in patch_realtek.c
there is a snd_pci_quirk_vendor for all sony vaio to use
ALC269_FIXUP_SONY_VAIO
static const struct hda_fixup alc269_fixups[] = {
[ALC269_FIXUP_SONY_VAIO] = {
.type = HDA_FIXUP_PINCTLS,
.v.pins = (const struct hda_pintbl[]) {
{0x19, PIN_VREFGRD},
{}
}
},
SND_PCI_QUIRK(0x104d, 0x9073, "Sony VAIO",
ALC275_FIXUP_SONY_VAIO_GPIO2),
SND_PCI_QUIRK(0x104d, 0x907b, "Sony VAIO", ALC275_FIXUP_SONY_HWEQ),
SND_PCI_QUIRK(0x104d, 0x9084, "Sony VAIO", ALC275_FIXUP_SONY_HWEQ),
SND_PCI_QUIRK_VENDOR(0x104d, "Sony VAIO", ALC269_FIXUP_SONY_VAIO),
>> AFAIK the SONY has two microphones onboard.
do you mean the left and right channels are in inverted phase ?
if yes, try mute the right channel of Capture Switch
Simple mixer control 'Capture',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 127
Front Left: Capture 127 [100%] [30.00dB] [on]
Front Right: Capture 127 [100%] [30.00dB] [off]
usually the laptop use either pin sense of headphone jack or mic jack to detect
the headset instead of both
