if hardware cannot distinguish headset and headphone
does this mean that the function if the Jack is determined by capture
source ?
internal Mic = headphone
headset Mic = headset
headphone Mic = mic
control.10 {
iface MIXER
name 'Capture Source'
value 'Internal Mic'
comment {
access 'read write'
type ENUMERATED
count 1
item.0 'Headphone Mic'
item.1 'Headset Mic'
item.2 'Internal Mic'
}
}
if you only use headset and want automic when you plugged in
you need to giveup the support of Mic jack and headphone by a new hint which
change the logic
