+ * You can easily use this sample by adding below line on your DT file,
+ * and add new CONFIG to your .config.

+ *
+ *	CONFIG_SND_AUDIO_GRAPH_CARD2
+ *	CONFIG_SND_AUDIO_GRAPH_CARD2_CUSTOM_SAMPLE
+ *	CONFIG_SND_TEST_COMPONENT
+ *
+ *
+ * You can indicate more detail each device behavior as debug if you modify
+ * "compatible" on each test-component. see below
+ *

+ *
+ * Below sample doesn't use "format" property,
