audio: primary desc check for sonification_respectful

Ringtone will be played on combo device and touch tone is routed to
headset which results in device switch during ringtone playback. As
a result, audio glitches are audible.
If sonfication_respectful strategy is used by primary desc, we will
treat all non music streams with the same stragey which will avoid
device switch.
