例子：
設置節點0x19參數為SET_PIN_WIDGET_CONTROL，值為0x24
$ hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x24
nid = 0x19, verb = 0x707, param = 0x24
command 0x01970724 --> result = 0x00000000
也可以寫成：
$ hda-verb 0x19 0x707 0x24
nid = 0x19, verb = 0x707, param = 0x24
command 0x01970724 --> result = 0x00000000
CodecCommander經常使用的命令：
$ hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x25
$ hda-verb 0x21 SET_UNSOLICITED_ENABLE 0x83
備注：
字符串不區分大小寫
此外，它不一定是完整的字符串，但只能是唯一的
例如par和PARAMETER的參數是相同的
set_a就足以代替SET_AMP_GAIN_MUTE
