Hi everyone, I've been fighting with getting the Audio component to play sounds through a web browser for a few weeks now and am at a bit of an impasse. I have it setup to correspond to an alarm tag that when true will flip the playback value to true, and play the file until the alarm is no longer true.
I can get the sound to play when in the Ignition Designer without issue, however every time I try to get it to play in a browser window, nothing! I have verified the playback is set to true, volume of the element is at 100, and that computer speakers are on, but nothing still! Any suggestions or advice would be greatly appreciated!
This may be a permissions issue in your browser, you normally need to allow sound effects to play before the browser will let you.
Can maybe try with different browsers and check the browser settings
Have you tried looking in the web browsers console for any errors as well?
It seems to be working on Chrome now which is a starting point! Oddly in Edge (which runs on Chromium) still no dice, despite trusting the site and allowing everything, however there was no explicit Sound allowance field for it.
What's more is the Raspi I'm trying to run this on via Chromium browser is also unable to playback the sound! Maybe Chromium just hates ignition! 
I'll try to get a copy of Chrome on it and report back!
Or maybe the sound file uses a patent-encumbered codec? Chrome has DRM and licenses to use such, Chromium does not.

I have been trying to use .wav files, I'm unaware if they are a patented codec, but I can always give some other formats a whirl if that is the issue
