Can someone help to look into this issue? This is a serious problem.
Same problem here on FF 50.1.0 + Flash 24r0!
Prior to the recent update, Flash 11 for Linux didn't support the audio notifications at all. After the update to Flash 24, it appears that Flash now sends audio notifications to Firefox, but doesn't mute when we ask it to. This is almost certainly an Adobe issue and I've raised it with our partner engineers.

I've opened an enhancement request for this. The bug is FLASH-4187266
After further investigation, we've observed a difference in behavior with Firefox on Linux vs other platforms. Here's the analysis from our engineer: To control mute/unmute, Firefox passes "NPNVmuteAudioBool" to plugin via "NPP_SetValue", this works well on Windows, but on Linux, flash player never receives "NPNVmuteAudioBool" from "NPP_SetValue", so I think this is a bug of Firefox Linux.

Jeromie, here's what I've found: it appears that when Firefox calls NP_GetEntryPointsFunc on Linux, Flash fills in the NPPluginFuncs structure but setvalue (NPP_SetValue) remains null: http://searchfox.org/mozilla-central/rev/e95e4ed8b5229a29dacc32c0b90968df5e7a6ff3/dom/plugins/base/npfunctions.h#117 So you are not receiving any NPP_SetValue functions from the browser (on Linux), which probably breaks all of the following features: * private browsing notifications * audio muting * CSS zoom notifications I think it's likely that you've coded a NPP_SetValue but just haven't included it in the glue code that sets up the initial structure.
Great, thanks for the insight. I've kicked this bug back with your input.
Today I got the update for flashplugin. Muting on Antergos is now working. 13:12:18 ~$ pacman -Qs flashplugin local/flashplugin 22.214.171.124-1 Adobe Flash Player
We believe that this was fixed (on Linux) in the most recent Flash release. Please reopen if you're still seeing this with Flash 126.96.36.199 or later.
