Description Anish Bhatt 2009-07-08 13:19:52 UTC 
Version:            (using KDE 4.2.4)
Compiler:          gcc 4.4 
OS:                Linux
Installed from:    Unlisted Binary Package

I use a pair of external USB speakers which show up as a seperate sound card.My media keys(mute/vol +-) are set to control the master channel on my comp soundcard. These are set as global shortcuts. The speakers also have media keys on them,

When I connect the external speakers, phonon correctly switches to the soundcard in the external speaker. However, the media keys are still controlling the onboard soundcard channels. THe media keys on the speakers return the same key codes as the regular media keys, rendering them useless to control the external speakers. The media keys are now controlling the onboard soundcard, while the soundcard in use is the one shown by the speakers.

There should be a way to switch key profiles such that the global shortcuts are remapped to the currently selected soundcard, rather than having to switch manually everytime. Possibly, preference levels for key profiles similar to how soundcards currently have precedence in kde.

If I am not completely mistaken the global shortcuts are handled by KMix, so essentially KMix needs to do some switching. As a matter of fact I suppose this should be working flawlessly with PulseAudio and KMix already.
