ALSA: hda - Fix input source elements of secondary ADCs on Realtek
Since alc_auto_create_input_ctls() doesn't set the elements for the
secondary ADCs, "Input Source" elemtns for these also get empty, resulting
in buggy outputs of alsactl like:
control.14 {
comment.access 'read write'
comment.type ENUMERATED
comment.count 1
iface MIXER
name 'Input Source'
index 1
value 0
}
This patch fixes alc_mux_enum_*() (and others) to fall back to the
first entry if the secondary input mux is empty.
