62 * In windows it seems to be required for all controls to have a volume switch
63 * In alsa that's optional
65 * I assume for playback controls, that there is always a playback volume switch available
68 * For capture controls, it is needed that there is a capture switch and a volume switch,
69 * It doesn't matter whether it is a playback volume switch or a capture volume switch.
70 * The code will first try to get/adjust capture volume, if that fails it tries playback volume
71 * It is not pretty, but under my 3 test cards it seems that there is no other choice:
72 * Most capture controls don't have a capture volume setting
74 * MUX means that only capture source can be exclusively selected,
75 * MIXER means that multiple sources can be selected simultaneously.
