Audacity "Device Toolbar" problems

I want to record what is coming from the PC speakers with the Linux version of Audacity, but the Device Toolbar doesn't fully appear. Here's a screenshot of the toolbar:

The same settings can be made in Edit > Preferences > Devices, so you don’t really need this toolbar. It’s also possible that selecting them in that dialog may make them appear on the toolbar as well? - I don’t know.

Ok, thank you for that. I also have another problem. I can’t open Audacity; it says that another copy is already running, but it isn’t.

Open a terminal and enter

Code:
killall audacity

If it then opens, my guess would be that it was not correctly shut down by you. I do not have audacity installed, I cannot verify this.

killall audacity didn’t do anything.

Hi,

open system monitor and see if you can find audacity there then end process!:
