No audio

[FMC-gclifford]

Hi All,

New user here (great application).

I see the audio bar jumping around but i'm not getting any volume on my clients. I've tried Chrome, Firefox and IE and none appear to have any audio.

I'm trying to just listen to Broadcast FM to get started as a test.

Am I missing something obvious?

Nothing obvious in the logs

Please provide the contents of the browser's console log (omitting any stack traces) so I can see what the client audio status is.

[FMC-gclifford]

interesting it seems to be working now - looks like it takes a few reloads of the website before it starts working?

[kpreid]

That's probably #125 then!

[FMC-gclifford]

I didn't see a definitive fix. is it still being worked on?

[kpreid]

It's not being actively worked on but I intend to fix it at some point. The fix will require new UI, a "play button" for the audio. (Which I think is a good idea anyway.)

You can use "site settings" to allow sound to auto-play by default on you shiny instance. Of course this will change the behaviour only on the system you are currently logged on. Click on the icon on the left of the URL on you browser. Select "site settings" -> "sound" and set "allow" reference:
