1447 | AC97 Quirk Option | ||
1448 | ================= | ||
1449 | |||
1450 | The ac97_quirk option is used to enable/override the workaround for | ||
1451 | specific devices on drivers for on-board AC'97 controllers like | ||
1452 | snd-intel8x0. Some hardware have swapped output pins between Master | ||
1453 | and Headphone, or Surround (thanks to confusion of AC'97 | ||
1454 | specifications from version to version :-) | ||
1455 | |||
1456 | The driver provides the auto-detection of known problematic devices, | ||
1457 | but some might be unknown or wrongly detected. In such a case, pass | ||
1458 | the proper value with this option. | ||
1459 | |||
1460 | The following strings are accepted: | ||
1461 | - default Don't override the default setting | ||
1462 | - disable Disable the quirk | ||
1463 | - hp_only Bind Master and Headphone controls as a single control | ||
1464 | - swap_hp Swap headphone and master controls | ||
1465 | - swap_surround Swap master and surround controls | ||
1466 | - ad_sharing For AD1985, turn on OMS bit and use headphone | ||
1467 | - alc_jack For ALC65x, turn on the jack sense mode | ||
1468 | - inv_eapd Inverted EAPD implementation | ||
1469 | - mute_led Bind EAPD bit for turning on/off mute LED | ||
1470 | |||
1471 | For backward compatibility, the corresponding integer value -1, 0, | ||
1472 | ... are accepted, too. | ||
1473 | |||
1474 | For example, if "Master" volume control has no effect on your device | ||
1475 | but only "Headphone" does, pass ac97_quirk=hp_only module option. | ||
