7.1 Audio plays with channels missing

[mcrivera11]

I have 5.1 Surround .flac files that play very well on your extension, but when I load 7.1 (8-channels) .flac files the sound is not played correctly; for example a movie audio track, where the voices of the actors can't be heard.
Everything's ok when playing through Chrome's built-in player Ctrl+O, though.

Please fix this bug and make us appreciate your extension with even more power.
Many thanks.

**Of all videoplayer apps available for Chrome, this is the one that sounds better, very well equalized. Good job!

Hello! Thanks for bringing this up. Could you provide a sample video file? Something small preferably. On a side note, are you willing to give the latest version of the app a try? We have quite a few improvements that have been waiting to go out for quite some time now.

Here goes the sample:
sample7.1.zip
The voices can be heard when you give it a play on the Chrome local player or any other player like VLC. In this extension, no voices and only the background sound.

Sure, I'd love to test it! Send me instructions.

Hey, I found the issue. The app uses Web Audio API to provide volume amplification and audio delay capabilities. For some reason, 7.1 channel audio is mishandled by the API (drops 1 or more channels). I will continue looking into this. Any help from your end will be.....helpful. Is the channel drop happening for all 7.1 videos? About the beta testing; I will send you a zip in a while that you can add as an extension into your browser.

Yes, all videos with 8 audio channels play only 6.
I've found some literature that may be of good use to you:
HTML5_book.zip
Check out the Chapter 9, page 331.

**Oh, and I tested all videoplayer apps for Chrome as well and yours is the only one with this issue.
Still it's the one I like the most and I'll remain here.

I have attached a file with this comment. Download it. Extract it. Follow the steps listed here <https://developer.chrome.com/extensions/getstarted#unpacked> to load the folder as an app. It should now appear in your app menu. You can uninstall the older version to avoid confusion. This app contains a few improvements over the older version. Given your specific case, I have removed the app's ability to amplify volume beyond 100% and also the audio delay feature. This seems to have solved the missing channels issue, I will continue to look for the actual solution. In the meantime, any feedback from you on this version of the app will be very useful. Whenever you come across the app misbehaving, a screenshot of the developer's console (Ctrl+Shift+J) would be helpful for me to debug the issue. Thanks again for bringing up this issue! Improvements include: New screenshot shortcut (p). Partial FLV support. Some bug fixes. [app.zip](https://github.com/guancio/ChromeOsSubtitle/files/1306683/app.zip)

It worked! Brilliantly.
Everything's running just fine now, and it's not only it; The bass is very improved, giving the videos a punch of reality, yet not interfering with other higher frequencies.
I liked the new volume design, larger and easier to control.

After installing the app I just got one warning message:
"There were warnings when trying to install this extension:
'webview' is not allowed for specified extension ID."

But it didn't stop me from running it.

I really recommend you to keep this audio configuration for the final next release, it's pretty good.
While on it, I'm gonna keep this modification you've made for me and have loads of fun.

Thank you very much,
and have a good work.

I've tested every single Video Player, Multimedia Centres available for Windows and Linux, and this App wins the 1st place.
I use it on Vivaldi browser to playback even better. Give it a try and see if you like!
