This means that the CODEC will no longer be held in reset (which presumably has a power benefit or something) even if jack detection isn't in use. What most devices do is have things like this be controlled via the bias level or other power management functions and then have jack detection hold the CODEC out of the lowest power states when it's active. --4ea6fdfknur5bqkt Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAll7PrwACgkQJNaLcl1U h9Bf2gf/c/0HewKx7J0GGIIyasdH7To5toi1CvxzHTez6akg53pFwCH9uEREYfM4 mPcN8xvT5auKVTS9JTciVw/axFZDr8HAjwsh/qz27VmV8pIOJBfO9UtJ+8vIycBU Ovw7voP3l3sxvGiTjKJa2NbXAaIoOaUW66uNdaEKTxAyLynSMmwzu4AKRN4b0GoE DC5/8rKbPgGTexdFGJmkKWx5WeNFvKF+fAhjlhifQsnOb/MPaDG36c0ee1VZ75yw +e+o/k52+nLUV6ht+LF3Tfk/LTw5ofPMQlyFbuN/FsjA9tAhYW95f7b6gLg12pwq 9PpNo7ySiVLA5ihqm67NVgLYDGPePw== =EdL0 -----END PGP SIGNATURE----- --4ea6fdfknur5bqkt--
