Pulseaudio "Access Denied" on Fedora 25 with Awesome WM as desktop environment

From reading the forum it looks like the problem is fixed now (by adding 'x11') ?

It is true that the original issue I faced was when the app didn't include the 'x11' plug.

Without x11, the application worked fine on Fedora with Gnome Shell but didn't work with Awesome WM.

I have not tried the snap on Fedora *with* Awesome VM *after* adding 'x11'.

Hi, Tizonia is still experiencing AppArmor denials in Window Managers like Awesome WM and Cinnamon.

See https://github.com/tizonia/tizonia-openmax-il/issues/588

The Snap of Tizonia works perfectly fine in Gnome 3 or Unity.

This kind of looks like the user in question tried to run a program as
root and rather than use the standard permissions to perform a task,
needed to use root's capabilities to perform the task.

Can you provide some instructions on how exactly to reproduce this issue?
(Probably it would be best to do this in a new bug report, a two year old
bug report may not be the best place to put it.)

Thanks

Seth, thanks for your reply.

Indeed the user in https://github.com/tizonia/tizonia-openmax-il/issues/588 was running the program as root, so maybe that wasn't a good example.

But still the problem stated in this launchpad bug report is valid at least in my personal case.

I use Awesome Window Manager in all my systems and the snap of Tizonia has never worked there. But it works without fault with the default WMs (Unity and Gnome 3).

So to reproduce this issue, just get any recent version of Ubuntu, and install Awesome WM

$ sudo apt install awesome

Then install thhe snap of Tizonia and try to play something from YouTube. E.g.:

$ tizonia --youtube-audio-mix-search "AC/DC thunderstruck"

You will get this:
