Indeed, Thanks for pointing this out.
I have question regarding this DAPM control.
Here, I put the control in DAPM so it can help with the pop noise
reduction, but I think it would be nice if the user could force the
mute if he wants to.

Would it be OK to add a user control and some logic so the output is
enabled only if DAPM and the user agree it should ?
