Ok, point taken. It's just not really a drop-in equivalent, given that
both the numid and the name string will change then.
I'll see when I'll find some time to do that. Your idea is to have a
"Master Playback Switch" for both the CPU and the Codec on each link, if
the driver implements either ->mute_stream or ->digital_mute, right? And
the control would default to "on"?
