control.34 { iface CARD name 'Line Jack' value false comment { access
read type BOOLEAN count 1 } } control.35 { iface CARD name 'Line Out
Front Jack' value false comment { access read type BOOLEAN count 1 } }
control.36 { iface CARD name 'Line Out Surround Jack' value false
comment { access read type BOOLEAN count 1 } } control.37 { iface CARD
name 'Line Out CLFE Jack' value false comment { access read type BOOLEAN
count 1 } } control.38 { iface CARD name 'Front Headphone Jack' value
