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