KDE - switching between speakers and headphones

Question

open source

Hello.
I have Arch, KDE I

have speakers connected to the analog jack on my mac and I have headphones (USB)
Sometimes you need to switch the sound for all programs from headphones to speakers and vice versa.

Is that possible? And will it work with flash?

Do you want PulseAudio? Then you can do whatever you want with pavucontrol.
And ... What does the poppy have to do with it? Do you have arch on a mac?
