I recently purchased the roccat kulo headset which comes with a nice USB soundcard, completely functional under linux :). Howsoever I now struggle to easily siwtch between my laptops integrated soundcard, connected to my stereo and my headset connected by the roccat soundcard. Running aplay -l retureturns the following:

**** List of PLAYBACK Hardware Devices ****  
card 0: PCH [HDA Intel PCH], device 0: CONEXANT Analog [CONEXANT Analog]  
  Subdevices: 1/1  
  Subdevice #0: subdevice #0  
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]  
  Subdevices: 1/1  
  Subdevice #0: subdevice #0  
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]  
  Subdevices: 1/1  
  Subdevice #0: subdevice #0  
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]  
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Kulo [ROCCAT Kulo], device 0: USB Audio [USB Audio]
  Subdevices: 1/1  
  Subdevice #0: subdevice #0  

I know I could provide a .asoundrc howsoever I'd prefer a more straight forward way to switch the output device globally.

If pulseaudio is an option, pavucontrol provides a gui to select the output of each stream, and you can do the same using the command line with pactl. This question explains how. – Vincent Nivoliers Nov 12 '12 at 16:49
What do you mean with "globally"? For already running applications? For all users? – CL. Nov 12 '12 at 17:03
"globally" should be for already running applications – Momo Nov 12 '12 at 20:19

asoundconf-gtk, included in the AUR package asoundconf, is a GUI that lets you select the default sound card.

It can be installed via yaourt with:

yaourt asoundconf

@HalosGhost I just tried it, and it installed it. I had to choose it from a search-like prompt, is that what you mean? – RyanTM Oct 20 '14 at 14:52
Then yaourt's behavior is even less predictable than when I last used it. My -1 for yaourt will stay. – HalosGhost Oct 20 '14 at 14:54
