The alsasink currently relies and a list of prefered caps for how it handles 
surround sound. After a discussion with Wim and also some emails to ALSA devel 
it needs to be changed to do the following:

a) Instead of prefered caps it should use the virtual alsa devices. So by
default alsasink should just use the stereo device so that downmixing to stereo
is always happening.

b) The applications should be able to choose a different device through an
element attribute like the 'surround51' device for 51 surround. Applications
should not use this device though for mono/stereo streams, but instead use the
default stereo output device.
