Hello to all of you .

I am running Ubuntu 20.04.5 LTS with the Gnome Desktop environment on an older HP Compaq-Pro-4300 64-bit.

I am one of the very few people on the globe that have encountered and embraced the game Linux Air Combat,
the first Combat Flight Simulator for Linux, where you can (dog-)fight and fly with WWII planes .

see https://askmisterwizard.com/2019/Lin...xAirCombat.htm

The voice communication between players is handled by Mumble, and there I have a big problem with :

After configuring Mumble to work with input and output both set to 'JACK' all Pulseaudio output stops .
So I changed the input and output to 'Pulseaudio', which worked for the Linux Air Combat game BUT :

Now my volume handle on the top right does NOT have any effect anymore on all sound output !

Can anyone explain how that is possible ?

Thanks in advance to read and post your thoughts on this .

Your volume appears to be turning up the microphone to me.

Anyhow, with pulse I reach for pavucontrol & the configuration tab. Sometimes it's trying to use stupid devices, and you can set levels too. You don't need the mixer - just the setup tool.

Thanks @business_kid for your reply .

Sorry that I didn't saw it more early .

You are right that there are other solutions to set that volume,
but I would like to know how to set it right again !

So this thread is not closed yet !

PLEASE read this thread fully !

Thanks in advance,

yours truly,
