How does media controller API allow the media application to know there are
multi streaming playback devices ?
http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#multistream
via codec can reconfigure the independent headphone at runtime but some
codec require a reboot to select this multi steaming playback model
how does media controller api allow the application/pulseaudio server to
know whether surround5.1 and rear mic/line in for those 3 jacks motherboard
cannot be used at the same time ?
http://www.intel.com/support/motherboards/desktop/sb/cs-020642.htm#6ch
via codec using "smart51" switch and other codec use "channel mode" to
switch between 2 channels and 6 channels
5 jacks model may have "channel mode" to switch between 6 channels and 8
channels
some high-end notebook may switch from 2 channels to 8 channels when they
have four jacks (pink, blue , green and grey )
