Just 18, installed pavucontrol and qas.
pavucontrol only says "connection failed: connection refused" when launched. Any idea what the workaround maybe?
yes, it is enabled through system control.
"connection failed: connection refused" ...... I have only seen this error when PulseAudio is not properly running.
I suggest the following to see if it would help .....
turn off PulseAudio in PCC - Hardware - Sound Configuration
reboot the PC immediately
then without doing anything else or launching any other app
use Synaptic to install (or reinstall) task-pulseaudio
When done, go to PCC - Hardware - Sound Configuration
and enable PulseAudio
On arriving at the Desktop this time, launch pavucontrol and see if the error still presents itself.
Hopefully that will sort things ..... please report back on the results.
