50 List of the connections between audio
51 components; each entry is a pair of strings, the first being the
52 connection's sink, the second being the connection's source;
53 valid names for sources and sinks are the WM8994's pins (as
54 documented in its binding), and the jacks on the board -
55 For samsung,aries-wm8994: HP, SPK, RCV, LINE, Main Mic, Headset Mic,
56 or FM In
57 For samsung,fascinate4g-wm8994: HP, SPK, RCV, LINE, Main Mic,
58 or HeadsetMic
59 Deprecated, use audio-routing.
