I think this is to allow users to switch off sound for all channels but
it seems silly to have 4 controls doing the same thing.
We now have two options:
- one control to switch off sound for all channels
- one controll per DAC

What do you mean by "users should be switch controls" ?
Should we use SND_SOC_DAPM_SWITCH instead of SND_SOC_DAPM_MUX?

We are still learing the inner details of ASoC.
Thank you for your help.
