- * and three stereo sources (Playback 1-2, Playback 3-4, Playback 5-6).
- * Each channel should be mapped just once to one source.
- * If mapped multiple times, only one source will play on given channel

+ * devices have different configurations, there seems to be canonical values
+ * for specific capture/playback types:  See the definitions of these below.
  *
- * For recording, duplicate mapping is OK. We will get the same signal multiple times.
- *
- * Channels 7-8 are in both directions fixed to FX SEND / FX RETURN.
- *
- * See also notes in the quirks-table.h file.
+ * The wValue is masked with the stereo channel number. e.g. Setting Ch2 to
