Good finding!

Probably what solved your audio problems is reinstalling pulse audio.

at-spi2-core adds some functionality for screen readers. It is nice if the dbus warning dissapears. I will check and add it to the instructions

.
The only thing thats left now is to sort out why the mic has no audio input . When i key up and talk its just a dead carrier . some times i get audio and most of the time nothing .
I have used two usb sound cards and two mics and it still the same .
Some times when i hit PTT it keys up then cuts out after 1 sec .

Is there anything im missing here ?

I can hear everything just fine but i have had bother with mic input from the start .

This is the two sound cards i use .

Make sure the usb card is connected before you start the application. If you start it from a console you will see some information about what audio input and output interfaces are being selected by default. One missing and important feature is being able to select the audio devices.

Ok audio out works as it should and i am getting sound in with the mic .

The only thing is that i hit PTT my call sign will come up on the brandmister network for 1 sec then cut off and other times it will not show up at all on the network .

Is there a fire wall or someing blocking my audio going up on the network ? At the min i cant make QSO .

What am i missing here ?

There is a "talk out time" at the DMRStation.ini file. Default value is 180. What abt yours?
