What happen when the computer has no headphone jack ?
No mic jack and internal mic
Those thin mini itx motherboard use firmware to disable mixer and remove
all input pins
# Prevent the AA-loopback from being enabled which can pull in white noise
(ACI#380)
[hint]
mixer_nid = 0
Will the driver still power down the audio mixer and audio inputs ?
Seem driver still create capture device when there is no input pins
