Hi all,  
I installed thinlinc on Ubuntu 22.04 both on a desktop version and on a server version with the mate environment and I can’t get the sound redirection to work properly.  
I can hear desktop notifications, but Firefox and Chromium don’t make any sound. I tried restarting pulse audio to no avail. Also I had a look at Firefox details and it’s showing it’s using the dummy audio driver.  
These two installs were clean, purposely built to test thinlinc on Proxmox 7.3.  
I would appreciate any help.  
FYI - I had to run host +SI:localuser:`id -un to get Firefox to be able to connect to the window server.  
Thank you

I did another test now with a fresh Ubuntu Desktop 20.04 VM on the same VM host and audio works fine, so it seems there is an incompatibility between thinlinc 4.14.0 and Ubuntu 22.04 pulseaudio.

Thank you

I tried Pop OS, which is based on Ubuntu Desktop 22.02 and it seems to work better than Ubuntu. Sound works, and Firefox starts out of the box without having to use `host +SI:...`

Cheers

In case anyone else stumbles across this issue, the cause of the problem is that Firefox (and other apps) is installed as a Snap by default on Ubuntu 22.04.

Snap applications are limited in many ways, and one consequence is that sound won’t work when connecting remotely.

Here’s a page describing how to install a regular DEB version of Firefox on Ubuntu:

> **[How to Install Firefox as a .Deb on Ubuntu 22.04 (Not a Snap) - OMG! Ubuntu](https://www.omgubuntu.co.uk/2022/04/how-to-install-firefox-deb-apt-ubuntu-22-04)**
>
> A short guide on how to install Firefox from a PPA on Ubuntu 22.04 and remove the Firefox Snap. Doing this gets you a faster Firefox that can do more OOTB.

With the real version of Firefox, sound works just fine in ThinLinc on Ubuntu 22.04.
