Correct me if I am wrong, but if I get it correctly, you want to have a simultaneous output to your speakers in analog and usb hedphones in digital (or would it be a problem id the headphones were analog?). By default, you can only select one output device. The only way I know of to select multiple devices is:
-install pavucontrol and paprefs
- Code: Select all
sudo apt-get install pavucontrol && sudo apt-get install paprefs
-plug in your headphones
-run pavucontrol; under the "Configuration" tab select the profile of your speakers and headphones (translation: Izhod == Output, Vhod == Input)
-run paprefs; under the"" Simultaneous Output tab, check "Add virtual output device for simultaneous output on all local sound cards"
-now you just have to select the simultaneous output onder sound. Not sure how it's done in KDE. In Cinnamon, you just click the sound icon and select it or in the general sound preferences under the first tab first tab select it. You should be ready to go...
Oh, and if you anly want a specific application to use this setup, here's a great article on how to do so: http://matt.scharley.me/2012/03/29/puls ... vices.html
Hope this helps.
