo to output 5.1 would probably sound the same anyway, however if something is stereo, you should leave it at that, and not try mixing it as it won't be as accurate. Otherwise to actually answer your question, I don't know how you would find out what the audio properties on here are. They are all most likely stereo though which is completely fine.

Never get a sounds system whit less then 7.1 audio...

Anyhow, if the source file is recorded in one format then it doesn't really matter what audio system you've got since you can't change how something was recorded when it was recorded. Also, most Japanese dubbed anime is recorded in 2.0 channels whit localized releases having 5.1 and in some cases 6.1

Dubbed anime is an anathema. haven't even tried since Wicked City with it's bastardized ending due to Americanized dubbing.
That being said, i still get some 5.1 (albeit stream compressed) through other streaming services - hulu, amazon, netflix, etc. if crunchyroll is 2.0 only that is good to know.

btw - the sound mixing I'm talking about are like channel enhancers which don't alter the source distribution, but fill up the channel blends, so it comes through cleaner and clearer in my environment. no matter what the base encoding is, turning on the "surround decoder", always sounds better.

thanks,
