Hello,
I'm writing a UCM2 .conf file, depending on Device Tree options, some
kcontrols may or may not exist - how do I handle this in the BootSequence,
so alsactl does not error out if some controls don't exist?
I know there's a possible If condition to check if a control exists, but
how do I use that to conditionally append to the BootSequence?
Example (from ucm2/Intel/sof-hda-dsp/sof-hda-dsp.conf):
If.amute {
Condition {
Type ControlExists
Control "name='Auto-Mute Mode'"
}
True.BootSequence [
cset "name='Auto-Mute Mode' off"
]
}
The arrays are merged, thus any additional 'BootSequence []' will be handed as
extension.
